Abstract
Objective To establish the qualitative and quantitative methods to improve its quality standard of Dieda Tablets. Methods TLC was applied to the identification of Notoginseng Radix et Rhizoma, Dipsaci Radix, Draconis Sanguis, Paeonia Radix Alba, Paeonia Radix Rubra, Moutan cortex, Aurantii Fructus ImmaTurus and Drynaria Rhizoma; HPLC was applied to determinte asperosaponin VI; the analytical column was KromasilTM C18 column ( 150 mm × 4. 6 mm, 5μm ); the mobile phase was acetonitrile-water at the flow rate of 1. 0 mL/min;the detection wavelength was 212 nm;and the column temperature was 35 ℃. Results The spots in the TLC were clear and could be well separated, the blank test showed that other medicine herbs had not interference with the main one;The calibra-tion curve of asperosaponin VI showed good linearity in the range of 0. 347 3-2. 430 8 μg ( r=0. 999 9 ) . The average recovery was 99. 14%, RSD was 1. 34%( n=9 ) . Conclusion The established methods are accurate, reliable, specific and with good reproducibility. It can be used for the quality control of the Dieda Tablets.关键词
