Abstract:

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.

Key words: powder, quality evaluation, Bletilla striata, polysaccharide
