摘要： 采用超临界CO2萃取技术提取香蕉花蕾鲜样、干样的精油,并运用GC-MS技术,对其化学成分进行了鉴定,并用峰面积归一化法确定各成分的相对百分含量。结果表明：从香蕉花蕾鲜样、干样精油中分别鉴定出13和14种化合物,其中 9种为共有成分,但各成分的含量有差异。香蕉花蕾鲜样精油的主要成分为9,19-Cycloergost-24(28)-en-3-ol,4,14 -dimethyl-, acetate,(3á, 4à,5à)-(49.04%)、甲酸1-二十一酯(10.84%)、四十三烷(10.39%)、(Z)-9-十八烯酸酰胺(9.12%)、2-十八烷氧基乙醇(6.83%)。香蕉花蕾干样精油的主要成分为9,19-Cycloergost -24(28) -en-3-ol,4,14-dimethyl-, acetate,(3á,4à,5à)-(34.18%)、二十七烷醇(17.89%)、甲酸1-二十一酯(17.22%)、2-十八烷氧基乙醇(10.16%)、(Z)-9-十八烯酸酰胺(5.67%)。

Abstract: The essential oil of fresh and dried banana bud was extracted by supercritical CO2 fluid extraction technology, and their compositions and relative contents were quantitatively determined by GC-MS with peak areas normalization method. The result indicated that 13 and 14 compounds were identified from fresh and dried banana bud respectively, and 9 compounds were presented in both fresh and dried samples but the percentage contents were obvious difference. The major compositions of fresh banana bud were 9,19-Cycloergost-24(28)-en-3-ol,4,14 –dimethyl-,acetate,-(3á,4à,5à)- (49.04%), 1-Heneicosyl formate (10.84%), Tritetracontane (10.39%), 9-Octadecenamide,(Z)- (9.12%), Ethanol,2-(octadecyloxy)- (6.83%). The major compositions of dried banana bud were 9,19-Cycloergost-24(28) -en-3-ol,4,14 -dimethyl-,acetate,(3á,4à,5à)- (34.18%), 1-Heptacosanol (17.89%), 1-Heneicosyl formate (17.22%), Ethanol,2-(octadecyloxy)- (10.16%), 9-Octadecenamide,(Z)- (5.67%).
