环草石斛药材不同加工方法的比较

目的:研究4种不同加工方法加工的环草石斛药材的质量区别,找出最适宜的药材加工方法。方法:采用阴干、不同温度烘干、边搓边烘、烫后边搓边烘的加工方法对环草石斛药材进行加工,加工后的药材进行多糖含量测定和比较。结果:加工后环草石斛药材的折干率在36%左右,开水烫后边搓边烘的加工方法测得的多糖含量为16.39%,明显高于其余几种方法。结论:环草石斛药材加工采用开水烫后边搓边烘的方法,有利于药材的干燥和有效成分的保留,这一结果为2005版药典中石斛的加工方法提供了科学依据,并为其加工提供了量化指标。

The Comparison of Different Processing Methods of Dendrobium loddigesii

OBJECTIVE: To study the 4 different processing methods of Dendrobium loddigesii. and find a optimal method. METHODS: Drying in the shade, fire drying at different temperature, twist and fire drying, to scald by boiling water then twist and fire drying were used to process D. loddigesii and determined the content of polysaccharide after processed. RESULTS: The rate of dryed medical material was about 36%, and the content of polysaccharide was 16.39% which was scald by boiling water then twist and fire drying was higher than others. CONCLUSION: The method scald by boiling water then twist and fire drying is good for medical materials dried and the remaining of active component. It provide a scientific evidence to Chinese Pharmacopoeia 2005 and offer quantization index to the processing of Dendrobium loddigesii.
