摘要: 本文根据中草药有效成分含量低,结晶性组分易堵塞管道等问题,以银杏叶粗提物为原料,通过单因素实验的方法,探讨萃取结晶压力、温度、时间对超临界CO2萃取结晶银杏萜内酯的纯度影响。实验结果表明:在萃取结晶为20MPa,温度为55℃,时间为90min条件下,银杏萜内酯纯度达到85%以上。

Abstract: Based on less content of active ingredients of Chinese herb, crystal ingredients jamming pipeline, and so on, we took extractof ginkgo biloba L. as experimental material to investigate the effect of extracting and crystallizing pressure, temperature and timeon the purity of ginkgolides extracted and crystallized by supercritical CO2 via single factor experiments. The results showed thatextracting and crystallizing pressure 20MPa, temperature 55℃, time 90min, the purity of ginkgolides was more than 85%.
