采用气相色谱-质谱(GC-MS)法分离测定紫苏叶与紫苏子挥发油成分,利用化学计量学解析法对重叠的色谱峰进行解析,得到各组分的纯色谱曲线和质谱,通过质谱库对解析的纯组分进行定性,紫苏叶挥发油的定性组分74个,占总含量的98.56%;紫苏子挥发油的定性组分85个,占总含量的97.92%。结果表明,紫苏叶与紫苏子挥发油共有组分数45个,分别占鉴定组分数的60.81%、52.94%;占鉴定组分量的66.38%、84.30%。相对含量较高的组分是柠檬烯、4,11,11-三甲基-8-亚甲基二环十一碳烯、2,6-二甲基-6-(4-甲基-3-戊烯基)双环庚-2-烯、石竹烯氧化物、1-(2-呋喃)-戊酮、3,6-二乙基-3,6-二甲基-三环己烷。
The components of the essential oil of Perilla frutescens and Perilla frutescens were separated and determined by gas chromatography-mass spectrometry (GC-MS). The chromatographic peaks were analyzed by stoichiometry. The pure chromatograms and mass spectra of each component were obtained. The library was used to characterize the pure constituents of the analysis. There were 74 qualitative components of the volatile oil of Perilla frutescens, accounting for 98.56% of the total content. The qualitative components of the essential oil were 85, accounting for 97.92% of the total content. The results showed that there were 45 common components of perilla leaves and perilla oil, accounting for 60.81% and 52.94% of the identified components respectively, accounting for 66.38% and 84.30% of the identified components respectively. Relatively high levels of the components are limonene, 4,11,11-trimethyl-8-methylenebicycloundecene, 2,6-dimethyl-6- (4-methyl- Pentenyl) bicyclohept-2-ene, caryophyllene oxide, 1- (2-furan) -pentanone, 3,6-diethyl-3,6-dimethyl-tricyclohexane.
