A new compound (1) named as winchic acid and eight known ones were isolated from the stem barks of Winchia calophylla A. DC. (collected in Xishuangbanna, Yunnan Province of China). The new compound 1 was identified as 3β-hydroxy-27-(4-hydroxy –3-methoxy-E-cinnamoyloxy)-lup-20(29)-en-28-oic acid on the basis of 1D and 2D NMR experiments. The eight known compounds were determined to be lupenone, lupenyl acetate, betulinic acid, α amyrin acetate, ursolic acid, ptiloepoxide, β-amyrin and cycloeucalenol, respectively.
