    Evaluation of mycelial nutrients, bioactive compounds, and antioxidants of five Himalayan entomopathogenic ascomyceteous fungi from India
    (Begell House Inc., 2015) Sharma, S.K.; Gautam, N.; Atri, N.S.
    In this study, using standard methods, mycelial nutrients, bioactive compounds, and antioxidants were analyzed for the first time for five fungal species: Isaria sinclairii (Berk.) Lloyd, I. tenuipes Peck, I. japonica Yasuda, I. farinosa (Holmsk) Fr. and Cordyceps tuberculata (Lebert) Maire. All of these species were low in fat content and rich in protein, fiber, ash, and carbohydrates. Mineral elements (Fe, Mg, Cu, Mn, and Ca) were detected in appreciable amounts. All three types of fatty acids (saturated, monounsaturated, and polyunsaturated) as well as bioactive compounds (ascorbic acid, ?-carotene, lycopene, phenolic compounds, and polysaccharides) were detected for each species. The investigated species showed high ferric-reducing antioxidant power as well as 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity. Although differences were observed in the values of each species, each species showed richness in one or more components. ? 2015 Begell House, Inc.
