摘要
[目的]优化姜中姜油酮的超临界CO2萃取条件,为姜的进一步开发利用奠定基础。[方法]通过单因素试验优化姜油酮的萃取条件,采用SPSS的一般线性模型对试验数据进行单变量多因素方差分析。[结果]最佳萃取条件为:萃取压力25 MPa,萃取温度45℃,萃取时间150 min。各因素对姜油酮的萃取率影响大小顺序为萃取压力>萃取时间>萃取温度。[结论]该研究得到姜油酮萃取的最佳条件,为姜的进一步开发利用奠定了基础。
[Objective] To optimize the supercritical carbon dioxide fluid conditions for extracting the zingerone in ginger oleoresin from Zingiber officinale Roscoe,so as to provide basis for the further development and application of Zingiber officinale Roscoe.[Method] The extraction conditions were optimized by single factor test,and the data were subjected to analysis of variance by general liner model（GLM）in software SPSS.[Result] The optimum extracting conditions were as follows：pressure of 25 MPa,temperature of 45 ℃ and extraction duration of 150 min.The influencing order of each factor on extraction rate of zingerone was determined to be：pressuretimetemperature.[Conclusion] The optimal extraction supercritical carbon dioxide fluid conditions for extracting zingerone was obtained in this study,which provided basis for the further development and application of Zingiber officinale Roscoe.
