Determination of Dracorhodin in Gushang Dieda Zhitong Capsules by HPLC

Objective： To establish a method to determine dracorhodin in Gushang Dieda Zhitong capsules by HPLC. Methods： An HPLC method was used for the determination of dracorhodin, a Shimadzu VP-ODS C18 column was used，and acetonitrile-0.05 mol·L-1 sodium dihydrogen phosphate solution（35∶65）was the mobile phase．The flow rate was 1.0 ml·min-1．The detection wavelength was at 440nm. Results：The linear range of dracorhodin was 0.047-0.234 μg（r=0.999 9）.The average recovery was 99.9% with RSD of 1.5%. Conclusion：The method is simple, rapid, accurate and specific. It can be used in the quality control of Gushang Dieda Zhitong capsules.
