26-Nor-D:A-friedooleanane triterpenes from Phyllanthus watsonii

Two new unsaturated nor-triterpenes were isolated together with lupenyl palmitate, friedelin, epifriedelanol, glochidone, glochidonol, lupeol, lup-20(29)-en-1β,3β-diol, sitosterol and sitosterol-β-(d)-glucoside from the aerial parts of Phyllanthus watsonii, and their structures were established to b...
