| 摘 要： | AB-8树脂对葡萄籽原花青素具有吸附量大、解吸率高、选择性好等特点,适于分离并得到纯度较高的葡萄籽原花青素。对其分级分离特性的研究表明,采用AB-8树脂吸附分离原花青素,通过逐步提高乙醇浓度(10%～50%)可以将原花青素按聚合度由低到高的顺序依次洗脱下来,从低浓度乙醇洗脱液中可以得到低聚体含量相对较高的原花青素组分,并且可用于原花青素的工业化生产。 |
| 关 键 词： | 葡萄籽 原花青素 AB-8吸附树脂 聚合度 |

| Abstract: | AB-8 resin was selected for the fractionation of grape seed procyanidins for its excellent adsorption and desorption properties,a product with procyanidin content can be obtained by isolation on AB-8 resin.Furthermore,fractionation of procyanidins according to DP was performed on AB-8 resin.By elution with increasing ethanol concentration,procyanidins were recovered according to increasing DP in sequence,fractions with relatively higher content of oligomeric procyanidins can be obtained from elute of low ethanol concentration.This procedure can be further applied to large-scale preparation. |
| Keywords: | grape seeds procyanidins AB-8 adsorbent resin degree of polymerization |
