Objective:
To establish a mutual mode fingerprint of Curcuma wenyujin for quality control of C. wenyujin.
Methods:
Waters Symmetry C18 column was used; the mobile phase was methanol-water in a linear gradient elution with the flow rate of 1.0 mL/ min, the temperature of column was 30 degrees C; the detection wavelength was set at 215 nm. 10 batches of C. wenyujin from different places and different time were determined, 3 batches of C. phaeocaulis and 3 batches of C. kwangsiensis were determined in the same chromatographic conditions.
Results:
11 mutual peaks in the fingerprint of the 10 groups of C. wenyujin, and the S peak among them represented germacrone.
Conclusion:
Curcuma wenyujin's fingerprints have strong feature and specificity, which can be combined with assaying in the quality control of C. wenyujin.
