| Abstract: | Objective To establish a method for the determination of ginsenoside Rg1 in Jiangtangning Capsules . Method Ginsenoside Rg1 was determined by dual-wavelength TLC-scanning method with 525 nm and 700 nm as the detective wavelength. Result There was a good linear relationship from 0. 323 to 2. 584 μg for ginsenoside Rg1r=0. 999 5. The average recovery was 98.06%(RSD=1. 33% ,n = 5). Conclusion The method is simple and accurate and can be used for the quality control of Jiangtangning Capsules. |
