| 摘 要： | 以大黄素为指标对虎杖中的有效成分进行超临界流体CO2萃取。用正交设计法考察了最优萃取条件。影响超临界流体萃取率的主要因素依次是:动态流量、温度、压力、时间;确定了大黄素的最佳萃取条件是:萃取压力25 MPa,萃取温度55℃,动态流量8 kg/h,萃取时间30 m in。超临界流体萃取大黄素的提取率达0.36%。 |
| 关 键 词： | 超临界流体萃取 正交试验 虎杖 大黄素 |

| Abstract: | Study on extraction of effective components of polygonum cuspidatum sieb.Et Zucc.by supercritical fluid CO_2 with the reference of emodin.The optimum extraction condition for emodin was determined by orthogonal design.The optimum extraction condition: pressure 25 MPa,temperature 55℃,CO_2 flow rate 8 kg/h,extraction time 30 min.The extraction rate of emodin by supercritical fluid is(0.36%). |
| Keywords: | supercritical fluid extraction orthogonal test polygonum cuspidatum sieb Et Zucc emodin |
