| Abstract
|
| [Objective] To establish the quality standard of QingYi Tablets (Radix Et RhiZoma Rhei,Radix Paeoniae Alba, Rhizoma Picrorhizae).[Methods] Radix Et RniZomu Rhei,Rellix Pheouiae Alba and Rnizoma Picrorhizal were identified by TLC. The content of Baicalin was determined by HPLC. The separation was performed on C18 Column with methanol-Water-Phosphorus acid (47:53:0.2) as a mobile phase. The flow rate was 1.0mL/min, detection Wavelength at 280 nm.[Results] The developed TLC spots were quite clear. The content of Baicalin can be determined by HPLC. The linearity of Baicalin was good in the range of 0.27-1.08ug. (r=0.9998) The average recovery of Baicalin was 99.46%, RSD=0.39% (n=6). [Conclusion] The method was simple, reliable, accurate and can be applied as the quantity control method of QingYi Tablet. |
