摘　　要：以植物倍花为原料制备倍花挥发油和倍花提取液,用气相色谱-质谱联用技术分析了挥发油的化学成分和提取液的脂肪酸组成与含量。实验结果表明,挥发油中共检出五十个组分,主要成分是乙基异丙醚、己酸、N,N-二甲基苯胺、月桂酸、肉豆蔻酸、棕榈酸、7(Z),10(Z),13(Z)-十六碳三烯酮,其相对含量分别为17.94%、4.48%、3.43%、3.72%、14.89%、8.88%、23.8%。倍花提取液经甲酯化后共检出十八种物质,其中有十种脂肪酸,不饱和脂肪酸与饱和脂肪酸总含量分别为19.2%和51.7%;不饱和脂肪酸中亚麻酸含量达16.13%,饱和脂肪酸主要是肉豆蔻酸和棕榈酸,含量分别为26.88%和17.03%。Volatile oils and extracts were prepared from beihua.Compounds in volatile oil and fatty acids in extrats were analyzed by gas chromatography-mass spectrometry.The results showed that fifty compounds were detected from volatile oil with 17.94%of ethyl isopropyl ether,4.4% of hexanoic acid,3.43% of N,N-dimethylaniline,3.72% of dodecanoic acid,14.89% of tetradecanoic acid,8.88% of palmitic acid and 23.8% of cis,cis,cis-7,10,13-hexadecatrienal being the main components.Eighteen compounds were detected from extracts of methyl-esterification,and ten of them are fatty acids.The content of unsaturated fatty acids is 19.2% with linolenic acid being 16.13%,and that of saturated fatty acids is 51.7% with tetradecanoic acid and palmitic acid of 26.88%and 17.03%,respectively.
