Abstract

A new ursolic-type acid named triptotriterpenic acid C was obtained from the total glycosides extracted from the root of Tripterygium wilfordii Hook.f. Its structure was inferred from chemical reaction, IR, 1HNMR, 13CNMR and MS spectral data. The structure and stereochemistry of this compound was confirmed to be 3 beta,22 alpha-dihydroxy-delta 12-ursene-30-oic acid by X-ray crystallo-diffraction analysis of its methyl ester.
