不同干燥方法对“武当二号金银花”总黄酮含量的影响

Effects of Different Drying Methods on Total Flavonoids Content of "Wudang No.2 Lonicera Japonica"

目的:考察五种干燥方法对"武当二号金银花"中总黄酮成分的影响。方法:分别采用清蒸+烘干法、微波+干燥法、阴干法、烘干法、晒干法对"武当二号金银花"进行干燥,采用紫外分光光度法测定总黄酮含量,考察不同干燥方法对"武当二号金银花"中总黄酮含量的影响。结果:总黄酮的含量的高低为蒸干法>微波烘干法>烘干法>阴干法>晒干法。结论:"武当二号金银花"的干燥方法以蒸干法、微波烘干法为佳。

Objective To investigate the effects of five drying methods on the total flavonoids in the ＂ Wudang No.2 Lonicera japonica＂. Methods ＂ Wudang No.2 Lonicera japonica＂ dried by steaming ＋ drying method,microwave ＋ drying method,shade drying method,drying method and sunlight drying method. The content of total flavonoids was measured by ultraviolet spectrophotometry,and the effects of different drying methods on total flavonoids content in ＂ ＂ Wudang No. 2 were investigated.Results The content of total flavonoids is the steamed drying methodmicrowave drying method drying methoddry methodsun drying method. Conclusion The drying method of ＂ Wudang No.2 Lonicera japonica＂ is preferably performed by stream drying or microwave drying.
