Maackia amurensis Rupr.

Two compounds with strongly insecticidal and fungicidal activity, Kurarinone and Sophoraflavanone G , were isolated from Sophora flavescens Ait under the direction of bioassay, and comfirmed by UV, IR, MS and NMR.

From n-butyl alcohol fraction of Sophora flavescens,the tyrosinase inhibitory constituents were isolated and identified as flavonoids,sophoraflavanone G and kurarinone,respectively.
