从垂花叶中分离得到9个糖苷和1个单酰基单半乳糖基甘油。糖苷的结构被表征为植物鞘氨醇的1-O-β-D-葡萄糖苷，其包含一个共同的长链碱基，（2S，3S，4 R，8 Z）-2-氨基-8（Z）-十八烯-1，3，4-三醇，其中9个不同链长（C-16，C-18，C20-26）的2-羟基脂肪酸连接到氨基。糖基甘油酯的特征为（2S）-1-O-亚麻烯酰基-3-O-β-D-吡喃半乳糖基甘油。根据光谱数据和化学反应确定了其结构。
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, C20-26) linked to the amino group. The glycosylglyceride was characterized as (2S)-1-O-linotenoyl-3-O-beta-D-galactopyranosylglycerol. The structures were established on the basis of the spectroscopic data and chemical reactions.
