摘要: 研究了聚酰胺柱层析技术吸附分离葡萄籽原花青素的效果,并对比了分级洗脱产物的清除羟自由基的能力。结果表明,聚酰胺吸附分离原花青素的适宜上样流速为0.45ml/min,上样浓度为5~8mg/ml。用80%丙酮溶液洗脱时,可获得最高的产率。在分级洗脱物中,80%和40%丙酮洗脱物的清除•OH能力最强,其次是60%浓度的丙酮洗脱液,各产物的抗氧化性均好于儿茶素。

Abstract: The effects on separation and purification grape seed extracts by polyamide column chromatography, as well as the capacity of eliminating• OH of each segment were studied. The results showed that the suitable velocity of flow and the concentration of sample loading are 0.45 ml/min and 5~8 mg/ml respectively. The highest yield can be obtained when washing with 80% acetone. Among four washing segments, the products coming from 40% acetone and 80%acetone during washing has showed much high capacity in eliminating• OH, then came the 60% acetone. However, the capacity of eliminating• OH of each segment is better than that of catechin.
