Abstract:
Cang Er Zhi (Fructus Xanthii), from the fruit of Xanthium sibiricum Patr., is a commonly used traditional Chinese medicine for chronic rhinitis with a little toxicity. In order to prove the material of X. sibiricum that produce bioactivities, it is necessary to investigate its chemical constituents. Solvent extraction, repeated column chromatography on silica, C-18 and MCI were used for isolating compounds from the 80% MeOH/H2O extract of X. sibiricum, and MS and NMR spectral evidences were used for structure elucidation. Seven compounds were isolated: Ferulic acid (1), caffeic acid (2), chlorogenic acid (3), 4-O-caffeoyl quinic acid methyl ester (4), N-(1′-D-deoxyxylitolyl)-6,7-dimethyl-1,4- dihydro-2,3-quinoxalinedione (5), caffeic acid choline ester (6) and dihydrophaseic acid sodium salt 4′-O-β-D-glucopyranoside (7). Among of them, compounds 4~7 were isolated from X. sibiricum for the first time. Fig1, Ref 10
