八角茴香油的化学成分及其抗氧化性研究

Study on chemical components and antioxidation of oil of Illicium Verum Hook.f.

以广西三种八角茴香(大红八角、干枝八角、角花八角)为原料研究其挥发油的化学成分及抗氧化性能。以石油醚为溶剂、索氏法提取挥发油,通过GC-MS分析手段对挥发油的大部分成分进行了分析,并用峰面积归一化法确定各组分的相对含量;采用Fenton法及邻苯三酚法探讨了三种挥发油的抗氧化性能。结果表明:干枝八角、角花八角挥发油中茴香醛(对甲氧基苯甲醛)的含量分别高达21.25%,10.46%;三种挥发油都具有一定的抗氧化性,其中干枝八角挥发油对.OH及O.清除效果最好。

The volatile oil was extracted from three kinds of Illicium verum Hook.f.（scarlet Star Anise,natural drying Star Anise and Hua Kok Star Anise）which grow in Guangxi by Soxhelt method with petroleum ether.Chemical components and antioxidant capacity of the volatile oil were studied.Most of chemical components were analyzed by the method of GC-MS,the relative contents of these compounds were calculated using square peaks to normalization;Antioxidant capacity of three kinds of volatile oil were researched with the method of Fenton and pyrogallol.the result shows： in the volatile oil of natural drying Star Anise and Hua Kok Star Anise,the content of Anisaldehyde（p-methoxyl benzaldehyde）attain to 21.25% and 10.46% respectively,all of them have some degree of antioxidant capacity,the volatile oil of natural drying Star Anise has best clearance capacity to·OH and O· among them.
