草果香气成分研究

Comparison of aromatic components and essential oil from Amomum tasoko

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%）.
