| Abstract: | Through the ultrasonic extraction of pine bark proanthocyanidins and experiment of membrane separation and purification technology, inspected the influence of single factor such as ultrasonic extraction temperature, liquid ratio and extraction time on proanthocyanidins yield, the influence of test pressure, tested the working pressure of ultrafiltration membrane and the optimum process parameters of molecular weight cut - of. The result showed that the optimum parameters of pine bark proanthocyanidins extracted by the ultrasonic strengthening countercurrent are. liquid ratio 1： 12, ultrasonic temperature 60~C, extracting time 30 min; the purification process parameters of the ultrafihration membrane are, membrane pressure is 0. 2 MPa, molecular weight cut - of 5000, the pine bark proanthocyanidins content can reach more than 95% |
