A new geranyl flavanone from Macaranga triloba

Abstract

A new geranyl flavanone, 2′-hydroxy-macarangaflavnone A (1), and a known 4′,7-dihydroxy-8-methylflavan were isolated from the leaves of Macaranga triloba (Euphorbiceae). The structure of 1 was elucidated based on spectroscopic methods, including 1D and 2D NMR analysis.
