“…As potent bio-accumulators, the chemical and nutritional profile of mushrooms is often a function of the type of substrate on which they are cultivated 23,29 . The gas chromatography analysis of the mushroom samples revealed the presence of a number of bioactive compounds, albeit in different concentrations.…”

Background and Objective: Nature-derived products are finding increased application for therapeutic purposes. Apart from their use as food, mushrooms have been reported in various research to contain bioactive compounds with medicinal capabilities. This study evaluated the in vitro antidiabetic and antioxidant activities of an aqueous extract of Pleurotus ostreatus (mushroom) cultivated on rice bran/sawdust (RB/SD, 70:30 w/w) mixture and sawdust (SD) substrates. Materials and Methods: Pleurotus ostreatus was cultivated on two different substrates followed by aqueous extraction of mature mushrooms.In vitro antidiabetic, (α-amylase and α-glucosidase inhibition) and antioxidant (DPPH radical-scavenging assay and ferric reducing power (FRAP) activities were done using standard methods. Results were analyzed using IBM Statistical Product and Service Solutions (SPSS) software, version 23 and the significance level was established at p<0.05. Results: The extracts showed a concentration-dependent inhibitory effect on α-amylase and α-glucosidase activities in vitro. There was a stronger inhibition of α-amylase activity by the RB/SD sample when compared to SD and a weaker inhibitory effect of the RB/SD sample on α-glucosidase activity when compared to SD. Again, the samples showed a concentration-dependent antioxidant effect with increased DPPH-scavenging activity and FRAP observed with the SD sample compared to the RB/SD sample. The GC-FID analysis of the P. ostreatus samples also revealed the presence of a number of bioactive compounds in different concentrations. Conclusion: These results highlight the effect of cultivation substrate on the potential therapeutic effect of mushrooms the aqueous extract of P. ostreatus could be a promising raw material for the development of anti-diabetes therapeutics.

The oyster mushroom (Pleurotus ostreatus) is a culinary mushroom. Mushrooms are considered a potential source of many essential nutrients and therapeutic bioactive compounds. Pleurotus ostreatus is a macro fungus that belongs to the class Basidiomycetes and the family Pleurotaceae, known as the oyster mushroom. It is the most important commercially cultivated mushroom in the world. Mushroom contains rich nutrients such as proteins, carbohydrates, vitamins, amino acids, lipids and fibers. It is used as food and medicine. Mushroom contains more bioactive compounds such as peptides, polysaccharides, liposaccharides, glycoprotein, lectin, triterpenoid, fatty acids, essential amino acids and nucleosides. They are used traditionally as a medicine for different diseases. These mushrooms have been reported to be antioxidant, anticancer, antimicrobial, antiinflammatory, antidiabetic, antihypertensive, antihypercholesterolemic, antiatherogenic, anti-hyperglycemic and immunomodulating. This review gives information on the traditional uses, chemical composition and nutritional benefits of oyster mushrooms. These studies reveal that Pleurotus ostreatus is a source of medicinally active compounds with various pharmacological effects. These studies will be helpful to create interest in Pleurotus ostreatus and may be useful in developing a new reaction for further research. INTRODUCTION:The oyster mushroom was firstly described in 1775 by Dutch naturalist Nikolaus Joseph Freiherr von Jacquin (1727-1817). In 1871 German mycologist Paul Kummer transferred the Oyster mushroom to the genus Pleurotus. (A new genus that Kummer himself had defined in 1971), given its currently accepted name Pleurotus Ostreatus. It has long been cultivated in Asia, Japan, and the Chinese 1 .
