摘要
目的:分析测定薯莨Dioscorea Cirrhosa Lour.块茎中的脂肪酸和挥发油的含量及种类。方法:采用气相色谱-质谱联用仪进行测定。结果:从脂肪酸组份中分离出50个峰,鉴定出12种脂肪酸,其中主要成分有9,12-十八碳二烯酸(亚油酸,21.59%)、十六酸(棕榈酸,16.22%)等;挥发油组分中分离出32个峰,鉴定出32种化合物,其中间甲基苯酚、苯酚、2-甲基苯酚含量较高,分别占挥发油总量的26.92%,18.95%,12.12%。结论:对薯莨块茎中脂肪酸、挥发性组分进行了分析测定,为进一步综合开发利用薯莨提供了一定的理论依据。
Objective：The volatile oil and fatty acid of the Dioscorea cirrhosa.were analyzed.Method：In this study,the capillary GC-MS was used.Result：Fifty peaks were separated,12 compounds were identified from the fatty acids,the tuber of D.cirrhosa contained abundant octadecadienoic acid and hexadecanoic acid,they were 21.59% and 16.22%of total fatty acids respectively.And 32 peaks were separated and 32 compounds were identified from the volatile oil,m-cresol（26.92%）,phenyl hydroxide（18.95%）,o-cresylic acid（12.12%） were the dominant constituents.Conclusion：The results provide the scientific basis for comprehensive development and utilization of D.Cirrhosa.
