title: Sesquiterpenoid and phenolic glucoside gallates from Lagerstroemia balansae.
abstract: Three new compounds, including a sesquiterpenoid glucoside gallate, 2 Z,4 E,1' R,2' S,4' R,6' S-dihydrophaseic acid 4'-O-(6''-O-galloyl)-β-D-glucopyranoside (1), two new phenolic glucoside gallates, 4-hydroxy-3,5-dimethoxybenzoic acid 4-O-(6'-O-galloyl)-β-D-glucopyranoside (2) and 3,4-dimethoxyphenol 1-O-(6'-O-galloyl)-β-D-glucopyranoside (3), together with eight known compounds (4-11), have been isolated from the stems of Lagerstroemia balansae. Their structures were elucidated on the basis of chemical and spectroscopic evidences.
