PMID 17262948

Abstract

To investigate the chemical constituents of water-soluble part of stem of Nauclea officinalis. The compounds were isolated and purified by resins, silica gel, and Sephadex LH20 column chromatography repeatedly, and their structures were identified by spectral analysis. Seven compounds were isolated and identified as: naucleamide A-10-O-beta-D-glucopyranoside (I), 5-beta-carboxystrictosidin (II), sweroside (III), loganin (IV), 3,4-dimethoxyphenyl-beta-D-glucopyranoside (V), 3, 4, 5-trimethoxyphenyl-beta-D-glucopyranoside (VI), 2-phenethylrutinoside (VII). Compound I is a new indole alkaloid glucoside, compounds I-VII were isolated from this plant for the first time.
