    Abstract:
    OBJECTIVE: To establish a HPLC method for determination of 4 components in different varieties of vinegar backed Rhizoma Curcuma. METHOD: The method was established by using an Elite Hypersil ODS2 column (4.6 mm x 250 mm, 5 microm). The mobile phase comprising acetonitrile (A) and water (B) was used to elute the targets in gradient elution mode. Flow rate and detection wavelength were set at 1 mL x min(-1) and 214 nm, respectively. The column temperature was 25 degrees C and the injection volume was 10 microL. RESULT: All calibration curves showed good linearity with r > 0.999 5. Recoveries measured at three concentrations were in the range of 97.27% - 99.27% with RSD < 3%. CONCLUSION: The validated method is simple, reliable, and successfully applied to determine the contents of the selected compounds in vinegar backed Rhizoma Curcuma. The results of the determination showed that contents of the four components in vinegar backed Curcuma wenyujin were relatively high.
