Abstract

Abstract: A new flavonoid, 8-(3-hydroxymethyl-2-butenyl)-5, 7, 2′, 4′-tetrahydroxyflavanone (1 ), along with seven known compounds, (2R)-3α, 7, 4′-Trihydroxy -5-methoxy-8-prenylflavanone (2 ), (2R)-3β, 7, 4′- Trihydroxy-5-methoxy-8-prenylflavanone (3 ), 3, 7-dihydroxycoumarin (4 ), Shandougenines B (5 ), Specionin (6 ), Kushenol N (7 ) and Kushenol I (8 ) were isolated from the roots of Sophora flavescens . Among them, Compound5 was isolated from Leguminous plants, and compounds 4 and 6 were isolated from Sophora flavescens for the first time. Their structures were elucidated by the aid of NMR, HRMS, HMBC and CD spectroscopic methods. Abstract :
