- W2393180740 abstract "Objective: To establish the method to determine simultaneously the concentration of doxyschizandrin and schisandrin B in Hugan tablets. Method: The sample was extracted with methanol through supersonic wave, and then filtered. RP - HPLC was used for the determination of doxyschizandrin and schisandrin B in Hugan tablets. The chromatographic procedure was carried out using DiamonsilTM18(250 mm ×4. 6 mm,5 μm) as an analytical column and a mixture of 70 volume of acetonitrile,30 volume of water,0. 1 volume of acetic acid as mobile phase at a flow rate of 1. 0 mL *?min-1. The detection wavelength was set at 254 nm. Results:The peaks of deoxyschizandrin and schisandrin B appeared on about 19 and 26 minutes and the resolutions of them were both more than 1.5. Their linear ranges were between 0. 02 and 0. 12 μg( r = 0. 9999) and between 0. 048 and 0. 288 μg( r = 0. 9999) , respectively. The average recoveries of both components were 97. 25% and 97. 07% , respectively. Conclusion:This method was found to be sensitive, quick and accurate for the simultaneous measurement of deoxyschizandrin and schisandrin B in Hugan tablets." @default.
