Abstract: One new antifeedantal sesquiterpene(1) along with two known sesquiterpenes lα,6iβ-diacetoxy-9β-benzoyloxy-β-dihydroagarofuran(2) and lα-acetoxy-6β-9β-dibenzoyloxy-β-dihydroagarofuran(3) were isolated from the seed oil of Celastrus orbiculatus.The structure of the new sesquiterpene was elucidated as lα,2α,8β-triacetoxy-9β-cinnamoyloxyβ-dihydroagarofuran by UV,IR,MSand 1H NMR,13C NMR,COSY,13C-1 H COSY,HMBC .
