【摘 要】 目的:明确留兰香药材主要有效成分香芹酮的主要分布部位。方法:先采用薄层色谱法初步观察香芹酮在留兰香根茎叶中的含量差别,再采用气相色谱法定量测定留兰香药材不同部位中香芹酮的具体含量。结果:留兰香药材叶中香芹酮的含量最高,其次是茎,最后是根。结论:留兰香药材中香芹酮的主要分布部位为叶,根和茎中的含量很低。

Abstract:Objective To identify the main distribution sites of varvone-a main effective composition in spearmint and to provide reliable basis for improve spearmint utilization efficiency. Methods The difference of carvone content in roots、stems and leaves of spearmint was preliminarily observed by TLC, and then the specific amount of carvone in different parts of spearmint was quantitatively determined by GC.Result The leaves of spearmint had the most content of carvone, followed by the stems and finally the roots.Conclusion The main distribution of carvone in spearmint is the leaves, and the content of carvone in the stems and the roots was very low.

留蘭香(Mentha spicata L.)为唇形科薄荷属(Mentha Linn)植物,又名狗肉香,在我国贵州、云南、四川、新疆等地均有栽培,其味辛、甘,性微温,具有疏风解表、理气止痛、之功效。现代药理研究表明:留兰香具有抗菌、抗炎、抗病毒及抗氧化活性[1-4],常用于治疗感冒发热、咳嗽、头痛、咽痛、跌打瘀痛、胃肠胀气、乌疔、鸡窝寒、全身麻木和小儿疮疖。留兰香味清新、凉爽、香甜,其嫩叶常做调味香料食用,其挥发油广泛应用于牙膏、口香糖、糖果、香皂等物品的加香[5]。根据文献报道香芹酮为留兰香挥发油的主要有效成分[6],但其在全草中的含量分布情况尚不明确,为提高留兰香资源的利用效率,本实验采用气相色谱法(GC)及薄层色谱法对其根、茎、叶中的香芹酮含量差异进行比较。
