Abstract: Fifteen compounds included triterpenoids,sesquiterpenoids and steroids were isolated from the branches and leaves of Azadirachta indica cultivated in Yuanmou county of Yunnan Province.These compounds were identified as nimbin(1),6-deacetylnimbin(2),6-deacetylnimbinene(3),nimbinene(4),azadiradione(5),7-acetoxy-elema-1,3-dien-8-ol(6),1-naphthalenone(7),acarusnol(8),colvane-2β,9α-diol(9),ursolic acid(10),maslinic acid(11),2α-hydroxyoxyursolicacid(12),eriantic acid B(13),2α,3α,4β-trihydroxypregnan-16-one(14),2β,3β,4β-trihydroxypregnan-16-one(15)by means of NMR and MS methods.Compounds 6-15 were isolated for the first time from this species.
