杜衡挥发油的超声波协同微波辅助提取及其GC/MS分析
Ultrasonic-microwave synergistic extraction and GC/MS analysis of volatile oil from Asarum forbesii Maxim
摘要
Abstract
The influences of solvent to material ratio, microwave power and extraction time on the extraction yield of volatile oil from Asarom forbesii Maxim with the ultrasonic -microwave synergistic extraction (UMSE) technique were studied.Box - Behnken experimental design was based on the single factor experiments.One mathematical model established and analyzed by response surface methodology (RSM) was adequate to describe the relationships between the studied factors and the response of volatile oil extraction yield.Based on the canonical analysis, the optimum extraction conditions were obtained as follows: solvent to material ratio 10mL/g, microwave power 234W and extraction time 131s.Under the optimized extraction conditions, the extraction yield is 8.29％, which is close to the estimated value 8.32％ attained by using regression model.This model can well predict the experiment results.Then the chemical components of the volatile oil were examined by GC - MS.Finally 30 kinds of compounds were separated, 21 kinds of compounds were identified, and the relative contents of these components were determined by peak area normalization method.关键词
