Abstract： 目的 对海南狗牙花中的吲哚类生物碱进行分离鉴定.方法 采用硅胶、Sephadex LH-20等柱色谱方法进行分离,NMR等波谱学方法进行结构鉴定.结果 从海南狗牙花中分离鉴定了7个吲哚类生物碱,分别为:海南狗牙花素(hainanervatasine, I)、海南狗牙花新(hainanervatacine, Ⅰ)、老刺木碱(vobasine, Ⅱ)、冠狗牙花定(coronaridine, Ⅳ)、3-羟基冠狗牙花定(3-hydroxyl coronaridine, Ⅴ)、3-(2-羰基-丙基)冠狗牙花碱[3-(2-oxopropyl) coronaridine, Ⅵ]、山辣椒胺(tabernamine, Ⅶ).结论 化合物Ⅰ、Ⅱ为新化合物,分别命名为海南狗牙花素(Ⅰ)、海南狗牙花新(Ⅱ),化合物Ⅳ、Ⅵ为首次从该植物中分离得到.
