摘 要:目的优化育亨宾树皮中育亨宾的提取工艺。方法以育亨宾为测定指标,建立HPLC检测方法;通过单因素考察了不同溶剂、酸水体积分数、料液比、提取时间和提取温度对育亨宾提取率的影响;在单因素实验的基础上,采用正交实验L_9(3~4)确定最佳提取工艺。结果育亨宾质量浓度在10~800μg·mL^(-1)(r=0.999 9)范围内呈良好的线性关系;最佳提取工艺为22倍质量分数0.2%的盐酸水溶液,100℃提取3次,每次1.5h。结论该提取方法简单可行,可得到质量均一稳定的育亨宾提取物。Objective To optimize the extraction process of yohimbine from yohimbine bark yohimbine. Methods HPLC detection method was established for yohimbine simultaneous determination.The effects of different solvents,acid water volume fraction,solid-liquid ratio,extraction time and extraction temperature on the extraction rate were investigated.On the basis of single factor experiment,the optimal extraction process was determined by an orthogonal test L 9(3 4). Results Yohimbine showed a good linerity in the range of 10-800μg·mL^-1( r =0.999 9);the optimal extraction conditions were concluded as follows:22 times amount of 2 mL·L^-1hydrochloric acid water as extractant,extraction 3 times (each time 1.5 h) and extraction temperature 100 ℃. Conclusion It was simple,stable and suitable for mass yohimbine production.
