Results The purification effect was satisfactory when the concentration of original solution of the extract of Cacumen Platycladi was 0.20 gmL^(-1), the loading amount was 0.375 g of Cacumen Platycladi per 1 mL of wet AB-8 resin, the adsorption velocity was 1 mLmin^(-1), the eluant was 70% alcohol being 4 times as much as the resin volume, and the elution velocity was 2 mLmin^(-1). AB-8 resin could be used for 3 times repeatedly after being reproduced by 95% of ethanol and 1 moLL^(-1) of natrium hydroxydatum. The remaining rate of the total flavonoids and quercitrin was over 70% and 95% respectively, and the remaining rate of peaks 1~3 was over 90%.

结果 AB-8型大孔吸附树脂纯化效果较好，最佳工艺条件为：上样液浓度为含生药量0.20gmL^(-1)，上样量为每1mL湿树脂上样0.375g生药，吸附速率为1mLmin^(-1)，洗脱液为4倍柱体积的70%乙醇，洗脱速率为2mLmin^(-1)；树脂经95%乙醇和1moLL^(-1)氢氧化钠溶液再生后，可重复使用3次。
