摘要
为建立白及粉末饮片的质量评价方法,以不同产地的10批次白及粉末饮片为研究对象,建立并改进了其薄层色谱鉴别方法,并采用蒽酮-硫酸法测定白及粉末饮片中的白及多糖质量分数,同时对其显微鉴别以及水分、总灰分和酸不溶性灰分质量分数的测定进行了研究和归纳。本实验建立的方法简单快速、重复性好,能够对白及粉末饮片质量进行有效、科学的评价。
To establish the quality evaluation method of Bletilla striata powder, ten batches of samples from different areas were adapted to analysis. The identification method based on thin layer chromatogram （TLC） was improved, while the method with anthrone-sulfuric acid coloration was established to determine the polysaccharide in Bletilla striata powder. Meanwhile, the contents of microscopic, moisture, total ash, and acid insoluble ash in Bletilla striata powder had been studied and summarized. This method is convenient and stable so that it can be effectively and scientifically used for the quality evaluation of Bletilla striata powder.
