ABSTRACT

AIM:

To determine gallic acid,paeoniflorin and safflor yellow in Taohong Siwu Decoction(Semen Persicae,Flos Carthamietc.)

METHODS:

To analyse three constituents by HPLC on a Hypersil BDS C_(18) column and gallic acid detection wavelength was set at 271 nm.The mobile phase was methanol-water(5∶95) (adjusted to pH=3.0 with H_3PO_4) at a flow rate of 1.0 mL/min. Safflor yellow detection wavelength was set at 403 nm.The mobile phase was methanol-water(80∶20) (adjusted to pH=3.0 with H_3PO_4) at a flow rate of 1.0 mL/min. Paeoniflorin detection wavelength was set at 230 nm.The mobile phase was methanol-KH_2PO_4 at a flow rate of 1.0 mL/min.

RESULTS:

Gallic acid showed a good linear relationship at the range of 4.547?10~(-3)-1.455?10~(-1) ?g/?L(r=0.999 3).Paeoniflorin showed a good linear relationship at the range of 0.010-0.200 ?g/?L(r=(0.999 8)) and safflor yellow showed a good linear relationship at the range of 2.34?10~(-2)-7.50?10~(-1) ?g/?L(r=(0.999 4)).The average recoveries were 98.0% for gallic acid,98.4% for paeoniflorin and 99.2% for safflor yellow.The RSD of the method were 1.8%,0.69% and 0.88%,respectively.

CONCLUSION:

The method is proved to be fast,feasible,simple,and can be used for quality control of gallic acid,paeoniflorin and safflor yellow in Taohong Siwu Decoction.
