Abstract:
OBJECTIVE: To determine the content of dracorhodin in Diedaqili Tablets by HPLC. METHODS: The separation was performed on Diamonsil TM C18 column. The mobile phase consisted of acetonitril-0. 05mol? L-1 sodium biphosphate solution ( 45∶ 55) with detection wavelength at 440nm and flow rate at 1. 0mL? min-1. RESULTS: The calibration curve of dracorhodin was linear within the range of 0. 122～ 0. 854? g ( r=0. 999 9) , with average recovery at 101. 4% ( RSD=0. 91% ) . CONCLUSION: This method is simple, reliable and reproducible, and suitable for the quality control of Diedaqili Tablets.
