Angulatueoid G and H, Sesquiterpenes from the seeds of Celastrus angulatus

Abstract

Two new sesquiterpenes, angulatueoid G and H, were isolated from the seeds of Celastrus angulatus. Their structures were elucidated on the basis of spectroscopic data and chemical methods. Angulatueoid G showed insect antifeedant effect against Aulacophora femoralïs and Piutella xylostella.
