目的 优选盐制余甘子的炮制工艺。方法 以没食子酸、槲皮素、醇溶性浸出物和水溶性浸出物为指标，对食盐用量、加水倍数、浸泡时间和干燥温度4个影响因素进行考察。采用L₉(3⁴) 正交试验及综合评分法优选余甘子的盐制最佳工艺。结果 优选最佳盐制工艺条件为用余甘子药材量3%的食盐，加入余甘子药材1.2倍量的水，浸泡10 d，90 ℃烘干。结论 优选出的最佳炮制工艺稳定、合理可行，可用于指导规范化生产。

Objective To choose the optimal salt-processing technology for Phyllanthus emblica. Methods Taking the contents of gallic acid, querectin, ethanol soluble extraction, and water-soluble extract as the indexes, the factors of brine concentration, watering multiple, soaking time, and drying temperature were investigated. L₉(3⁴) orthogonal design and comprehensive score were used to optimize the salt-processing technology for P. emblica . Results The optimal salt-processing technology was: 3% salt, adding 1.2- fold water, soaking for 10 d, and drying under 90 ℃. Conclusion The optimal salt-processing technology is stable, reasonable, and feasible, and could be used to guide the standardization production.
