湿式超微粉碎提取三七总皂苷及粒径对提取率的影响

Wet Ultrafine Grinding Technology Extracted the Total Saponins from Panaxnotoginseng and the Relationship between the Size and the Extraction Rate

目的研究湿式超微粉碎法与传统提取方法对三七总皂苷提取的影响及粉碎粒径与提取率的关系。方法以三七总皂苷为指标,高效液相法测定提取率以及粒径分布仪测定粒径。结果湿式超微粉碎法提取率较普通回流法略有提高,但普通回流法需要2 h,而湿式超微粉碎法只需10 min,节省了时间;超微粉碎随时间的增加,粒径越来越小,但提取率并没有增加。结论湿式超微粉碎与提取同步完成,极大的提高了提取的效率;粉碎粒径与提取率并不呈现比例关系。

Objective To study the wet AMD to crush the traditional method of extraction method PNS from the impact and crush size and the relationship between the extraction rate. Method PNS as an indicator,determination of extraction rates,and to measure the particle size distribution. Results Wet UGT to crush extraction rate of return than ordinary law increased slightly, but the common law needs to return two hours, and the method of wet UGT to crush 10 minutes, saving time; UGT to crush the increase with time, size getting smaller and smaller,but the extraction rate has not increased. Conclusion The wet UGT to crush and extract synchronization completed ,greatly improving the efficiency of the extraction ;smash the size and the extraction rate does not show the proportion relations.
