RESUMEN
Objective:To establish the quality control standard for corydalis B in Qizhiweitong Tablets.Methods:corydalis B content in Qizhiweitong Tablets was determined by TLC-scanning with a mixture of n-hexane-chloroform-methanol(10∶6∶1) as a developer and dual wavelength reflection sawtooth scanning.Results:The methodological study showed that a good linear correlation existed in the range of 0.1942 to 0.9710?g of the sample applied, and the average recovery was 97.63% (n=5).Conclusion:Trials indicate that this method is reliable, accurate and simple.
RESUMEN
Objective: To determine oleanolic acid in Fructus Mume. Methods: HPLC with Shim-pack CLC-ODS column was used. The mobile phase was composed of MeOH-H 2O-HOAc-TEA (85∶15∶0.04∶0.02). The flow rate was 0.8mL?min -1 and the detection wavelength was at 204nm. Results: It showed that a good linear relationship existed in the range of 0.8864～4.432?g of oleanolic acid. Its average recovery was 97.03%. RSD was 0.25% (n=5), respectively. Conclusion: This method is quick, accurate and can be used for the determination of oleanolic acid of Fructus Mume.
