应用气相色谱和薄层鉴别的方法,对山柰Kaempferia galanga L.和苦山柰Kaempferia marginata Carey精油的化学成分进行了比较研究,共鉴定了反—对甲氧基桂皮酸乙酯、桂皮酸乙酯、龙脑等30个化学成分。研究表明,山柰和苦山柰精油的化学成分基本相同,但是其中某些成分如反—对甲氧基桂皮酸乙酯、1,8—桉油素、十五烷等,在含量上相差较大,因此,二者是不能混用的。 Gas chromatography and thin layer identification methods were used to compare the chemical constituents of Kaempferia galanga L. and Kaempferia marginata Carey essential oils. A total of four anti-p-methoxy cinnamic acid esters and cinnamic acid B were identified. Ester, borneol and other 30 chemical components. Studies have shown that the chemical composition of the essential oils of Hawthorn and Bitter Hawthorn are basically the same, but some of these components, such as ethyl anti-p-methoxycinnamate, 1,8-aramid, pentadecane, etc., differ in their contents. Larger, therefore, the two can not be mixed.
