Holigarna arnottiana Hook.f belongs to Anacardiaceae. In this study, we use ethanolic extract of H.arnottiana, by hot and cold extraction method to compare the antioxidant potential. DPPH scavenging activity and Ferric Reducing Antioxidant Potential (FRAP) were analysed (10μg-100μg). Methanolic extract obtained by cold extraction showed higher activity (64.10±0.23 at 100 μg for FRAP assay and 0.425±0.21 at 100 μg for DPPH activity) in both DPPH scavenging activity and ferric reducing antioxidant potential. The test was conducted against the standard BHA and there was an increased potential with respect to the extract concentration.

DPPH scavenging activity and Ferric Reducing Antioxidant Potential (FRAP) were analysed (10μg-100μg). Methanolic extract obtained by cold extraction showed higher activity (64.10±0.23 at 100 μg for FRAP assay and 0.425±0.21 at 100 μg for DPPH activity) in both DPPH scavenging activity and ferric reducing antioxidant potential. The test was conducted against the standard BHA and there was an increased potential with respect to the extract concentration.
