摘要	Five compounds were isolated from the EtOH extraction of the stem of Amoora dasyclada (How et T. Chen) C. Y. Wu (Meliaceae). On the basis of spectroscopic methods, their structures were elucidated as 24, 25-epoxy-tirucall-7-ene-3, 23-dione (1), 24, 25, 26, 27-tetranortirucall-7-ene-3-oxo-23 (21)-lactone (2), taraxerone (3), taraxerol (4) and P-sitosterol (5). Among them, compound I was a new triterpenoid, compounds 3-5 were firstly obtained from this plant; compound 2, an tetra nortriterpenoid, was firstly isolated from natural sources, and its NMR data were assigned for the first time. Moreover, the Delta(7)-bond and the Me-14 in compound 2 were never changed, which has never been found in other tetranortriterpenoids. And the biosynthetic pathway of tetra nortriterpenoid was further discussed.
