(2-hydroxy-1-methyl 10,11-methylenedioxy noraporphine), a new alkaloid from the bark of Litsaealaeta has been established. N,O -Dimethylharnovine and glaucine were also isolated from the same source. C-2 hydroxy aporphines are characteristic of L. laeta . Two known alkaloids, dicentrinone and nordicentrine, have also been isolated from the leaves of L. salicifolia .
摘要 Laetine(2-羟基-1-甲基10,11-亚甲二氧基去甲啡肽)的结构已经确定,这是一种来自山苍子树皮的新生物碱。N,O-二甲基harnovine 和glaucine 也从同一来源中分离出来。C-2 羟基阿朴啡是 L. laeta 的特征。两种已知的生物碱,dicentrinone 和 nordicentrine,也已从 L. salicifolia 的叶子中分离出来。
