南海Spirasterella中脂肪酸酯组分的鉴定

用色谱—质谱联用技术分析了中国南海海绵Spirasterella aurivilli Lindgren中脂肪酸酯组分。鉴定了29种脂肪酸酯,其中20种饱和脂肪酸乙酯,8种不饱和脂肪酸乙酯及1种饱和脂肪酸甲酯。并发现该海绵中含有自然界少见的10种奇数碳脂肪酸乙酯。

IDENTIFICATION OF THE COMPONENTS OF ESTERS OF FATTY ACIDS FROM SPONGE SPIRASTERELLA AURIVILLI LINDGREN

A colorless oil has been isolated from South China Sea Sponge Spirasterella aurivilli Lindgren by chromatographies on silica gel. The components of the oil have been analysed by means of GC-MS. 29 constituents have been identified from peaks of RIC, including 20 saturated ethyl esters of fatty acids, 8 unsaturated ethyl esters of fatty acids and 1 saturated methyl ester of fatty acid. There are 10 kinds of odd carben esters of fatty acids which are seldom found in the natural products identified. It is first reported about the chemical components of the Sponge.
