大理产凤尾茶挥发油成分的研究

Study on Chemical Composition of the Essential Oil from Elsholtzia bodinieri Vaniot

[目的]全面了解凤尾茶的挥发油成分,更好地开发利用这一重要药用植物资源。[方法]以采自云南大理的凤尾茶为试材,用水蒸汽蒸馏法提取凤尾茶中的挥发油,采用气相色谱-质谱联用法对凤尾茶挥发性成分进行分析鉴定,用面积归一化法确定各化合物的相对含量。[结果]GC-MS分析表明,从凤尾茶挥发油中鉴定出了41个化学成分,占挥发油峰面积的62.368%。化合物类型包括单萜(43.138%)、倍半萜(5.553%)、芳香族(11.447%)和脂肪族(1.781%)。主要成分为台薷酮(38.945%),其次为茴香苯甲醇(8.994%)、臭樟脑(2.324%)和β-波旁老鹳草烯(2.313%)等,其中萜类化合物的含量最高,占挥发油总量的48.691%。[结论]该研究为凤尾茶资源在药用和香料等方面的进一步综合利用提供了参考依据。

[Objective] The study was to fully know the chemical composition from the essential oil from Elsholtzia bodinieri Vaniot so as to develop and utilize this important medicinal plant resources. [Method] With E. bodinieri selected from Dali of Yunnan Province as the test mate- rial, its essential oil was extracted by steam distillation method, its composition of the essential oil was analyzed and identified by GC-MS method and the relative content of each compound was confirmed by the area normalization method. [Result] GC-MS analysis showed that 41 chemical compositions were identified from the essential oil of E. bodinieri, which amounted for 62.368% of the total peak area of essential oil. The compound types included monoterpenes （43.138% ）, sesquiterpenoids （5.553%）, aromatics （11.447%） and aliphatics （1. 781%） and the main constituents were Dehydroelshohzia ketone （38.945%）, followed by 4-（1-methylethyl）-Benzenemethanol（8.994%）, Naphtha-lene（2.324%） and β-bourbonene （2.313%）, in which, the content of terpenoid was highest, amounting for 48.691% of total essential oil.[Conclusion] This study provided the reference basis for further comprehensive utilization of E.bodinieri resources on medicinal purposes and perfume etc.
