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. [ABSTRACT FROM AUTHOR] |
