Extractive yield was found highest in Aq. (5.556 %w/w) extract, followed by EtOAc (0.705 %w/w) and n-hexane extracts (0.071 %w/w), respectively. The extracts were evaluated on ABTS•+ scavenging and antityrosinase activities. Total phenolic content was determined by Folin Ciocalteau method. HPLC was used for quantification of phenolics in extracts. The EtOAc extract was the most potent antioxidant extract with an IC50 of 2.915 ± 0.022 ppm, which was significantly better than ascorbic acid (IC50 = 6.288 ± 0.098). In addition, the EtOAc extract posed the strongest tyrosinase inhibitory effect (89.010 ± 0.420 %). Therefore, it was evaluated on IC50 (430.838 ± 0.568 ppm). However, it was less active than kojic acid (IC50 = 38.984 ± 0.514 ppm).Total phenolic content was found highest in the EtOAc extract (45.500 ± 0.866 g GAE/ 100 g crude extract). Total phenolic content was related with antioxidant (r = 0.955) and antityrosinase activities (r = 0.844). The EtOAc extract was non- cytotoxic in Vero cells at 50 ppm. HPLC analysis found ferulic acid (3.235 ± 0.023 g/ kg), gallic acid (2.434 ± 0.044 g/ kg), rosmarinic acid (1.743 ± 0.151g/ kg), caffeic acid (1.267 ± 0.218 g/ kg), kojic acid (0.932 ± 0.023 g/ kg), chlorogenic acid (0.388 ± 0.032 g/ kg) and quercetin (0.885 ± 0.156 g/ kg) highest in the EtOAc extract. Therefore, the EtOAc extract was further Thesis (M.Sc.) -- Cosmetic Science, School of Cosmetic Science.
