| Summary: | 碩士 === 國立高雄應用科技大學 === 化學工程系碩士班 === 96 === The oligomeric proanthocyanidins (OPC) exhibit the free radical scavenging and antioxidant activity. It has been widely applied to food, drinks, cosmetics and other healthy products. This study demonstrated that the proanthocyanidins is extracted from grape seeds by a boiling citric solution. The extracts are passed through a column HP-2MG. The oligomeric proanthocyanidins (OPC) is obtained. The yield reaches 0.7%. FTIR and HPLC examinations showed that the OPC purity is very high. This process is simple and is proceeded by the non-toxic solvent.
