一种快速提取丁香油的新方法

The New Method for Quick Steam Distillation of Clove Oil

用回流提取法、水蒸汽蒸馏法、快速提取法对丁香花蕾中丁香油提取进行了比较,并确定丁香花蕾中丁香油的最佳提取方法和条件。结果表明,快速提取法比回流提取法、水蒸汽蒸馏法提取效率高,快速简便。快速提取法提取丁香油的最佳条件为:原料与水比为1∶10,提取回流时间为90m in,产品收率达12.96%,且含丁香酚95.38%。

Three methods were compared of preparing clove oil. in Lilac,the methods are ethanol refluxing extraction, normal steam distillation and quick distillation, and to ascertain out a better method and optimum operating conditions. The results showed that quick distillation are superior to ethanol refluxing extraction and normal steam distillation, and the method was fast and simple. The best conditions of the method were. the ratio of clove powder to water-1 ： 10, and time of distillation. 90 min,the yield of the oil 12. 96% with the content of eugenol in clove oil 95. 38%.
