肉桂降糖活性成分提取方法的研究

Study on cinnamon hypoglycemic active ingredient extraction method

用乙醇回流提取法、超声波提取法、新装置提取法提取肉桂降糖活性成分。结果表明,新装置提取法比回流提取法、超声波提取法提取效率高,且快速简便。新装置提取法提取肉桂降糖活性成分的最佳条件为:多功能提取器装置,提取溶剂为95%乙醇,提取时间2 h,产品粗提率达21.0%。

Three methods were compared of preparing cinnamon hypoglycemic active ingredients：the etha-nol refluxing extraction,ultrasonic extraction and the new device extraction. The results showed that the new device extraction was superior to ethanol refluxing extraction and ultrasonic extraction,and the meth-od was fast and simple. The best conditions of the method were：multi-extractor device,solvent of 95%ethanol,and the time of extraction was 2 h,the coarse product rate was 21. 0% .
