Abstract

Total phenolics, condensed tannins, ascorbic acid, total antioxidant activity, reducing power, ferric reducing antioxidant power, radical scavenging activity (RSA) on DPPH & ABTS and metal chelating activity of methanolic and aqueous extract from cap and stipe of Lentinula edodes have been evaluated. Different extracts contained 2.40-5.60 mg gallic acid equivalent of phenolics, 1.23-3.26 mg catechins equivalent of condensed tannins, and 2.31–11.96 mg ascorbic acid per gram of extract. Aqueous extract from cap contained higher phenolics, condensed tannins, ascorbic acid, RSA on DPPH and ABTS, reducing power, and metal chelating activity. We found that this mushroom species present antioxidant potential especially higher for cap indicating that the cap is the material that most contributes to the antioxidant activity.
