ABSTRACT
Objective:
To establish the method of determination of the contents of Danshensu and Protocatechuic aldehyde in Huoxue Mixture simultaneously by RP HPLC.Methods:
The determination was carried out with Inertsil ODS column. The mobile phase consisted of methanol 0.5% HAc (22∶78) and UV detection wavelength was 280nm.Results:
The average recovery of standard addition were 96.7%, RSD =1.12% ( n =5) for Denshensu, and 97.0 %, RSD =1.53% ( n =5) for Protocatechuic aldehyde, There was a good linear relationship between the absorption area value and the concentration in the range of 1.25~10?g for Deshensu and 0.25?g~2.0?g for Protocatechuic aldehyde.Conclusion:
The method is simple, acurate, reproducible and can be used for content determination of Huoxue Mixture.
