A New C-Glucosylflavone from Sorindeia juglandifolia

Abstract

Phytochemical investigation of the leaves of Sorindeia juglandifolia A. Rich. led to the isolation and identifi cation of a new C-glucosylfl avone, 2´´,6´´-di-O-acetyl-7-O-methyl vitexin (1), together with seven known compounds, 2´´-O-acetyl-7-O-methyl vitexin (2), mearnsitrin (3), robustafl avone (4), 3-O-galloyl catechin (5), tachioside (2-methoxy-benzene-1,4-diol-1- O-β-glucopyranoside) (6), 3β-O-D-glucopyranosyl-β-stigmasterol (7), and methyl gallate (8). The structures of 1 and the known compounds were established by IR, UV, MS, 1D, and 2D NMR spectra and by comparison with those of related compounds.
