摘要
从菊科麻花头属植物华麻花头(Serratula chinensisS.Moore)根中分离得一组神经酰胺类化合物,经光谱和化学方法分析,鉴定为(2S,3S,4R,8E)-8,9-二脱氢植物鞘氨醇(2R)-2-羟基脂肪酰胺,其脂肪酸链主要由十六,二十二,二十三,二十四和二十五烷酸组成,其中2-羟基十六碳酸组成的神经酰胺(2S,3S,4R,8E)-2-[(2R)-2-羟基棕榈酰胺]-8-十八碳烯-1,3,4-三醇为一新化合物。高锰酸钾氧化法被应用于判断单不饱和长链中双键的位置。
A mixture of five ceramides was isolated from the roots ofSerratula chinensis （Compositae）. The structures of these compounds were elucidated as （2S, 3S, 4R, 8E）-2-amino-8-octadecene-1, 3, 4-triol with five 2-hydroxy fatty acids of varying chain lengths （C16, C22-25） linked to the amino group （1a-1e, respectively）. Ceramide la was a new compound. The structures were established by spectroscopic and chemical means. The KMnO4 oxidation method was applied to locate the double bond position in monounsaturated long chain bases.
