Abstract: The solubility,UV spectrum,heat and light stability and antioxidation activity of oligomeric proanthocyanidins (OPC) extracted from grape seeds were studied.The results showed that OPC had good water solubility,light and thermal stability(T≤60℃)and tis λmax was 278nm.The antioxidation activity of OPC.Comparing the same amount addition of OPC,VC or VE into lard,OPC was superior to VC or VE in antioxidation.When a mixture of OPC,VC and VE was used,a remerkable synergistic antioxidation was obserced.

Key words: grape seeds, oligomeric proanthocyanidins, antioxidation
