摘要：

The methanol extract of dried stem barks of Tripterygium wilfordii Hook hi. var regelii afforded two new triterpenes: 22-hydroxy-3, 19, 24-trinor-D:A-friedoolenane-1(10), 5, 7-triene-2-oic acid methyl ester, named regelone, and 3-methyl-23-ol-oxotingenol; anew diterpene-8 beta, 19-dihydroxy-3-oxopimar-15-ene; and three known triterpenes-3-methyl-22-beta, 23-diol-6-oxotingenol, tingenin B and cangoronin. Their structures were established on the basis of chemical and spectroscopic studies. (C) 1997 Elsevier Science Ltd. All rights reserved.
