海南产山柰挥发油化学成分分析

目的:分析海南产山柰挥发油的化学成分。方法:采用水蒸气蒸馏法提取山柰挥发油,用气相色谱-质谱联用技术(GC-MS)进行测定,并用色谱峰面积归一法确定各化学成分的相对含量。结果:从海南产山柰挥发油中分离出21个色谱峰,鉴定出19种化合物。挥发油主要成分和相对含量分别为:对-甲氧基肉桂酸乙酯(49.118%)、肉桂酸乙酯(19.323%)、十五烷(15.018%)、δ-蒈烯(5.270%)。结论:本方法为山柰挥发油生理活性和作用机制的进一步研究提供了资料,同时也为其产品的开发应用提供了科学依据。

Determination of Chemical Constituents of Galanga Resurrectionlily Rhizome from Hainan Province by GC - MS

OBJECTIVE ： To analyze the chemical constituents of Galanga Resurrectionlily Rhizome from Hainan province. METHODS： Galanga Resurreetionlily Rhizome volatile oil was extracted by wet distillation method and determined by GC- MS, and the relative content of different constituents was determined by chromatographic peak area normalization method. RESULTS： For Galanga resurrectionlily rhizome volatile oil, 21 chromatographic peaks were separated and 19 chemical constituents were detected. The chief constituents of the volatile oil were Ethyl-p- methoxycinnamate（49.118% ）, ethyl cinnamate （19.323%）, pentadecane （15. 018% ） and δ- careen （5. 270% ）. CONCLUSION： This method provided not only data for the further study of the physiological activity and action mechanism of Galanga Resurrectionlily Rhizome volatile oil but also scientific basis for the development and application of Galanga Resurrectionlily Rhizome volatile oil.
