These plants are widely consumed by Chadian population, but few research studies have focused on their nutritional and health benefits. The aim is to stimulate research, investment, and in-depth studies on these plants to encourage their use and transformation in Chad. Abelmoschus esculentus, Hibiscus sabdariffa, and Corchorus olitorius L. are Malvaceae species with medicinal properties and traditional use in Chad. They contain essential amino acids and have antinociceptive, anxiolytic, anti-inflammatory, and anxiolytic activities. Their extract has hypoglycemic potential as a preventative or adjunct therapy for pre-diabetes or diabetes. Hibiscus sabdariffa is rich in essential vitamins, including vitamin A, which is beneficial for eyes, anti-aging, and sight. Its vitamin C helps fight free radicals and ensures good resistance to infections. Corchorus olitorius L. has a nutritional composition ranging from 1.2 to 34.4 mg/100 g and is known for its mucilaginous seeds, young tops and leaves, and silky hair. These plants have potential medicinal applications in antidiabetic, anti-gastritis, and prebiotic fields, and play a significant role in neural development and health. Promoting their use in Chad requires conservation programs, public policies, and local population planting. Future research should focus on their nutritional and medicinal properties, targeting underutilized species to address micronutrient deficiencies. Enhancing bioconservative properties and communication of these plants’ virtues are crucial for their optimal availability and protection.展开更多

Juss called Muraї in Arabic and the seeds of Trigonella foenum-graecum called Helbé in Arabic in order to treat the most frequently cited diseases such as malaria, the common cold, mother and newborn care, and typhoid. Ethnobotanical surveys were conducted from September to December 2022, in three markets in the city of N’Djamena, based on individual interviews using a semi-structured questionnaire, with 30 herbalists and traditional practitioners. Phytochemical screening analyses of the organs of four plants were carried out in the chemistry and biology laboratory of the Faculty of Exact and Applied Sciences (FSEA) following a standard protocol established by [1] and slightly modified by [2] [3]. The results of the surveys identified 68 species divided into fifty-five (55) genera and twenty-seven (27) families, the most represented of which were Caesalpiniaceae (10 species), Mimosaceae (5 species) and Combretaceae (4 species). The leaves were the most commonly used parts (43%), with decoction (70%) the most frequently used method of preparation. The oral route was the most popular with 73% of recipes. The phytochemical study revealed a wealth of secondary metabolites such as Trapezoidal Sterols, Alkaloids, Tannins, Flavonoids, Free Quinones, Anthocyane, Anthraquinones, Saponosides and Heterosides. These results can be considered as a source of information for scientific research in the field of phytochemistry and pharmacology.展开更多

Despite the increasing acceptance of medicinal plant use in combination with conventional antituberculosis drugs in treatment of tuberculosis (TB) in Uganda, there is paucity of knowledge on their combination effect. Aim: This research aimed to determine combination activity of standard antituberculosis drugs with extracts of Zanthoxylum leprieurii Guill. & Perr. and Rubia cordifolia L., the two common antituberculosis medicinal plants in Uganda, against pansensitive (H37Rv) and multi-drug resistant (MDR) Mycobacterium tuberculosis strains. Materials and Methods: Two reference MTB strains (H37Rv and MDR strain) were inoculated on Middlebrook 7H11 medium containing a combination of standard antituberculosis drugs and methanol extracts of Z. leprieurii and R. cordifolia at varying concentrations. The number of colonies on the plates was observed and counted weekly for up to 8 weeks. In vitro combination activity was determined using proportion method. Mean percentage inhibition was calculated for the reduction of number of colonies on drug-extract combination medium in relation to drug-extract-free control medium. Results: Drug-extract combinations showed good combination activity against Mycobacterium tuberculosis strains when compared with individual standard anti-TB drugs. This was more exhibited against MDR strain. There was however a reduction in percentage inhibition when extracts were combined with ethambutol and streptomycin against H37Rv strain. Conclusions: Zanthoxylum leprieurii and Rubia cordifolia in combination with standard anti-TB drugs exhibited increased in vitro activity against Mycobacterium tuberculosis, especially MDR-TB strain. This justifies the local use of these plants in traditional treatment of tuberculosis especially in resistant cases in Uganda.展开更多

Medicinal plants, renowned for their therapeutic properties, host endophytic bacteria that produce bioactive compounds. Understanding antibiotic resistance dynamics in these bacteria is vital for human health and antibiotic efficacy preservation. In this study, we investigated antibiotic resistance profiles in endophytic bacteria from five medicinal plants: Thankuni, Neem, Aparajita, Joba, and Snake plant. We isolated and characterized 113 endophytic bacteria, with varying resistance patterns observed against multiple antibiotics. Notably, 53 strains were multidrug-resistant (MDR), with 14 exhibiting extensive drug resistance (XDR). Thankuni-associated bacteria displayed 44% MDR and 11% XDR, while Neem-associated bacteria showed higher resistance (60% MDR, 13% XDR). Aparajita-associated bacteria had lower resistance (22% MDR, 6% XDR), whereas Joba-associated bacteria exhibited substantial resistance (54% MDR, 14% XDR). Snake plant-associated bacteria showed 7% MDR and 4% XDR. Genus-specific distribution revealed Bacillus (47%), Staphylococcus (21%), and Klebsiella (11%) as major contributors to MDR. Our findings highlight diverse drug resistance patterns among plant-associated bacteria and underscore the complexity of antibiotic resistance dynamics in diverse plant environments. Identification of XDR strains emphasizes the severity of the antibiotic resistance problem, warranting further investigation into contributing factors.展开更多

The rise of resistance for modern antibiotic in infections treatment imposed us order alternatives. The study objective was to contribute in the knowledge of medicinal plants uses in urinary infections treatment in N’Djamena (Chad) in view for amelioration the traditional medicine in future. Methodology: The study was conducted in the city of N’Djamena in the Republic of Chad that interviewed 60 traditherapists on using 11 plants for urinary tract infections treatment. The methodology of this study consisted of the knowledge of medicinal plants that used by traditherapists, and the plants identification was done in the laboratory of IRED at Farcha. Results: A total of 60 traditherapists was interrogated on the plants used in the treatment of urinary tract infections among the population of N’Djamena. The majority of traditherapists interrogated in this study were male with the rate of 61.67% against female with the rate of 38.33%. The age range of traditherapists was between 20 to 80 years, 25 (41.67%) from the age range between 30 - 50 years and 35 (58.33%) in age range from 50 to 70 years. For the origin of their knowledge, the study showed that 72% of traditherapists inherited the knowledge from their family, while 15% inherited from the family and from training. The ethnic groups of the traditherapists were Sara (16%), Maraba (12%) and Massa (11%). According to the results, 18.33% were illiterates, 49% attended primary school and 33.34% the secondary school. Our study found that 11 species of plants belonging to 11 families were used in the treatment of urinary tract infection and the Ziziphus spina-christi was the most represented. According to traditherapists the Ziziphus spina-christi, Cassia obovata and Euphorbia hirta were the most frequent plants used in the urinary tract infections treatment. The parts of plants used in the treatment were leaves and bark, grained leaves and entire plants with the proportion of 50%, 16.67 and 15% respectively. Conclusion: This study revealed that the medicinal plants are variously used in the treatment of infection urinary tract in the city of N’Djamena.展开更多

文摘Chinese wingnut(Pterocarya stenoptera)is a medicinally and economically important tree species within the family Juglandaceae.However,the lack of high-quality reference genome has hindered its in-depth research.In this study,we successfully assembled its chromosome-level genome and performed multiomics analyses to address its evolutionary history and synthesis of medicinal components.A thorough examination of genomes has uncovered a significant expansion in the Lateral Organ Boundaries Domain gene family among the winged group in Juglandaceae.This notable increase may be attributed to their frequent exposure to flood-prone environments.After further differentiation between Chinese wingnut and Cyclocarya paliurus,significant positive selection occurred on the genes of NADH dehydrogenase related to mitochondrial aerobic respiration in Chinese wingnut,enhancing its ability to cope with waterlogging stress.Comparative genomic analysis revealed Chinese wingnut evolved more unique genes related to arginine synthesis,potentially endowing it with a higher capacity to purify nutrient-rich water bodies.Expansion of terpene synthase families enables the production of increased quantities of terpenoid volatiles,potentially serving as an evolved defense mechanism against herbivorous insects.Through combined transcriptomic and metabolomic analysis,we identified the candidate genes involved in the synthesis of terpenoid volatiles.Our study offers essential genetic resources for Chinese wingnut,unveiling its evolutionary history and identifying key genes linked to the production of terpenoid volatiles.
文摘Medicinal plants have long been used to treat various diseases in both indigenous and non-indigenous populations of Mindanao,Philippines.Here,we extracted data from ethnobotanical studies to compile a comprehensive list of these medicinal plants and identify how and for what purpose they are most commonly used.We identified 530 verified medicinal plant species across 372 genera in 118 families.The two most frequently cited species were Euphorbia hirta and Psidium guajava.The most represented family was Fabaceae and the most represented genus was Ficus.A total of 28 medicinal plant species are designated as threatened at the national or global level;of these,11 are endemic to the Philippines.Medicinal plant preparations most commonly use leaves for oral administration to treat various diseases such as digestive issues,including diarrhea.This study underscores the need for further ethnobotanical investigations,particularly in areas lacking records.It also emphasizes the need for conservation of threatened and endemic medicinal plants to ensure sustainable utilization of this valuable resource.
文摘Drought poses a significant challenge,restricting the productivity of medicinal and aromatic plants.The strain induced by drought can impede vital processes like respiration and photosynthesis,affecting various aspects of plants’growth and metabolism.In response to this adversity,medicinal plants employ mechanisms such as morphological and structural adjustments,modulation of drought-resistant genes,and augmented synthesis of secondary metabolites and osmotic regulatory substances to alleviate the stress.Extreme water scarcity can lead to leaf wilting and may ultimately result in plant death.The cultivation and management of medicinal plants under stress conditions often differ from those of other crops.This is because the main goal with medicinal plants is not only to increase the yield of the above-ground parts but also to enhance the production of active ingredients such as essential oils.To elucidate these mechanisms of drought resistance in medicinal and aromatic plants,the current review provides a summary of recent literature encompassing studies on the morphology,physiology,and biochemistry of medicinal and aromatic plants under drought conditions.
文摘Endothelial function plays a pivotal role in cardiovascular health,and dysfunction in this context diminishes vasorelaxation concomitant with endothelial activity.The nitric oxide-cyclic guanosine monophosphate pathway,prostacyclin-cyclic adenosine monophosphate pathway,inhibition of phosphodiesterase,and the opening of potassium channels,coupled with the reduction of calcium levels in the cell,constitute critical mechanisms governing vasorelaxation.Cardiovascular disease stands as a significant contributor to morbidity and mortality among individuals with diabetes,with adults afflicted by diabetes exhibiting a heightened cardiovascular risk compared to their non-diabetic counterparts.A plethora of medicinal plants,characterized by potent pharmacological effects and minimal side effects,holds promise in addressing these concerns.In this review,we delineate various medicinal plants and their respective biochemical constituents,showcasing concurrent vasorelaxant and anti-diabetic activities.

文摘The burgeoning field of bioengineering has witnessed significant strides due to the advent of stem cell models,particularly in their application in advanced therapy medicinal products(ATMPs).In this review,we examine the multifaceted impact of these developments,emphasizing the potential of stem cell models to enhance the sophistication of ATMPs and to offer alternatives to animal testing.Stem cell-derived tissues are particularly promising because they can reshape the preclinical landscape by providing more physiologically relevant and ethically sound platforms for drug screening and disease modelling.We also discuss the critical challenges of reproducibility and accuracy in measurements to ensure the integrity and utility of stem cell models in research and application.Moreover,this review highlights the imperative of stem cell models to align with regulatory standards,ensuring using stem cells in ATMPs translates into safe and effective clinical therapies.With regulatory approval serving as a gateway to clinical adoption,the collaborative efforts between scientists and regulators are vital for the progression of stem cell applications from bench to bedside.We advocate for a balanced approach that nurtures innovation within the framework of rigorous validation and regulatory compliance,ensuring that stem cell-base solutions are maximized to promote public trust and patient health in ATMPs.
文摘Vascular calcification is a crucial risk factor that affects the incidence and mortality of cardiovascular disease in chronic kidney disease patients.Modern medicine relies on calcium-phosphorus binding agents,calcium mimetics,active vitamin D,and hemodialysis to prevent and treat vascular calcification,however,their efficacy is unsatisfactory and adverse reactions often occur.Medical plant therapy can act as an integrative regulator in patients with chronic kidney disease-associated vascular calcification,which can significantly improve patients’symptoms,but its specific mechanism has not been fully elucidated yet.In this paper,we reviewed the domestic and international theoretical studies on the pathogenesis mechanism of chronic kidney disease-associated vascular calcification in recent years,summarized eight active ingredients of medicinal plants as well as four compound formulas for improving chronic kidney disease-associated vascular calcification,and explored the mechanism of action of herbal medicine,which will provide a new strategy for promoting the prevention and treatment of vascular calcification.

文摘This review explores the nutritional and health benefits of three vegetable plants in Chad: Abelmoschus esculentus, Hibiscus sabdariffa, and Corchorus olitorius L. These plants are widely consumed by Chadian population, but few research studies have focused on their nutritional and health benefits. The aim is to stimulate research, investment, and in-depth studies on these plants to encourage their use and transformation in Chad. Abelmoschus esculentus, Hibiscus sabdariffa, and Corchorus olitorius L. are Malvaceae species with medicinal properties and traditional use in Chad. They contain essential amino acids and have antinociceptive, anxiolytic, anti-inflammatory, and anxiolytic activities. Their extract has hypoglycemic potential as a preventative or adjunct therapy for pre-diabetes or diabetes. Hibiscus sabdariffa is rich in essential vitamins, including vitamin A, which is beneficial for eyes, anti-aging, and sight. Its vitamin C helps fight free radicals and ensures good resistance to infections. Corchorus olitorius L. has a nutritional composition ranging from 1.2 to 34.4 mg/100 g and is known for its mucilaginous seeds, young tops and leaves, and silky hair. These plants have potential medicinal applications in antidiabetic, anti-gastritis, and prebiotic fields, and play a significant role in neural development and health. Promoting their use in Chad requires conservation programs, public policies, and local population planting. Future research should focus on their nutritional and medicinal properties, targeting underutilized species to address micronutrient deficiencies. Enhancing bioconservative properties and communication of these plants’ virtues are crucial for their optimal availability and protection.

The leaves were the most commonly used parts (43%), with decoction (70%) the most frequently used method of preparation. The oral route was the most popular with 73% of recipes. The phytochemical study revealed a wealth of secondary metabolites such as Trapezoidal Sterols, Alkaloids, Tannins, Flavonoids, Free Quinones, Anthocyane, Anthraquinones, Saponosides and Heterosides. These results can be considered as a source of information for scientific research in the field of phytochemistry and pharmacology.
文摘BACKGROUND Colonization with Helicobacter pylori(H.pylori)has a strong correlation with gastric cancer,and the virulence factor CagA is implicated in carcinogenesis.Studies have been conducted using medicinal plants with the aim of eliminating the pathogen;however,the possibility of blocking H.pylori-induced cell differentiation to prevent the onset and/or progression of tumors has not been addressed.This type of study is expensive and time-consuming,requiring in vitro and/or in vivo tests,which can be solved using bioinformatics.Therefore,prospective computational analyses were conducted to assess the feasibility of interaction between phenolic compounds from medicinal plants and the CagA oncoprotein.AIM To perform a computational prospecting of the interactions between phenolic compounds from medicinal plants and the CagA oncoprotein of H.pylori.METHODS In this in silico study,the structures of the phenolic compounds(ligands)kaempferol,myricetin,quercetin,ponciretin(flavonoids),and chlorogenic acid(phenolic acid)were selected from the PubChem database.These phenolic compounds were chosen based on previous studies that suggested medicinal plants as non-drug treatments to eliminate H.pylori infection.The three-dimensional structure model of the CagA oncoprotein of H.pylori(receptor)was obtained through molecular modeling using computational tools from the I-Tasser platform,employing the threading methodology.The primary sequence of CagA was sourced from GenBank(BAK52797.1).A screening was conducted to identify binding sites in the structure of the CagA oncoprotein that could potentially interact with the ligands,utilizing the GRaSP online platform.Both the ligands and receptor were prepared for molecular docking using AutoDock Tools 4(ADT)software,and the simulations were carried out using a combination of ADT and AutoDock Vina v.1.2.0 software.Two sets of simulations were performed:One involving the central region of CagA with phenolic compounds,and another involving the carboxy-terminus region of CagA with phenolic compounds.The receptor-ligand complexes were then analyzed using PyMol and BIOVIA Discovery Studio software.RESULTS The structure model obtained for the CagA oncoprotein exhibited high quality(C-score=0.09)and was validated using parameters from the MolProbity platform.The GRaSP online platform identified 24 residues(phenylalanine and leucine)as potential binding sites on the CagA oncoprotein.Molecular docking simulations were conducted with the three-dimensional model of the CagA oncoprotein.No complexes were observed in the simulations between the carboxy-terminus region of CagA and the phenolic compounds;however,all phenolic compounds interacted with the central region of the oncoprotein.Phenolic compounds and CagA exhibited significant affinity energy(-7.9 to-9.1 kcal/mol):CagA/kaempferol formed 28 chemical bonds,CagA/myricetin formed 18 chemical bonds,CagA/quercetin formed 16 chemical bonds,CagA/ponciretin formed 13 chemical bonds,and CagA/chlorogenic acid formed 17 chemical bonds.Although none of the phenolic compounds directly bound to the amino acid residues of the K-Xn-R-X-R membrane binding motif,all of them bound to residues,mostly positively or negatively charged,located near this region.CONCLUSION In silico,the tested phenolic compounds formed stable complexes with CagA.Therefore,they could be tested in vitro and/or in vivo to validate the findings,and to assess interference in CagA/cellular target interactions and in the oncogenic differentiation of gastric cells.
文摘Introduction: Resistance to antituberculosis drugs and adverse drug reactions remain the leading causes of tuberculosis therapeutic failure globally. Despite the increasing acceptance of medicinal plant use in combination with conventional antituberculosis drugs in treatment of tuberculosis (TB) in Uganda, there is paucity of knowledge on their combination effect. Aim: This research aimed to determine combination activity of standard antituberculosis drugs with extracts of Zanthoxylum leprieurii Guill. & Perr. and Rubia cordifolia L., the two common antituberculosis medicinal plants in Uganda, against pansensitive (H37Rv) and multi-drug resistant (MDR) Mycobacterium tuberculosis strains. Materials and Methods: Two reference MTB strains (H37Rv and MDR strain) were inoculated on Middlebrook 7H11 medium containing a combination of standard antituberculosis drugs and methanol extracts of Z. leprieurii and R. cordifolia at varying concentrations. The number of colonies on the plates was observed and counted weekly for up to 8 weeks. In vitro combination activity was determined using proportion method. Mean percentage inhibition was calculated for the reduction of number of colonies on drug-extract combination medium in relation to drug-extract-free control medium. Results: Drug-extract combinations showed good combination activity against Mycobacterium tuberculosis strains when compared with individual standard anti-TB drugs. This was more exhibited against MDR strain. There was however a reduction in percentage inhibition when extracts were combined with ethambutol and streptomycin against H37Rv strain. Conclusions: Zanthoxylum leprieurii and Rubia cordifolia in combination with standard anti-TB drugs exhibited increased in vitro activity against Mycobacterium tuberculosis, especially MDR-TB strain. This justifies the local use of these plants in traditional treatment of tuberculosis especially in resistant cases in Uganda.

文摘Antibiotic resistance poses a significant global health threat, necessitating a thorough understanding of its prevalence in various ecological contexts. Medicinal plants, renowned for their therapeutic properties, host endophytic bacteria that produce bioactive compounds. Understanding antibiotic resistance dynamics in these bacteria is vital for human health and antibiotic efficacy preservation. In this study, we investigated antibiotic resistance profiles in endophytic bacteria from five medicinal plants: Thankuni, Neem, Aparajita, Joba, and Snake plant. We isolated and characterized 113 endophytic bacteria, with varying resistance patterns observed against multiple antibiotics. Notably, 53 strains were multidrug-resistant (MDR), with 14 exhibiting extensive drug resistance (XDR). Thankuni-associated bacteria displayed 44% MDR and 11% XDR, while Neem-associated bacteria showed higher resistance (60% MDR, 13% XDR). Aparajita-associated bacteria had lower resistance (22% MDR, 6% XDR), whereas Joba-associated bacteria exhibited substantial resistance (54% MDR, 14% XDR). Snake plant-associated bacteria showed 7% MDR and 4% XDR. Genus-specific distribution revealed Bacillus (47%), Staphylococcus (21%), and Klebsiella (11%) as major contributors to MDR. Our findings highlight diverse drug resistance patterns among plant-associated bacteria and underscore the complexity of antibiotic resistance dynamics in diverse plant environments. Identification of XDR strains emphasizes the severity of the antibiotic resistance problem, warranting further investigation into contributing factors.
