摘要
采用固相微萃取法萃取粉碎草果香气成分,然后用GC-MS进行成分分析,并与水蒸气蒸馏萃取法获得的精油成分进行比较.萃取柱为CAR/PDMS时共检测出30个成分,解析鉴定出占总挥发性成分的97.635%的27种物质.水蒸气蒸馏萃取法以1.87%(w/w)的产率获得精油,共检测出38个成分,解析出的成分占精油质量的98.393%的32种成分,主要成分是1,8-桉树脑(40.891%)(质量分数,以下同),α-水芹烯(9.769%),2-异丙基苯甲醛(6.988%),(E)-柠檬醛(4.949%),α-蒎烯(4.36%).
Aromatic components of Amomum tasoko powder were extracted and analyzed by head space-solid phase microextraction and combined with GC-MS,and compared with the components of the essential oil.30 Components were detected and 27 compounds(97.635% of total) were identified when the CAR/PDMS column was used.The essential oil was obtained by the method of steam distillation extraction in 1.85% yield(w/w).A total of 38 constituents were detected,in which 32 compounds that account for 98.393% were identified.The main constituents were 1,8-cineole(40.891%)(mass fraction),α-phellandrene(9.769%),4-propylbenzaldehyde(6.988%),(E)-citral(4.949%) and α-pinene(4.36%).
