摘要
在超声波辅助条件下,采用四元二次正交旋转组合设计研究乙醇体积分数、液料比、时间、温度4个因素对药桑花青素提取效率的影响,用DPS7.05软件分析得出4个因素的回归方程。结果表明,超声波辅助提取最佳工艺条件为:乙醇体积分数范围52.46%～55.93%、提取液料比范围39.51:1～42.43:1(mL/g)、提取时间范围27.77～32.23min、提取温度范围50.18～52.4℃,在此工艺条件下花青素提取效率均能达到67%以上。
A quadratic orthogonal rotation combination design was used to explore the effects of ethanol concentration,material-to-liquid ratio,extraction time and extraction temperature on extraction rate of anthocyanidin from black mulberry（Morus nigra L.） by ultrasonic-assisted extraction.A regression equation was established using DPS7.05 software.The optimal extraction conditions were found to be 52.46%-55.93% ethanol as extraction solvent at a liquid-to-material ratio of 39.51：1-42.43：1（mL/g） for 27.77-32.23 min of extraction at 50.18-52.4 ℃.Under these conditions,the extraction rate of anthocyanidin was more than 67%.
