固相微萃取-气质联用法测定紫苏子挥发性成分

Determination of Volatile Components of Perilla Seeds using the SPME-GC-MS Method

采用固相微萃取法(SPME)萃取紫苏子的挥发性物质,经气相色谱-质谱联用仪(GC-MS)检测,结果表明,紫苏子的挥发性成分主要由石竹烯、紫苏醛、a-石竹烯、柠檬烯、临氨基苯甲酸沉香酯、4-乙烯基-4-甲基-3-异丙烯基-1-异丙基-环己烯、(E,E)-1-甲基-5-亚甲基-8-异丙基-1,6-环癸二烯、2,6-二甲基-6-(4-甲基-3-戊基)双环[3.1.1]己-2-烯、1,4-二乙基-1,4-二甲基-2,5-环己二烯等组成,其中石竹烯相对含量最高(41.2%),紫苏醛次之(12.38%)。

Volatile compounds of Perilla seeds were determined by using the HS-SPME-GC-MS method. Results showed that the main compounds are Perilla aldehyde, 1,6-Octadien-3-ol, caryophyllene, 3,7-dimethyl-2-aminobenzoate, limonene, alpha-caryophyllene, 1,4-diethyl-1,4-dimethyl-2,5-Cyclohexadi- ene, 2,6-dimethyl-6- (4-methyl-3-pentenyl)-bicyclo [3.1.1]hept-2-ene, 3R-trans-4-ethenyl-4-methyl-3- (1-methylethenyl)-1-(1-methylethyl)-cyclohexene, of which caryophyllene is the highest in content (41.2 %), followed by Perilla aldehyde (12.38 %).
