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 .

Mushrooms are widely available around the world and have various nutritional as well as therapeutic values. Many Asian cultures believe that medicinal mushrooms can prolong life and improve vitality. This study aims to characterize the phytochemical and polysaccharide content, mainly β-glucan content, of mycelial biomass and fruiting bodies collected from the Himalayan region, particularly Uttarakhand. Through molecular analysis of the LSU F/R-rDNA fragment sequence and phylogenetic analysis, the strain was identified as Trametes sp. We performed screening of phytochemicals and polysaccharides in mushroom and biomass extracts using high-performance liquid chromatography (HPLC) and a PC-based UV-Vis spectrophotometer. The macrofungal biomass was found to be high in saponin, anthraquinone, total phenolic, flavonoid, and β-glucan content. In biomass extract, we observed a high level of saponin (70.6µg/mL), anthraquinone (14.5µg/mL), total phenolic (12.45 µg/mL), and flavonoid (9.500 µg/mL) content. Furthermore, we examined the contents of alkaloids, tannins, terpenoids, and sterols in the biomass and mushroom extracts; the concentration of these compounds in the ethanol extract tested was minimal. We also looked for antioxidant activity, which is determined in terms of the IC50 value. Trametes sp. mushroom extract exhibits higher DPPH radical scavenging activity (62.9% at 0.5 mg/mL) than biomass extract (59.19% at 0.5 mg/mL). We also analyzed β-glucan in Trametes sp. from both mushroom and biomass extracts. The biomass extract showed a higher β-glucan content of 1.713 mg/mL than the mushroom extract, which is 1.671 mg/mL. Furthermore, β-glucan analysis was confirmed by the Megazyme β-glucan assay kit from both biomass and mushroom extract of Trametes sp. β-glucans have a promising future in cancer treatment as adjuncts to conventional medicines. Producing pure β-glucans for the market is challenging because 90–95% of β glucan sold nowadays is thought to be manipulated or counterfeit. The present study supports the recommendation of Trametes sp. as rich in β-glucan, protein, phytochemicals, and antioxidant activities that help individuals with cancer, diabetes, obesity, etc.

“…The extracted samples are a moderate source of lipids and terpenoids in hexane, petroleum ether, ethyl acetate and chloroform fractions except for the aqueous fraction where it was found absent. Since bioactive compounds play a crucial role in the living organism and their importance has been discussed in many research articles in detail (Anjana et al, 2016). More than 50 dietary mushrooms and several hundred fungal species have natural products in a significant amount.…”

S ynthetic chemicals are commonly used to control agricultural pests and plant pathogens in every part of the world (Whipps and Lumsden, 2001). Worldwide loss in crop production is currently 15 % due to pests (Maxmen, 2013). To overcome this, a large amount of pesticide is used. It is clear that these chemicals are persistent in the environment and their residues can end up in our food chain (Montesinos, 2003). Uncontrolled use of these chemicals results in resistance to pesticides, toxicity to humans, animals, and plants and is thus deemed environmentally unacceptable (Bhattacharjee and Dey, 2014). This situation led scientists to look for new antimicrobial substances from different sources to be used as novel Abstract | Effect of substrate supplemented with a medicinal plant (Berberis lycium L) was documented on days to 50% colonization, days to 100% colonization, yield per bag and % bio-efficacy of Pleurotus eryngii. It was found that maximum 20 and 34 days were taken by 50% and 100% colonization, respectively on 25% supplemented B. lycium substrate compared to control treatment (17 days). The yield and bio-efficacy of mushroom was observed around 596.7 g per bag and 99% respectively at 25% supplemented B. lycium substrate. The P. eryngii mass was extracted with different solvents and showed promising results for the number of phytochemicals. Alkaloids were present in all fractions except n-hexane and petroleum ether while tannins were present in all the fractions. Flavonoids, lipids, terpenoids and glycosides were present in extracts at moderate to high concentrations. Methanolic fraction of mushroom proved to be bactericidal with highest % inhibition (65, 36 and 75 %) recorded at 25 mg/L concentration against all the three bacterial strains i.e., E. coli, Staphylococcus aureus and Xanthomonas sp., respectively. Maximum % inhibition (about 50%) was recorded at 25 mg/L concentration against all the three fungal species (Penicillium claviforme, Aspergillus flavus and Fusarium sp.). Methanolic extract of P. eryngii showed increasing % mortality against red flour beetle (Tribolium castaneum) in methanolic extract with increasing concentration after 24 and 48 h exposure time. Maximum mortality (100%) was noticed at 300 mg/L after 40 h exposure time. Hence, methanolic extract of P. eryngii can be used as a natural pesticide, especially in stored grains.
