[摘要]：The phytochemical investigation of Dipteronia dyeriana (Aceraceae) resulted in the isolation and identification of five new triterpenoid ester saponins, dipterosides A-E (1-5). Their structures were elucidated by spectroscopic methods and chemical evidence. The inhibitory activities of these compounds against human leukemia K562 and human hepatoma HepG2 cells were also evaluated.
