Abstract:
AIM: To establish the quality standard for Qingdai Powder (Indigo Naturalis, Radix Glycyrrhizae, Borax, Boreolum Syntheticum, Herba Menthae, Rhizoma Coptidis, Catechu, etc.) METHODS: Indigo Naturalis, Borneolum Syntheticum, Rhizoma Coptis, Radix Glycyrrhizae were indentified by TLC, and the content of indigo was determined by HPLC. RESULTS: Indigo Naturalis, Borneolum Syntheticum, Rhizoma Coptis, Radix Glycyrrhizae could be indentified by TLC. Indigo showed a good linear relationship at a rang of 27.35～ 410.25ng, r=0.9997. The average recovery of indigo was 99.03%( n =6) and RSD was 2.14%. CONCLUSION: The method is simple, accurate and high specificity with good repeatability. The method can be used for quality control of Qingdai Powder.
