正交试验法优选蝴蝶果茎挥发油提取工艺

Optimization of Extracting Technology for Volatile Oil from Cleidiocarpon cavaleriei(Lévl.) Airy Shaw Stem by Orthogonal Test

[目的]利用正交设计法提取蝴蝶果茎挥发油。[方法]采用正交试验设计L9(34),以得油率为指标,确定最佳提取工艺条件。[结果]结果表明,蝴蝶果茎浸泡0 h,加水量为15倍,提取4 h时得油率最高。[结论]该工艺为蝴蝶果茎挥发油的最佳提取工艺。

The research aimed to optimize the extraction technology for volatile oil from Cleidiocarpon cavaleriel （Levl.） Airy Shaw stem. [ Method ] Using the orthogonal design L9 （3^4 ）, by means of the gained-rate, the best condition of gained-rate process was con- firmed. [ Result ] The results showed that the extraction rate was the highest under the condition of soaking the Cleidiocarpon cavaleriei （Levl.） Airy Shaw stem 0 h, 15 times with water, extraction time 4 h. [ Conclusion ] This process was the best process to extract volatile oil from Cleidiocarpon cavaleriei （Ievl.） Airy Shaw stem.
