Hence, thermal stability of substance is necessary in course of its drying to acertain the degree of temperature it will be subjected to. In this research, sclerotium of Pleurotus tuberregium is subjected to thermogravimetric analysis, differential thermal analysis and differential scanning calorimetry. Both thermogravimetric analysis and differential thermal analysis were conducted from ambient temperature to 1000°C at a rate of 20°C/min constant heating rate, while differential scanning calorimetry was conducted from ambient temperature to 400°C at a rate of 10°C/min constant heating rate. Besides, the oxides contents of sclerotium of Pleurotus tuberregium were determined using x-ray fluorescence analysis and the mircostruture was determined with scanning electron microscopy. It was discovered that complete dehydration of the sample ended at about 110.38°C and oxidation reaction occurred between 233.42°C to 373.82°C with release of heat by the sample. Sclerotium of Pleurotus tuber-regium is thermal stable up to 233.42°C with decompostion of steroid which is its second major component at about 400°C to 480°C. The x-ray fluorescence analysis of sclerotium of Pleurotus tuber-regium revealed that Na<sub>2</sub>O, MgO, SiO<sub>2</sub>, Al<sub>2</sub>O<sub>3</sub>, and Fe<sub>2</sub>O<sub>3</sub> are the major compound and SEM analysis showed that it is a solid with amorphous structure having some fibrous skeleton. This study revealed that sclerotium of Pleurotus tuberregium could be dried to minimal moisture content without the deterioration of its nutritional and medinicnal properties.展开更多

A large number of clinical studies have reported and proven concern of cancer patients. Here we have also reported recent studies on the biochemical and cellular mechanisms of Traditional Medicine (TM). Nowadays, Chemotherapy and surgery are standard methods for treatment of cancer, but still it’s not been fully successful. Some progress has been made in cancer diagnosis and treatment, but high incidence rate of cancer and low survival rate of patient are still being reported worldwide. Since ancient times, a number of traditional medicines known as Ayurveda, Siddha, Unani, Iranian, Chinese, Korean, acupuncture, Muti, Ifa, and African medicine are widely used for therapeutic purposes and are becoming popular as Traditional Medicine (TM). It has been reported that plants synthesize plethora of “secondary metabolites” or “phytochemicals”, proven to possess anti-mutagenic and anti-cancer properties in many research studies. There are many possibilities for further organized research for screening of medicinal plants for their potential and efficacy against chronic diseases such as a cancer and other inflammatory diseases. Therefore, researcher’s interest should be in identification and standardization of new anti-cancer drug with low side effects and greater efficacy, that is easily acceptable in medical community and which may overcome the challenges in present and future cancer therapy. This review explores therapeutic value of certain bio-active principals of plant which could serve as potential pharmacologically active drug for treatment of cancer in future.展开更多

Among 86 fungal endophytes isolated from 15 medicinal plants Aspergillus terreus-AFl04S, Aspergillusegypticus-HT166S and Penicillium sp.-CC200 exhibited strong pancreatic amylase inhibitory potential were selected. Endophyteswere subjected to ethyl acetate extraction and tested for a-amylase inhibition, in order to assess and evaluate their inhibitory potentialon pancreatic a-amylase. Analysis showed concentration dependent enzyme inhibition up to 83% with half inhibition （IC50） valuesfor less 25 mg.mL1, which is lower than acarbose as control. It was observed 3-fold increasing of Vmax and maintenance Km atcontrol level in the presence of extracts A. terreus-AFl04S and Penicillium sp.-CC200, while in presence of extract A.egypticus-HT166S Km was doubled, and Vmax was maintained at the control level. Kinetic studies allow proposing the competitivemode of a-amylase inhibition by extracts A. egypticus-HT166S and uncompetitive inhibition by extracts A, terreus-AFl04S andPenicillium sp.-CC200.展开更多
