摘要
目的通过对23种大孔吸附树脂筛选,寻找适用于纯化小蓟中咖啡酸酯类成分的大孔吸附树脂,为从小蓟中工业化生产咖啡酸酯类成分提供依据。方法采用23种大孔吸附树脂对小蓟提取物进行吸附纯化,以总咖啡酸酯收率和纯度作为指标综合评价。结果23种吸附树脂中,以树脂HPD-100吸附洗脱的总咖啡酸酯的收率最高为87.6%、纯度为52.2%。结论HPD-100树脂综合性能良好,适用于小蓟中咖啡酸酯类成分的纯化。
Objective To search for the method used in enriching caffeates in Cirsium setosum by macroporous adsorption resin, 23 types of macroporous adsorption resin were optimized, which could provide the industrial production of caffeates with the theory basis. Methods The adsorption and elution ratios, product purity and yield, as total indices, were comprehensively evaluatued by 23 types of macroporous adsorption resin in enriching the extracts in C. setosum. Results The product purity and yield of caffeates by the HPD-100 type macroporous adsorption resin were the highest and up to 52.2% and 87.6%. Conclusion The HPD-100 type macroporous adsorption resin shows better comprehensive adsorption property. It is available for the enrichment of caffeates in C. setosum.
