    摘要:

    比較了12種大孔吸附樹脂對板栗殼中原花青素的吸附與解吸性能，在靜態(tài)吸附研究基礎(chǔ)上,，篩選出效果較好的樹脂進行動態(tài)試驗,，并對所得組分原花青素含量及其相對分子量進行分析。結(jié)果表明,，AB-8大孔吸附樹脂分離純化CSPCs效果最佳,，上樣質(zhì)量濃度為1.864mg/mL，流速為2 mL/min,；當(dāng)用體積分數(shù)為50%乙醇以1 mL/min的流速洗脫4個柱體積時,，CSPCs 的累積回收率可達94.2 %，含量為89.8%,。經(jīng)質(zhì)譜分析,，分子量范圍為289.4~1154.9，聚合度在4以內(nèi),。

    Abstract:

    With the aim to separate and purify procyanidins from chestnut-shells (CSPCs) by macroporous resin, twelve macroporous resins were tested for their static adsorption/desorption performance towards CSPCs. Based on the static adsorption experiments, the suitable macroporous resin was screened to carry out dynamic adsorption experiment, the content and the relative molecular weight of CSPCs were analyzed. The results showed that AB-8 was the optimal macroporous resin for separating and purifying CSPCs, the optimum separating condition was as follows: the mass concentration and the sampling rate were 1.864 mg/mL and 2 mL/min, respectively. The total recovery of CSPCs reached 94.2% eluted with 50% ethanol of 4 BV at a flow velocity of 1 mL/min, and the content of the total CSPCs in the obtained fine product was 89.8%. Analysis of CSPCs by ESI-MS demonstrated the molecular weight ranged from 289.4 to 1154.9 (M+H) within 4 of average polymeric degree.
