Supercritical CO_2 Extraction Process Of Pine Pollen

Shao Xingjun,Yang Qin,Jiang Yunyun,Yu Shumei (Technology Engineering Center for Supercritical Natural Medicines of Jiangsu Province,Zhengjiang 212009 Nucell Bio-Technology Co,Ltd,Zhengjiang 212009)  
This experiment was the single factor and orthogonal experimental research on supercritical CO_2 extraction process of pine pollen were optimized.Experimental results show that the factors on the pine pollen yield of active ingredients in sequence are:pressure temperature time solid to liquid ratio.Moreover,the optimum pressure,temperature,time and the liquid-solid ratio are 30 MPa,36t,4 hours and 1:1,respectively,the extraction yield reached 11.28%.
