The studies on the relation of structure-activity of 11 dihydroagarofuran compounds from Celastraceae Plants have been carried out in our laboratory. The results indicated that the hydroxy at C—4 was responsible for the antifeeding activity, that the isobutanoyloxy at C—12 might be an important poisonous active group, moreover, the β configuration was more active than the a configuration for a pair of isomers. The results also showed that the furancarbonyloxy at C—8, C—9 companied by isobutanoyloxy at C—12 might play an important role in narcotic activity.
