摘要
采用超临界二氧化碳萃取法(SFE-CO2)提取芹菜籽挥发油;用气相色谱-质谱联用技术(GC-MS)对芹菜籽挥发油化学成分进行分离鉴定,共分离出36种化学成分,鉴定的27种化合物占挥发油总含量的99.72%,含量最高的物质为柠檬烯(33.08%),其次分别为N,N’-1,2-二苯基乙酰胺(23.04%),γ-榄香烯(14.96%),2-氯-1-(3,4-二甲基苯基)-2-甲基-1-丙酮(6.01%),N,N’-二乙酰基-1,4-苯二胺(5.73%),石竹烯(3.51%)等;利用紫外分光光度计计算芹菜籽挥发油对亚硝酸钠的清除率,实验结果显示芹菜籽挥发油可以明显的清除亚硝酸钠,当挥发油用量为40μL时,清除率最大为89.80%。
Volatile oils from celery seeds were extracted by SFE-CO2 technique. And its chemical constituents were identified by GC-MS. 36 constituents were separated from volatile of celery seeds. And 27 compounds were identified which accounts for 99.72% ,the content of limonene in the volatile oil of celery seed was the highest （ 33.08 % ）, the other chemical constituents were acetamide, N, N＇ - 1,2- phenyleneb （23.04%）, y- elemene （ 14.96% ）, 1 - propanone, 2-chloro- 1 - （2,5-dimethylphenyl ） -2-methyl- （6.01% ）, N, N＇ -diacetyl- 1,4- phenylenediamine （5.73%）, caryophyllene （3.51% ）, The removal rate of essential oil of celery seed on sodium nitrite was calculated by ultraviolet spectrophotometer. Results showed that the volatile oils of celery seeds were able to scavenge sodium nitrite efficiently. Maximum removal rate was 89.80% ,when the amount of volatile oils was 40μL.
