 | Hazard Information | Back Directory |  | [Uses] 
 Kurarinol is a flavanone found in the root of Sophora flavescens. Kurarinol is a competitive tyrosinase inhibitor, with IC50 of 0.1 μM for mushroom tyrosinase[1].
 |  | [Definition] 
 ChEBI: A trihydroxyflavanone that is (2S)-flavanone substituted by hydroxy groups at positions 7, 2' and 4' , a methoxy group at position 5 and a (2S)-5-hydroxy-5-methyl-2-(prop-1-en-2-yl)hexyl group at position 8 respectively.
