摘要/Abstract

摘要：

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。

Abstract:

The volatile oil composition of seeds (SPF) and leaves (LPF) of Perilla frutescens (L.) Britt. was investigated by two-dimensional gas chromatography-mass spectrometry (GC-MS). The overlapped spectral data of SPF and LPF volatile oils were resolved by chemometric method into a pure chromatogram and a mass spectrum of each compound, which was qualified by mass spectral library search. In total, 85 volatile chemical components from SPF and 74 from LPF were identified, which accounted for 97.92% and 98.56% of total volatile oil, respectively. Forty-five volatile components were observed in both SPF and LPF, occupying 52.94% and 60.81% of total numbers of volatile oil components identified in SPF and LPF, occupying 84.30% and 66.38% of total contents, respectively. The dominant common volatile chemical components in SPF and LPF were D-Limonene, bicyclo[7.2.0]undec-4-ene,4,11,11-trimethyl-8-methylene-Bicyclo[3.1.1]hept-2-ene, 2,6-dimethyl-6-(4-methyl- 3-pentenyl)-, caryophyllene oxide, 1-pentanone, 1-(2-furanyl)- and tricyclo[3.1.0.0(2,4)]hexane,3,6-diethyl-3,6-dimethyl-.

Key words: seeds of Perilla frutescens (SPF), leaves of Perilla frutescens (LPF), volatile oil, gas chromatography-mass spectrometry (GC-MS), chemometric resolution method (CRM)
