海南蕊木化学成分的研究──Ⅰ.根中单吲哚生物碱的分离与鉴定

Studies on the Chemical Components of Hainanruimu (Kopsia hainanensis)Ⅰ.Isolation and Identification of Monomeric Indole Alkaloids from Its Root

从海南蕊木Kopsiahainanensis根中分得8个化合物，经理化常数和光谱分析鉴定为单吲哚生物碱：coronaridine（Ⅰ）、heyneanine（Ⅱ）、tabersonine（Ⅲ）、11－methoxytaber－sonine（Ⅳ）、scandine（Ⅴ）、N－methoxycarbonyl－11，12－methylenedioxykopsinaline（Ⅵ）、kopsinine（Ⅶ）、N－methoxycarbonyl－12－methoxykopsinaline（Ⅷ）。其中化合物Ⅰ～Ⅴ均系首次从该属植物中分得。

From the total alkaloids of the root of Kopsia lainanensis Tsiang, eight compounds were isolatcd and identificd as coronaridine (Ⅰ), heyneaninc (Ⅱ), tabersonine (Ⅲ), 11-methoxytabersonine (Ⅳ), scandine (Ⅴ), N-methoxycarbonyl-11, 12-methylenedioxykopsinaline (Ⅵ), kopsinine (Ⅶ) and N-methoxycarbonyl-12-methoxykopsinaline (Ⅷ) by means of physical constants and spectral analysis
