目的:阐明羚羊角中脂肪酸类成分。方法:溶剂法提取脂类成分,经甲酯化,采用气相色谱-质谱-计算机联用技术分离鉴定,归一化法计算相对百分含量。结果:从羚羊角中鉴定出9种脂肪酸类成分,占总脂的85.14%,其中不饱和脂肪酸3种,占17.92%。结论:羚羊角中主要脂肪酸类成分为棕榈酸、硬脂酸、油酸,占80.31%。 Objective: To elucidate the fatty acids in the antelope horn. Methods: The lipids were extracted by solvent method, separated by methyl esterification and identified by gas chromatography - mass spectrometry - computer combined technique. The relative percentage was calculated by normalization method. Results: Nine kinds of fatty acid components were identified from the antelope horn, accounting for 85.14% of the total lipids, of which three species were unsaturated fatty acids accounting for 17.92%. Conclusion: The main fatty acids in the antelope horn are palmitic acid, stearic acid and oleic acid accounting for 80.31%.
