Kaempferol (1), quercetin (2), quercitrin (3), rutin (4), hesperetin (5), and hesperidin (6) used in this study were flavonoids having a phenylchroman skeleton as the basic structure. Antioxidant ability, skin-whitening effect, and histamine-release suppressing effect were examined as their new physiological activities in this study. As a result, in DPPH radical scavenging effect test, which evaluates activity of antioxidant ability, high scavenging effect (90-96％) was observed in (1), (2), and (4). In skin-whitening effect test, it was clarified that (1) and (2) exert higher tyrosinase inhibition activity (42-60) than that of commercially available arbutin (7.3). In toxicity test using human alveolar epithelial cells (in vitro), meanwhile, no difference from control was observe in (3), (4), (5), and (6) at 100 μM concentration, and it was reasoned that there are no considerable toxicity., application/pdf},
