摘要
对杜仲皮和杜仲叶采用不同处理方法进行干燥,并考察这些处理方法对杜仲皮及叶中的几种活性成分含量的影响。经过微波处理后,叶中绿原酸、总黄酮和桃叶珊瑚苷的质量分数分别为2.129%、7.005%和4.420%,是晒干处理的5.14倍、1.52倍和17.06倍;皮中京尼平苷酸和桃叶珊瑚苷的质量分数分别为5.393%和4.242%,分别是晒干处理的1.09倍和1.78倍。结果表明微波杀青后50℃烘干处理杜仲皮及叶能够有效的减少活性成分的损失,是一种比较好的处理方法。
Barks and leaves of Eucommia ulmoides Oliv. were processed by different methods. Effect of different processing meth- ods on the content of several active ingredients was investigated in this paper. The contents of chlorogenic acid, total flavonoid and aucubin in leaves after treatment by microwave deactivation were 2. 129 % , 7. 005 % and 4.420 % respectively. They were 5.14, 1.52 and 17.06 limes respectively as much as those by sun drying. The contents of geniposidic acid and aucubin in barks were 5. 393 % and 4.242 % respectively which were 1.09 and 1.78 times respectively as much as those by sun drying. Results showed that the method,i, e. 50 ℃ stoving after processed by microwave deactivation, could effectively reduce the loss of active ingredients.
