Abstract:Objective:To provide a reference of reasonable quality control standards through a comparative study of the four fingerprints of four origin plants of Curcumae Radix. Method: The separation was performed on HP-5 0.32 μm×0.32 mm×30 m column,hydrogen flame ionization detector (FID); injector temperature was 280 ℃, detector temperature was 300 ℃; the column oven was begun at 125 ℃,then programmed from 125 ℃ to 170 ℃ at 3 ℃·min-1, then programmed from 170 ℃ to 260 ℃ at 9 ℃·min-1 and final, held 0 min. Result: To analyse 20 batches of volatile oil, the fingerprints of four origin plants of Curcumae Radix were established. The fingerprint similarity value of the Curcuma longa and C.wenyujin is above 0.95; the fingerprint similarity value of the C.phaeocaulis is above 0.99; the fingerprint similarity value of the C.kwangsiensis is about 0.90. Conclusion: It displayed marked differences between four origin plants of Curcumae Radix volatile oil chemical constituents and everyone's fingerprint could describe own chemical constituents. So we provide the data support for establishing scientific quality control standards of Curcumae Radix.
