Abstract: Celastrus angulatus Max. is a singnificant insecticidal plant dispersed widely over our country. For its antifeeding value , the roots have been stuied chemically as a result of some new sesquiterpene polyster[1,2].The bioactive tests of its seed oil showed highly antifeedant effect on pieris rapae, Aulacophora femoralis,Henosepilachna,Vigintioctopunctata, Locastra muscosalis, colaphllus bowringi and Calospilos suspecta[3,4].In this continuing communication we report eight new sesquiterpene polyesters (1-8)isolated from the seeds of the plant by means of distrbution and chromatography. Their structuret have been characterized by spectroscopic and chemical methods and relate to dihydro-β-agarofuran skeleton as follows.

Key words: Celastrus angulatus
