1H-Indole-3-acetonitrile glycoside, phenolic and other compounds from Stixis suaveolens

Abstract

From the methanol extract of the Stixis suaveolen sleaves, 1H-lndole-3-acetonitrile 4-0-β-i)-glucopyranoside (1), β-adenosine (2), β-adenosine (3), 1-O-syrinoyl-β-D-glucopyranoside (4), 2,6-dimethoxy-p-hydroquinone 1-0-β-D-glucopyranoside (5), icariside B5 (6) were isolated by various chromatographic methods. The chemical structures of these compounds were elucidated by HRESI-MS, 1D and 2D NMR spectra and by comparison with data reported in the literature. This is the first report of these compounds from Stixis suaveolens.
