Bearing this in mind, our research was designed to compare the efficacy of three concentrations of dried SS(at 0.2%, 0.3%, and 0.6%) against tocobiol(a synthetic antioxidant) as a positive control(at 0.3% concentration). This comparison was conducted under three distinct storage conditions namely accelerated ageing(60 ℃), exposure to light at ambient temperature, and darkness, to evaluate their impact on preventing severe oxidation and extending oil shelf-life. Oxidation state evolution was evaluated through peroxide value(PV), free fatty acid(FFA), anisidine value(p-AV), K_(270)value(conjugated trienes), total oxidation index(TOTOX), iodine value(IV), and fatty acid composition(FA). Our results revealed notable differences in stability tracking parameters. Specifically, these parameters were higher in samples stored under accelerated conditions, followed by the samples stored in ambient light, while those stored in darkness showed the highest stability among the three storage conditions. Supplementation of sunflower oil with SS and tocobiol significantly enhanced its oxidation stability. Notably, SS exhibited exceptional effectiveness in stabilizing sunflower oil regardless of SS dose, with the highest efficacy observed at 0.6%. This was evidenced by the slower rate of oxidation parameters under various storage conditions, highlighting a superior antioxidant activity compared to both the non-enriched oil and tocobiol-enriched oil. Furthermore, saffron stigmas, used as a natural supplement,contributed to the preservation of polyunsaturated fatty acids, indicating its potential as a robust source of natural antioxidants in sunflower oil. These attributes position SS as a promising alternative to synthetic antioxidants, offering opportunities to enhance the nutritional quality and extend edible oil shelf-life.展开更多

Of these, accumulating trials reveal positive effects of the spice saffron （Crocus sativus L.） for the treatment of depression. A comprehensive and statistical review of the clinical trials examining the effects of saffron for treatment of MDD is warranted. OBJECTIVE： The purpose of this study was to conduct a meta-analysis of published randomized controlled trials examining the effects of saffron supplementation on symptoms of depression among participants with MDD. SEARCH STRATEGY： We conducted electronic and non-electronic searches to identify all relevant randomized, double-blind controlled trials. Reference lists of all retrieved articles were searched for relevant studies. INCLUSION CRITERIA： The criteria for study selection included the following： （1） adults （aged 18 and older） with symptoms of depression, （2） randomized controlled trial, （3） effects of saffron supplementation on depressive symptoms examined, and （4） study had either a placebo control or antidepressant comparison group. DATA EXTRACTION AND ANALYSIS： Using random effects modeling procedures, we calculated weighted mean effect sizes separately for the saffron supplementation vs placebo control groups, and for the saffron supplementation vs antidepressant groups. The methodological quality of all studies was assessed using the Jadad score. The computer software Comprehensive Meta- analysis 2 was used to analyze the data. RESULTS： Based on our pre-specified criteria, five randomized controlled trials （n = 2 placebo controlled trials, n = 3 antidepressant controlled trials） were included in our review. A large effect size was found for saffron supplementation vs placebo control in treating depressive symptoms （M ES = 1.62, P 〈 0.001）, revealing that saffron supplementation significantly reduced depression symptoms compared to the placebo control. A null effect size was evidenced between saffron supplementation and the antidepressant groups （M ES = -0.15） indicating that both treatments were similarly effective in reducing depression symptoms. The mean Jadad score was 5 indicating high quality of trials. CONCLUSION： Findings from clinical trials conducted to date indicate that saffron supplementation can improve symptoms of depression in adults with MDD. Larger clinical trials, conducted by research teams outside of Iran, with long-term follow-ups are needed before firm conclusions can be made regarding saffron＇s efficacy and safety for treating depressive symptoms.展开更多

The production of this substance has attracted human interest, since ancient cultures, for its medicinal and culinary properties. Because of saffron high economic value, sometimes, since Middle Ages, it is adulterated with other vegetal materials, dyes or synthetic molecules. Object of this work was the study of one of the best world saffron: Civitaretenga (AQ, Central Italy) C. sativus. Taste, color and aroma of Civitaretenga spice were determined, according to international standards (ISO/Technical Specification 3632), to define its high quality. A biochemical approach was then applied to obtain a secondary metabolite profile of this product. So, crocins, total phenolic content, flavonoids and phenolic acids were detected by HPLC-DAD and spectrophotometric analysis. Moreover, in vitro antioxidant properties and in vivo antineoplastic effects, on highly metastatic murine B16-F10 melanoma cell line, were successfully revealed in Civitaretenga C. sativus extract. All these data confirmed the elevated quality of Civitaretenga saffron and its highly reducing and chemopreventive activity.展开更多

Crocus specialized metabolites, crocins, are biosynthesized in distant species, Gardenia (eudicot) and Crocus (monocot), and the evolution of crocin biosynthesis remains poorly understood. With the chromosome-level Crocus genome assembly, we revealed that two rounds of lineage-specific whole genome triplication occurred, contributing important roles in the production of carotenoids and apocarotenoids. According to the kingdom-wide identification, phylogenetic analysis, and functional assays of carotenoid cleavage dioxygenases (CCDs), we deduced that the duplication, site positive selection, and neofunctionalization of Crocus-specific CCD2 from CCD1 members are responsible for the crocin biosynthesis. In addition, site mutation of CsCCD2 revealed the key amino acids, including I143, L146, R161, E181, T259, and S292 related to the catalytic activity of zeaxanthin cleavage. Our study provides important insights into the origin and evolution of plant specialized metabolites, which are derived by duplication events of biosynthetic genes.展开更多

INCLUSION CRITERIA： The criteria for study selection included the following： （1） adults （aged 18 and older） with symptoms of depression, （2） randomized controlled trial, （3） effects of saffron supplementation on depressive symptoms examined, and （4） study had either a placebo control or antidepressant comparison group. DATA EXTRACTION AND ANALYSIS： Using random effects modeling procedures, we calculated weighted mean effect sizes separately for the saffron supplementation vs placebo control groups, and for the saffron supplementation vs antidepressant groups. The methodological quality of all studies was assessed using the Jadad score. The computer software Comprehensive Meta- analysis 2 was used to analyze the data. RESULTS： Based on our pre-specified criteria, five randomized controlled trials （n = 2 placebo controlled trials, n = 3 antidepressant controlled trials） were included in our review. A large effect size was found for saffron supplementation vs placebo control in treating depressive symptoms （M ES = 1.62, P 〈 0.001）, revealing that saffron supplementation significantly reduced depression symptoms compared to the placebo control. A null effect size was evidenced between saffron supplementation and the antidepressant groups （M ES = -0.15） indicating that both treatments were similarly effective in reducing depression symptoms. The mean Jadad score was 5 indicating high quality of trials. CONCLUSION： Findings from clinical trials conducted to date indicate that saffron supplementation can improve symptoms of depression in adults with MDD. Larger clinical trials, conducted by research teams outside of Iran, with long-term follow-ups are needed before firm conclusions can be made regarding saffron＇s efficacy and safety for treating depressive symptoms.
文摘The numerous studies indicate leaves of plants are a rich source of bioactive compounds that can be a valuable source of compounds used in the pharmaceutical and cosmetic industries.Aim of this study was to investigate the chemical composition and the antioxidant property of Crocus speciosus leaves.Primary phytochemical screening of C.speciosus leaves revealed the presence of some following compound categories such as phenolic compounds,aminoacids,saponins,proteins,tannins,triterpenoids,glycosides,polysaccharides.The total flavonoids and phenolic compounds content were determined spectrophotometrically and by HPLC-DAD and HPLC-MS.Antiradical activity was determined by ABTS radical-cation scavenging method,spectrophotometrically.The total amount of flavonoids in C.speciosus leaves was 1.07±0.02 mg RE/g(p<0.05),the total amount of phenolic compounds was 0.41±0.01 mg GAE/g(p<0.05).By HPLC-DAD-MS analysis the presence of the mangiferin,chlorogenic acid,isoorientin,kaempferol,hyperoside,and isoquercitin was established for the first time in Crocus leaves.The antiradical activity of C.speciosus leaves extracts was 150.08±4.5μmol/g(p<0.05)and its was mainly attributed to phenolic compounds content.The high amounts of flavonoids and antiradical activity in C.speciosus leaves suggests promising phytochemical and pharmacological study of this Crocus species.
文摘Saffron, the most expensive spice in the world, is got by Crocus sativus L. stigmas. The production of this substance has attracted human interest, since ancient cultures, for its medicinal and culinary properties. Because of saffron high economic value, sometimes, since Middle Ages, it is adulterated with other vegetal materials, dyes or synthetic molecules. Object of this work was the study of one of the best world saffron: Civitaretenga (AQ, Central Italy) C. sativus. Taste, color and aroma of Civitaretenga spice were determined, according to international standards (ISO/Technical Specification 3632), to define its high quality. A biochemical approach was then applied to obtain a secondary metabolite profile of this product. So, crocins, total phenolic content, flavonoids and phenolic acids were detected by HPLC-DAD and spectrophotometric analysis. Moreover, in vitro antioxidant properties and in vivo antineoplastic effects, on highly metastatic murine B16-F10 melanoma cell line, were successfully revealed in Civitaretenga C. sativus extract. All these data confirmed the elevated quality of Civitaretenga saffron and its highly reducing and chemopreventive activity.
文摘ITS(Internal Transcription Spacer of nuclear ribosomal DNA)regions method was applied to identify and study the phylogenetic relationships existing between 41 individuals of Crocus,including 8 species collected in Iran(4 crop and 8 wild individuals)and 16 species(2 crop and 27 wild individuals)already registered in GenBank(NCBI).PCR amplifications were performed using the primer designed on the nucleotide sequence of nuclear region(ITS).A total of 12 sequences were obtained and registered in NCBI database.In particular,4 of these sequences were not already present in the scientific library.Nucleotide polymorphic sites were counted for ITS(N=97).The results showed that,the Cytosine base is the most abundant nucleotide.Relatively high conservation was observed in the ITS regions of the populations(0.761).Each sample could be distinguished from the others in the phylogenic trees developed based on the data obtained by ITS barcode genes.In general,ITS sequence indicating high resolution at the species level is very suitable for phylogenetic studies in the Crocus family.Phylogenetic analysis demonstrated the genetic relationship between crop saffron and wild Crocus species.According to the results of this study,the wild species of C.cartwrightianus and C.oreocreticus were considered as the closest relatives of the saffron.The results of the study also indicated that,the different ecotypes of C.sativus may have evolved through independent events probably due to the geographic and environmental pressures.

文摘Crocus sativus (saffron) is a globally autumn-flowering plant, and its stigmas are the most expensive spice and valuable herb medicine. Crocus specialized metabolites, crocins, are biosynthesized in distant species, Gardenia (eudicot) and Crocus (monocot), and the evolution of crocin biosynthesis remains poorly understood. With the chromosome-level Crocus genome assembly, we revealed that two rounds of lineage-specific whole genome triplication occurred, contributing important roles in the production of carotenoids and apocarotenoids. According to the kingdom-wide identification, phylogenetic analysis, and functional assays of carotenoid cleavage dioxygenases (CCDs), we deduced that the duplication, site positive selection, and neofunctionalization of Crocus-specific CCD2 from CCD1 members are responsible for the crocin biosynthesis. In addition, site mutation of CsCCD2 revealed the key amino acids, including I143, L146, R161, E181, T259, and S292 related to the catalytic activity of zeaxanthin cleavage. Our study provides important insights into the origin and evolution of plant specialized metabolites, which are derived by duplication events of biosynthetic genes.
文摘Objective:The aim of this study is to investigate the phytochemical and the long-term anti-neuropathic potentials of Crocus sativus cultivated in the University botanical garden,and explore its most bioactive compounds and their underlying mechanisms of action.Methods:Phytochemical analysis and bio-guided isolation-procedures including RP-HPLC and1 H and13 C NMR utilizing biological models of diabetes,inflammation,and diabetic-neuropathy were used.Cultivated saffron(S-RCED)and Spanish-saffron stigma(S-SP)alone or in combination with Camellia sinus(CS)were investigated.Results:The RP-HPLC analyses showed the presence of picrocrocin,crocin I,crocin II,crocin I’,crocin II’,and safranal(SAF)in both S-SP and S-RCED extracts with higher-concentrations.It had been shown that SAF was the most bioactive-compound in Crocus sativus.Both S-SP and S-RCED possessed significant(P<0.05)anti-diabetic activities in acute(6 h),subchronic(8 d)and chronic(8 weeks)models.S-RCED had been proven with more hypoglycemic potentials when compared to S-SP and SAF.S-SP,S-RCED,and SAF produced significant anti-inflammatory and anti-nociceptive activities against carrageenan-induced inflammatory,hyperalgesic and tactile diabetic-neuropathy models,respectively.S-SP,S-RCED,and SAF elevated serum catalase,reduced glutathione,and insulin serum levels,ameliorated lipid peroxidation and Hb A1 c levels,and histopathologically regenerated the pancreatic beta-cells.Combinations with CS showed more significant efficacy than the single component.Conclusion:The oxidative stress reduction,insulin secretagogue,and pancreatic beta-cells regeneration potentials might be responsible for the mechanism underlying the anti-diabetic,anti-inflammatory and anti-diabetic neuropathy activities.Thus,the cultivated Crocus sativus might be clinically useful for protecting against many serious-disorders.
