银环蛇蛇蜕的化学成分研究Ⅱ.脂肪酸和氨基酸组分

Study on Chemical Components of Snake Slough of Bungarus Multicinctus Multicinctus Ⅱ. Components of Fatty Acids and Amino Acids

用色谱 -质谱 (GC -MS)联用技术分析了银环蛇蛇蜕的脂肪酸成分 ,鉴定出36种脂肪酸 (饱和酸28种、不饱和酸8种 ) ,在蛇蜕中发现16种饱和二元酸 ,并发现了自然界中少见的奇数碳脂肪酸14种及支链酸2种。用氨基酸自动分析仪测定了蛇蜕水提取液中的13种游离氨基酸 ,酸性水解液中17种氨基酸 。

The components of fatty acids in snake slough of Bungarus multicinctus multicinctus were ana_lyzed by GC-MS. Thirty _ six fatty acids including twenty _ eight saturated acids and eight unsaturated acids were identified. There are fourteen fatty acids with odd carbon atoms and two branched chain fatty acids in the snake slough. These fatty acids were seldom found in nature. Thirteen free amino acids in water extracts and seventeen amino acids in acid hydrolysis product from the snake slough were determined by amino acid autoanalyzer. Relative abundant taurine was also found in the snake slough.
