Abstract:
Objective: To establish the quality standard for Yuhuang sprays. Methods: Berberine hydrochloride in Yuhuang sprays was qualitatively identified by TLC and determined by UV. The Vanillin-H2 SO4 method was employed for the determination of condensed tannins. Results:The spots obtained from the sample solutions showed the same color as those from the reference substance solution without interference from the negative sample. The calibration curve of berberiny hydrochloride was linear within the range of 1. 13-13. 60μg·ml-1(r=0. 999 9), and the average recovery was 99. 68% with RSD of 1. 53%(n=9). The calibration of catechin was linear within the range of 0. 03-0. 30 mg· ml-1(r=0. 999 3), and the average recovery was 99. 6% with RSD of 1. 76%(n=9). Conclusion:The method can be used in the quality control of Yuhuang sprays.
