摘要: 采用正交试验法优化CO2超临界提取葛渣中葛根素的工艺研究。在单因素试验的基础上,选择萃取投料量、萃取温度、萃取压力、萃取时间四个因素,进行L9(34)正交试验设计,评估了这些因素对葛根素提取率的影响。实验结果表明最佳工艺参数为投料量50 g,萃取温度55 ℃,萃取压力16 MPa,萃取时间90 min。在此条件下,葛渣中葛根素的萃取率为82.5%。

Abstract: The CO2 supercritical extraction process of puerarin from Radix puerariae residue was optimized using orthogonal experiment.Based on single factor experiments, sample amount,extraction temperature,extraction pressure and time were selected for L9(34) orthogonal tests using the extraction yield of puerarin as index.The results indicated that the optimal extraction conditions were sample amount of 50 g,extraction temperature of 55 oC,extraction pressure of 16 MPa and extraction time of 90 min.Under the optimized conditions,the extraction yield of puerarin was up to 82.5%.
