高脱氧三尖杉酯碱是日本粗榧(Cephalotaxus harringtonia Var.harringtonia(Forbes)K.Koch)的枝叶进行愈伤组织培养时,在培养基中检测出的一种新的三尖杉酯类生物碱。Delfel等仅根据GLC和GC—MS数据,从生源观点判断,推测可能具有3表示的结构,但是,没有严格证明。我们认为这种推测是比较合理的,同时与从三尖杉属植物中分离得到的四种有明显抗癌活性的生物碱相似,它可能亦有抗癌活 High deoxygenated harringtonine is a new harringtonine organism detected in the culture medium of the callus of Cephalotaxus harringtonia Var.harringtonia (Forbes) K. Koch. Alkali. Based on the GLC and GC-MS data, Delfel et al., judging from the perspective of students, speculate that it may have a structure of 3, but there is no strict proof. We believe that this kind of speculation is reasonable, and similar to the four alkaloids with obvious anticancer activity isolated from the cephalocephalus, it may also have anti-cancer activity.
