Abstract: This experiment was conducted to study the effect of grape procyandins (GPC) and its ingredients on the proliferation of peripheral blood lymphocytes (PBLs)of broiler,and to develop the method to screen active ingredients of GPC.Six concentrations (0,0.24,1.2,6.0,30,150 μg/mL) of GPC were chosen to study the best concentration on the proliferation of PBLs of chickens.RT-HPLC was used to gotten chromatograms of GPC,different ingredients were gotten by Real-time fractionation and different ingredients in the best concentration were used to get the best one.The result showed that the best concentration of GPC was 30 μg/mL and the best ingredient fraction was 16 to 25 min.
