title: Chemical constituents of Prunella vulgaris.
abstract: Nine compounds were isolated from the spikes of Prunella vulgaris by various kinds of chromatography. Their structures were established on the basis of spectral analysis as polygalacerebroside (1), ursolic acid (2), β-amyrin (3), quercetin (4), quercetin-3-O-β-D-galactoside (5), α-spinasterol (6), stigmasterol (7), β-sitosterol (8), daucosterol (9). Compound 1 was isolated from this genus for the first time. Phytochemical investigation on the spikes of P. vulgaris provided chemical constituents diversity, which were performed to facilitate further development and utilization of P. vulgaris pharmaceutical resource.
