Objective:To study on the material basis of antioxidant activity of Sanguotang by establishing its HPLC fingerprints and determining its antioxidant activity. Method:Nine samples of Sanguotang were extracted by reflux method and orthogonal test.Fingerprints were analyzed by HPLC
1
1-diphenyl-2-trinitrophenylhydrazine(DPPH) assays was established to determine the antioxidant activity of Sanguotang.The spectrum-effect correlation was investigated by partial least square method
and the active chromatographic peaks were screened out. Result:HPLC fingerprints of Sanguotang was established
and the similarities were more than 0.90.And 27 common peaks were identified
the variable projection importance(VIP) values of these 12 peaks were more than 1.0
indicating that the 12 peaks played an important role in the antioxidant activity of Sanguotang.By comparison with the reference substances
the peak 5
10
20
23
27 were determined as gallic acid
gallocatechin
corilagin
epicatechin gallate and ellagic acid
respectively. Conclusion:The antioxidant activity of Sanguotang is the result of synergistic effect of multiple components
its material basis can be analyzed by spectrum-effect relationship
which can provide basis for the quality control of Sanguotang.
