超临界二氧化碳萃取法提取石岩枫挥发油成分分析
|
摘要
目的:比较超临界二氧化碳萃取法提取石岩枫茎与叶挥发油成分。方法:使用超临界二氧化碳萃取法(SFE-CO_2)分别提取石岩枫茎与叶的挥发油,并通过气相色谱-质谱联用(GC-MS)分析挥发油成分。结果:石岩枫茎分离出20个化合物,鉴定出15个化合物,占总流出组分的77.37%,石岩枫叶分离出35个化合物,鉴定出27个化合物,占总流出组分的79.68%,叶比茎鉴定出的化合物的种类多出12种,共有成分为9个。结论:两种部位分离的挥发油成分存在明显差异。
Objective:To compare the difference of volatile oil composition between Mallotus repandus(Willd.)Muell.-Arg stems and leaves by SFE-CO_2. Methods:The volatile oil of stem and leaf was extracted by(SFE-CO_2)respectively,and the difference of volatile oil composition was analyzed by(GC-MS). Conclusion:The stems isolated 20 compounds,identified 15 compounds,accounted for77.37% of the total outflow components,leaves isolated 35 compounds,identified 27 compounds,accounting for 79.68% of the total outflow components,12 kinds of compounds more in leaves than stems,and the same composition is 9. Results:There were obvious differences in the components of volatile oil separated from two different parts.
