A Quality Standard Study onQingyan Granule
摘要
Abstract
Objective To establish the standard for quality control ofQingyan Granule. Methods The chief components of the preparation, Sophora Tonkinensis radix et rhizoma, Adenophorae radix, Lonicera japonica caulis, and Ophiopogonis radix were identified by TLC qualitatively. The contents of licorice glycosides and glycyrrhizic acid were determined by HPLC. The separation was performed on Thermo Syncronis C18 column (4.6 mm×250 mm, 5μm) with mobile phase consisted of acetonitrile with 0.05% phosphoric acid solution (A)-0.05% phosphoric acid solution (B), and gradient elution (0-8 min, 19%A;8-35 min, 19%→50%A). Detection wavelength was 237 nm, and flow rate was 1 mL/min.Results The spots in TLC were clear. There were spots with same color on the corresponding location of reference substance and reference herbal, negative control without interference. The linear range for licorice glycosides was 0.05-0.5μg (r=0.999 9). The average recovery was 99.97%, RSD=1.74% (n=9). The linear range for glycyrrhizic acid was 0.1-2μg (r=0.999 9). The average recovery was 99.74%, RSD=1.28% (n=9). Conclusion The method is simple, accurate, with high reproducibility, which can be used for quality control ofQingyan Granule.关键词
