| Abstract: | This paper studied extraction process of oligometric proanthocyanidins (OPC) from grape-seed, using water, heat water, mixture of acetic ether and water or 60% ethanol as extracting agent. The results indicated that extraction yield and product purity of OPC were high when broken grape-seed and dry grape-seed shell degreased by mineral ether were used as raw material, mixture of acetic ether and water was used as extracting agent. Extraction yield of OPC could arrive at 0.4%~0.6%, and quality coefficient is beyond 98%. |
