| Abstract: | 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. |
