摘要
Methanol extract of Stellera chamaejasme L wasassessed for antitumor activity by an antitumor activebioassay against murine leukemia P388 in vivo. Thebioassay-directed separation of the extract furnishedseven diterpene compounds (stellerarin, stelleramacrin,gnidimacrin, pimelea factor P2, subtoxin, huratoxin,simplexin ) and two biflavanone compounds (neochemae-jasmin A and B). Among them, gnidimacrin, stellerarinand stelleramacrin (a novel compound) were found tohave high antitumor and cytotoxic activities against P388,L1210 and K562 in vivo and in vitro. The results suggestedthat the diterpene compounds were the potent anti-tumor principles of Stellera chamaejame L
