中药巴戟天为茜草科植物巴戟天(Morinda officinalis How)的根。主产广东。中医用于补肾阳、壮筋骨、祛风湿。其化学成分研究很少,只最近报道(1)自根中得到β-谷甾醇、甲基异茜草素、甲基异茜草素1-甲醚(Ⅱa)一个未鉴定的蒽醌和一单糖混合物。我们自巴戟天根的乙醇提取物中分得三种单体,根据物理常数和光谱数据晶Ⅰ鉴定为β-谷甾醇(β-sitosterol),晶Ⅱ为水晶兰甙(monotropein),晶Ⅲ为四乙酰车叶草甙(asperuloside tetraacetare)。后两者为
Chinese medicine Morinda officinalis plants Morinda officinalis (Morinda officinalis How) roots. Main production in Guangdong. Chinese medicine for kidney yang, strong bones, rheumatism. The chemical composition of the study few, only recently reported (1) from the root to get β-sitosterol, methyl heterophylla, methyl heterophylla 1-methyl ether (Ⅱ a) an unidentified anthraquinone and a monosaccharide mixture. We isolated three kinds of monomers from the ethanolic extract of Morinda officinalis, identified as β-sitosterol by crystal I and monotropein by crystal I according to the physical constants and spectral data Is tetraacetyl carrageenan (asperuloside tetraacetare). The latter two are
