摘　　要：先用微波对肉桂皮进行预处理 ,改变肉桂皮的组织结构 ,然后用热水提取肉桂皮中的肉桂醛 ,并与传统的提取方法进行比较。结果得到微波预处理提取法的最佳工艺条件是用重量 1.2倍的 75 %乙醇水溶液湿润肉桂皮 ,然后用 75 0 W功率微波处理 ,处理时间为每增加 5 g桂皮 ,时间增加 10 s,最后加入 5 0倍热水提取 1h。微波预处理提取法的提取时间比传统方法缩短一半 ,肉桂醛的提取率提高 2 0 %。The method of extracting cinnamldehyde from Cinnamomum cassia bark,which was disorganized by means of microwave pretreatment,is compared with the traditional one.The optimum technical conditions are as follows: wetting Cinnamomum cassia bark by ethanol liquor of concentraction 75%,every 5 grams of Cinnamomum cassia increase by 10 seconds under 750 watts,then draw in hot water for an hour.The results showed that the extracting time has been shortened by half than the traditional one,while it's extracting ratio has been improved by 20%.
