| 摘 要： | 采用索氏萃取法萃取新鲜芫荽茎叶芳香成分,获得芳香精油,得油率为0．252%。利用GC-MS对精油进行了分析,检测出60个成分,解析出41个成分,占94．200%。其中,酯类化合物含量最高,占总油量57．755%。其次为烷烃类化合物,占总油量的11．300%。醛类化合物16．168%,芳香族化合物8．077%。研究了精油对亚硝酸钠消除效果,当精油用量为0．8ml时,清除率为最大69．7%。

| Abstract: | The essential oils were extracted from the fresh aerial parts of coriander(Coriandrum sativwn L.)by Soxhlet's extraction method to reach 0.252% yield.The components of the essential oil were analyzed by GC-MS,and a total of 60 constituents were assayed with 41 compounds identified accounting for 94.200% of total.The esters are the most abundant accounting for 57.755%,with hydrocarbons 11.300%.Aldehydes and aromatic comkpounds account for 16.168% and 8.077%, respectively.The essential oils were studied for scavenging effects of sodium nitrite.The maximum scavenging rate is 69.7% when used essential oil 0.8ml. |
