目的 研究大孔吸附树脂纯化黄连总生物碱的工艺。方法 采用LD605、D101、DA201、NKA-9、AB-8大孔吸附树脂对黄连总生物碱进行吸附纯化。以总生物碱的收率、质量分数为考察指标综合评价。结果 AB-8大孔吸附树脂具有最佳的吸附洗脱参数,其动态饱和吸附-洗脱量达1.23mg/g,2倍体积蒸馏水、2倍体积40%乙醇依次洗脱,总生物碱收率为85%,质量分数为80%。结论 AB-8大孔吸附树脂对总生物碱综合性能较好,适合于黄连总生物碱的分离纯化。

Objective To study the technology for purification of total alkaloids from Rhizoma Coptidis by maeroreticular adsorbent resin.Methods LD605,D101,DA201,NKA-9,and AB-8 types of macroreticular adsorbent resins werre used to separate and purify the total alkaloid from Rhizoma Coptidis.The yields and purities of the products were compared as indexes.Results AB-8 Type macroreticular adsorbent resin had optimum adsorption and elution parameters with its dynamic saturated adsorption ratio up to 1.23 mg/g.After eluted with 2 BV of distilled water and 2 BV 40% ethanol,the yields of total alkaloid was 85%,and content was 80%.Conclusion The AB-8 type macroreticular resin showsa better comprehensive adsorption property and can be used to separate and purify the total alkaloids from Rhizoma Coptidis.
