5,7-Dihydroxy-3,6-Dimethoxy-3/,4'-Methylendioxyflavone

Abstract

A new flavonoid derivativr, namely 5,7-dihydroxy-3,6-dimethoxy-3/,4/-methylenedioxy flavone (1), was isolated from the leaves of Melicope glabra (Blume) T.G. Hartley. The structure of 1 was elucidated based on their UV, IR, HRESIMS, and 1D and 2D NMR spectral data.
