摘　　要：目的:考察中药水煎液不同前处理方法对大孔树脂吸附分离效果的影响,确定其内在规律。方法:以红景天水煎液为对象,红景天苷含量为指标,分别采用一次醇沉、二次醇沉、加入沉淀剂、沉淀剂加醇沉、离心5种精制处理方法,考察对大孔树脂吸附效果的影响。结果:二次醇沉法及沉淀剂合并醇沉的方法对水煎液的精制效果最佳,同时对大孔树脂的分离效果也最佳。结论:中药水煎液使用不同的前处理方法对大孔吸附树脂分离效果具有显著影响。Objective： Study on adsorption and separation effect of Chinese medicine decoction by different pre-treatment methods with macro-porous resin,and determined its inherent laws.Method： The content of Salidroside as an indicator to select decoction of Rhodiola herb with once-alcohol precipitation,twice-alcohol precipitation by adding precipitant,precipitant added with alcohol and centrifugation procedure.In order to observe different methods of decoction refined have an effect on macro-porous resin adsorption.Result： The effect of purity of the water extract of Rhodiola and macro-porous resin separation is the best by the way of using twice-alcohol precipitation and adding precipitant and alcohol precipitation.Conclusion： Chinese medicine decoction by different pre-treatment methods had significant impact on adsorption and separation of macro-porous resin.
