ABSTRACT
AIM:
To establish the method of determining procyanidin B2 content in grape seed extract by HPLC.METHODS:
The determination was carried out with ZORBAX SB-C_ 18 column. The mobile phase consisted of acetonitrile-2% acetate buffer under the gradient elution condition, detection wavelength was at 280nm.RESULTS:
There was a good linear relationship between the peak area and concentration in the range of 1~30 ?g/mL for procyanidin B2. The average of procyanidin B2 (n=5) was 99.29% and RSD=1.64%, respectively.CONCLUSION:
The method is simple, accurate, reproducible and can be used for assay of procyanidin B2.
