目的:测定海地瓜脑苷脂组成。方法:样品经10%盐酸-甲醇溶液水解,采用气相色谱-质谱(GC-MS)联用技术对已分离纯化的海地瓜脑苷脂样品进行分析测定。结果:分别分析测定了3种海地瓜脑苷脂(AMC-1、AMC-2、AMC-3)的脂肪酸、长链碱和糖基组成:脂肪酸主要为饱和的、单不饱和的和含羟基的脂肪酸,长链碱有二羟基和三羟基2种结构,糖基主要为葡萄糖。结论:通过GC-MS法分析海地瓜脑苷脂,为脑苷脂类化合物的定性分析和进一步结构研究提供了一定的依据。
OBJECTIVE: To determine the composition of melilopsin in Haiti. Methods: The samples were hydrolyzed with 10% hydrochloric acid-methanol solution and analyzed by gas chromatography-mass spectrometry (GC-MS). Results: The fatty acids, long-chain bases and glycosyl groups of three species of melittin (AMC-1, AMC-2 and AMC-3) were analyzed and determined respectively. The fatty acids were mainly saturated, monounsaturated and hydroxyl group Of the fatty acids, long-chain base with two hydroxyl and trihydroxy two kinds of structure, mainly glucose glucose. Conclusion: GC-MS analysis of brachiaridin provides a basis for the qualitative analysis and further structural studies of cerebroside compounds.
