| Abstract: | Polyphenols was extracted from pomegranate husk by ultrasonic extraction method.The influences of alcohol volume fraction,particle size of pomegranate husk,extraction time,extraction temperature and ratio of material to solvent on extraction rate were investigated.The optimum extraction conditions were obtained through single factor experiment and orthogonal experiment as follows:alcohol volume fraction of 40%,pomegranate husk of 40 mesh,extraction time of 50 min,extraction temperature of 30 ℃,ratio of material to solvent of 1∶15(g∶mL).Under above conditions,the average extraction rate was 16.44%.Compared with traditional refluxing extraction method,ultrasonic extraction method cost shorter time and less enery with higher extraction efficiency. |
