1.14.18.1 | kojic acid | inhibitory effects with kojic acid | Agaricus bisporus | |
1.14.18.1 | kuraridinol | prenylated flavonoid from Sophora flavescens, isolated from the EtOAc fraction, inhibitory effects on tyrosinase and melanin synthesis. Inhibitory activity 20times more potent than that of the positive control, kojic acid. Kuraridinol is a chalcone compound belonging to the prenylated flavonoids | Agaricus bisporus | |
1.14.18.1 | kurarinol | prenylated flavonoid from Sophora flavescens, isolated from the EtOAc fraction, inhibitory effects on tyrosinase and melanin synthesis. Kurarinol is a prenylated flavanone and an effective inhibitor of alpha-glucosidase, beta-amylase, and cGMP phosphodiesterase-5, and also inhibits diacylglycerol acyltransferase activity | Agaricus bisporus | |
1.14.18.1 | additional information | compounds from Sophora flavescens are further tested for their inhibitory effects on melanogenesis in B16 melanoma cells. MeOH extract fraction, CH2Cl2 fraction, EtOAc fraction and, n-BuOH fraction from Sophora flavescens inhibit L-tyrosine oxidation catalyzed by tyrosinase in concentration dependent manner. EtOAc fraction has more potent inhibitory activity than the other fractions | Agaricus bisporus | |
1.14.18.1 | trifolirhizin | prenylated flavonoid from Sophora flavescens, isolated from the EtOAc fraction, inhibitory effects on tyrosinase and melanin synthesis | Agaricus bisporus |
