摘要
目的 研究滇钩藤 (UncariayunnanensisHsia .C .C)根的化学成分。 方法 运用各种色谱技术进行分离 ,用IR ,MS ,1HNMR ,13CNMR ,2DNMR等光谱技术鉴定化合物。结果 得到 7个化合物 ,分别鉴定为 :3β ,6 β,19α 三羟基乌苏酸 (I) ,2 3 , 去甲基 2 4烯 3β,6 β ,19α 乌苏酸 (II) ,6 β,19α 二羟基 乌苏酸 3 酮 (III) ,齐墩果酸 (IV) ,5 ,7,3′,4′ 四羟基 黄烷 3 醇 (V) ,β 育亨宾 (VI)和滇钩藤碱I(VII)。 结论 VII为新化合物 。
AIM To research the chemical constituents from dried roots of Uncaria yunanensis Hsia.C.C. METHODS Modern chromatography was used to isolate chemical components. Their structure were identified by spectral analysis. RESULTS Seven compounds were isolated and identified as 3β,6β,19α trihydroxyurs 12 en 28 oic acid (I), 23 nor 24 esomethylene 3β,6β 19α trihydroxyurs 12 en 28 oic acid (II), 3 oxo 6β,19α dihydroxyurs 12 en 28 oic acid (III), oleanic acid (IV), 5,7,3′,4′ tetrahydroxy flavan 3 ol (V), β yohimbine (VI) and diangoutengjian I (VII). CONCLUSION All of the above compounds were isolated for the first time from the root of this plant. Among them, compound VII is a new one.
