大孔吸附树脂分离纯化黄连总生物碱的工艺研究

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。

Separation and purification of total alkaloid from Rhizoma Coptidis by macroreticular adsorbent resin

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.
