Abstract

From an acetone-water (3:2) extract of aerial parts of Thymus gobicus Czern. (31.1 g), compounds 1-8 were obtained using high-performance liquid chromatography. Based on spectroscopic data, the isolated compounds were identified as rosmarinic acid (1), monardic acid A (2), nepetoidin B (3), aromadendrin (4), apigenin (5), chrysoriol (6), apigenin 7-O-β-D-glucuronopyranoside (7), and apigenin 7-O-β-D-glucuronopyranoside methyl ester (8). Compound 2 was a (7R,8R)-diastereomer of lithospermic acid (2a). Although it was reported that the anti-allergic activity of lithospermic acid was higher than that of 2, the acetylcholine inhibitory activity of 2 was higher than that of lithospermic acid.
