A 4-methyl-7-hydroxyphthalide glycoside and other constituents from Quillaja saponaria molina

Phytochemistry. 1995 Nov;40(4):1313-5. doi: 10.1016/0031-9422(95)00496-t.

Abstract

A so far unknown 4-methyl-7-hydroxyphthalideglycoside has been isolated from the methanol extract of the bark of Quillaja saponaria molina. Its structure has been established from NMR experiments as 7-O(-)[beta-glucopyranosyl-(1-->6)-beta-arabinopyranosyl]-7-hydrox y-4-methy l -1[3H]-isobenzofuranone. Two known compounds, 3,4,5-trimethoxyphenyl-beta-D-glucopyranoside and lyoniresinol-3 alpha-O-beta-D-glycopyranoside were also identified.
