Abstract

To study the chemical constituents from Radix Boehmeriae. Compounds were isolated by various column chromatographies with silica gel, their structures were elucidated by spectral analysis and chemical evidence. Eight compounds were isolated and their structures were identified as emodin (1), emodin-8-O-beta-glucopyranoside (2), physcion (3), polydatin (4), catechin (5), epicatechin (6), potassium nitrate (7), sitosterol (8). Among these compounds, 3 -7 are isolated from Radix Boehmeriae for the first time.
