Abstract
The optimization technology for extraction Resveratrol from Polygonum cuspidatum were studied. The effect of complex enzyme, cellulose, β - glucosidase and Polydatin special enzyme on the extraction was investigated. The experiment results show that the content of resveratrol by β - glucosidase was the highest. The single factor experiment design was used and resveratrol was choosen as the index to study the key factors affecting the enzymic hydrolysis, such as substrate concentration, enzyme dosage, pH, the enzymic hydrolysis temperature and the time. The optimum enzymic hydrolysis procedure was; pH was 5, the amount of the β - glucosidase was 3% , the temperature was 40℃ , and the enzymic hydrolysis reacting time was 10h. The technology improves the extracting rate and is suitable for mass production.关键词
