同时蒸馏萃取法提取霞草挥发油的GC-MS分析

GC-MS Analysis of the Volatile Oil from Oldham gypsophila by Simultaneous Distillation Extraction

[目的]采用GC-MS分析法测定同时蒸馏萃取法提取的霞草挥发油中化学成分含量。[方法]采用同时蒸馏萃取法提取霞草中的挥发油,然后运用气相色谱-质谱联用技术分析萃取物,利用峰面积归一化法确定挥发性组分的相对含量。[结果]从霞草的挥发油中共鉴定出61种主要挥发性成分,其中乙基异丙基醚(12.446 5%)、3-甲基-2-环氧基甲醇(11.878 5%)和2-甲基萘(9.358 6%)是构成霞草挥发性物质的主要成分。[结论]该研究为霞草的进一步开发和利用提供了科学依据。

[ Objective ] Chemical composition content in volatile oil of Oldham gypsophila was measured by GC-MS analysis, and simultaneous distillation extraction was also adopted. [ Method ] Volatile oil was extracted from 0. gypsophila by simultaneous distillation extraction. Then, extracts were analyzed by GC-MS. Relative contents of the volatile components were determined by peak area normalization. [ Resuh] A total of 61 volatile components were identified. Among them,2-ethoxy-propane （ 12. 446 5 % ） , （3-methyl-oxiran-2-yl） -methanol （ 11. 878 5 % ） and 2- methyl- naphthalene （9. 358 6% ） were the main components constituting volatile components. [ Conclusion I This research provided scientific basis for the further development and utilization of 0. gypsophila.
