[A novel triterpenoid saponin from Prunella vulgaris].
To study the constituents of the Prunella vulgaris L, the constituents were isolated by various column chromatography and the structures were identified on the basis of chemical and spectral analysis. One saponin compound (I) and one flavone glycoside compound (II) were obtained from Prunella vulgaris L. Their structures were elucidated as 16-oxo-17-demethyl-3beta,24-dihydroxylolean-12-en-3-O-beta-D-glucuronoside (I), and acacetin-7-O-beta-D-glucopyranoside (II). Compound I is a novel triterpenoid saponin and named as prunelloside A. Compound II was obtained for the first time from the Prunella genus.
