简介:甲醇摘录ofStellerachamaejasmeL被antitumor为antitumor活动估计对鼠科的白血病P388invivo的活跃生物鉴定。摘录的bioassay-directcd分离供应了七diterpene混合物(stellerarin,stelleramacrin,gnidimacrin,pimelea因素P2,subtoxin,huratoxin,simplexin)并且二biflavanone混合物(neochemae茉莉属A和B)。在他们之中,gnidimacrin,stellerarin和stelleramacrin(新奇混合物)被发现对P388,L1210和K562invivoandinvitro有高antitumor和细胞毒素的活动。结果建议diterpene混合物是有势力antitumorprinciplesofStellerachamaejasmeL。
