Studies on the constituents of Goat's Rue (Galega officinalis L.).

Abstract

A new saponin, 3-Ο- [β-D-glucopyranosyl (1-02) β-D- glucuronopyranosyl] soyasapogenol B (XII) has been isolated from the herb of goat's rue (Galega officinalis L.), together with phytosterol (I), medicagol methyl ether (IV), medicagol (VI), phytosterol-β-D- glucoside (VIII), and allantoin (XI). The structures of the compounds were derermined on the basis of chemical and spectral evidence. This is the first time that I, IV, VI, VIII and XI have been isolated from this plant.
