White variety of Auricularia fuscosuccinea is a newly cultivated gelatinous mushrooms which is found only in Taiwan. In this study, total phenolic and total flavonoid content of methanol extract of white variety of A. fuscosuccinea was estimated, and in vitro antioxidant properties and antioxidant enzyme activities were also evaluated. When compared with two other common gelatinous mushrooms, A. polytricha and Tremella fuciformis, white variety of A. fuscosuccinea had the highest total phenolic [7.88 mg gallic acid equivalents (GAE)/g] and total flavonoid [1.60 mg quercetin equivalents (QE)/g]. Among all methanol extracts analyzed, white variety of A. fuscosuccinea had the lowest EC 50 value on reducing g power (0.305 mg/ml) and scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical (0.150 mg/ml) had the highest total sugars [44.73 mg dextrose equivalents (DEX)/g] and the lowest EC 50 value on chelating effect on ferrous ions (0.427 mg/ml). The methanol extracts from white variety of A. fuscosuccinea possessed the highest superoxide dismutase activity (2.10 U/mg) and total antioxidant capacity (2.26 mM/g). The glutathione reductase activity (7.97 U/g) of A. polytricha was the highest. The analyses of the antioxidant contents phenolic compounds are mainly responsible for the antioxidant effect of gelatinous mushrooms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
