摘要：

Two new unsaturated nor-triterpenes were isolated together with lupenyl palmitate, friedelin, epifriedelanol, glochidone, glochidonol, lupeol, lup-20(29)-en- 1beta,3beta-diol, sitosterol and sitosterol-beta-(D)-glucoside from the aerial parts of Phyllanthus watsonii, and their structures were established to be 26-nor-D: A-friedoolean-14-en-3-one and 26-nor-D:A-friedoolean-14-en-3beta-ol, respectively, on the basis of chemical, spectral and single crystal X-ray analyses.
