A mixture of nine cerebrosides and a monoacylmonogalactosylglycerol were separated from the leaves of Clinacanthus nutans. The structures of the cerebrosides were characterized as 1-O-beta-D-glucosides of phytosphingosines, which comprised a common long-chain base, (2S,3S,4R,8Z)-2-amino-8(Z)-octadecene-1,3,4-triol with nine 2-hydroxy fatty acids of varying chain lengths (C(16), C(18), C(20-26)) linked to the amino group. The glycosylglyceride was characterized as (2S)-1-O-linolenoyl-3-O-beta-D-galactopyranosylglycerol. The structures were established on the basis of the spectroscopic data and chemical reactions.
从鳄嘴花叶子中分离出了九种脑苷脂和一种单酰基单半乳糖基甘油的混合物。脑苷脂的结构被鉴定为植物鞘氨醇的1-O-β-D-葡萄糖苷,其包含一个常见的长链碱基,即(2S,3S,4R,8Z)-2-氨基-8(Z)-十八碳烯-1,3,4-三醇,与九个不同链长(C(16)、C(18)、C(20 - 26))的2-羟基脂肪酸连接到氨基上。糖基甘油酯被鉴定为(2S)-1-O-亚麻酰基-3-O-β-D-吡喃半乳糖基甘油。这些结构是根据光谱数据和化学反应确定的。
