Title: Study on the Quality Standard of Huangbai Oral Liquid
Abstract: To establish a quality control standard for Huangbai oral liquid,Rhizoma coptidis,Flos lonicerae,Radix scutellariae and charred radix sanguisorbae were identified by TLC.Content of Berberine hydrochloride and Baicalin were determinated by HPLC.The results showed that the TLC identification was highly specific and the spots were clear and focused with good reproducibility.The calibration curve of Berberine hydrochloride was linear in the range of 0.139 to 0.834 μg(R2=0.9999).The average recovery rate was 97.04%,RSD=0.97%(n=6).The calibration curve of Baicalin was linear in the range of 0.235 to 1.41 μg(R2=0.9999).The average recovery rate was 97.64%,RSD=0.71%(n=6).The quality of the preparation could be controlled by qualitative identification of Coptis,honeysuckle,Scutellaria,Sanguisorba carbon and content determination of Berberine hydrochloride and Berberine.
