Lipophilic components from Fructus Viticis Negundo and their anti-tumor activities

Two new triterpenoids, (24R/S)-24-hydroxy-3α 10α-epoxy-9-eip-cucurbita-25-ene (1a, b), as well as six known compounds (3-8), were isolated from the extraction of Fructus Viticis Negundo. Their structures were established on the basis of spectral analysis. In addition, all the compounds were tested for inhibitory effect against K-562 and A-549 cell lines.
