C -Prenylflavonoids from Derris heyneana

Abstract

2′,4′-Dihydroxy-3′-(3-methylbut-2-enyl)-4-methoxychalcone (1) and three known C-prenylflavonoids, namely, lupinifolin (flemichin B), hiravanone, and derrubone were isolated from the leaves of Derris heyneana (Febaceae). The structures were established by 2D NMR analysis.
