超声辅助提取功劳木中盐酸小檗碱工艺研究

为了优化功劳木中盐酸小檗碱的超声波辅助提取工艺,采用单因子实验和L9(34)正交实验设计,研究了超声时间、超声功率、乙醇浓度、提取温度、液料比、筛分目数对功劳木中盐酸小檗碱提取的影响。结果表明,影响盐酸小檗碱得率的主次因素为乙醇浓度,液料比,超声时间,超声功率;经正交实验确定功劳木盐酸小檗碱最佳提取工艺条件为:乙醇浓度80%,超声提取时间为30min,超声功率选择为500W,液料比为9,经5次平行实验验证,该实验工艺稳定可靠,与对照实验相比,盐酸小檗碱得率可提高56.1%。

Ultrasonic-assisted extraction of berberine from Caulis Mahonia

For optimal parameters of extraction condition for berberine of Caulis Mahonia,effects of ultrasonic extraction time,ultrasonic extraction temperature on berberine yield were studied through single factor experiments and orthogonal experiments. The results indicated that the effect sequence of four main factors for berberine yield were as follows:ethanol concentration,liquid-to-solid ratio,ultrasonic extraction time,ultrasonic power. The optimal extraction conditions were as follows:80% ethanol as the solve...
