Abstract
Aralia armata is one of the common herb species in mountainous areas, especially in the northern mountainous areas of Vietnam, which has potential in pharmaceutical and agricultural industries. Herein, we report that an oleanolic acid saponin named pseudogisenoside RT1 methyl ester (A) was isolated from the roots of the species Aralia armata. The fractionated extracts of dichloromethane, ethyl acetate, water and compound A were investigated for their molluscicidal effects, specifically on Pomacea canaliculata. The tests showed that the extracts and compound A from A. armata roots had good activity against P. canaliculata snail. In particular, compound A had a Lethal concentration of 50 (LC50) value of 16.443 µg/mL.
