石密的化学成分研究

Chemical Investigation on Alphonsea mollis Dum.

从番荔枝科植物石密的茎皮中分离和鉴定了一个氧化阿朴啡类生物碱——石密碱(1)和两个木脂素类化合物:(2R,3R)-2,3-二氢-2-(4-羟基-3-甲氧基苯基)-3-甲基-5-(E)-丙基苯并呋喃(2)和conocarpan(3)。其中石密碱为新化合物,化合物(2)和(3)为从番荔枝科植物中首次分得。

A novel oxoaporphine alkaloid, mollisine, and two neolignans, (2R, 3R)-2,3-dihydro-2-(4-hydrox-y-3-methoxy phenyl)-3-methyl-5-(E)-propenylbenzofuran and conocarpan were isolated from the bark of Atphonsea mollis Dum. The structures of these compounds were established on the basis of UV, IR, MS and NMR data.
