摘　　要：以原花青素平均分子量为指标,醋酸为水解介质,对纯化工艺中所分离的高聚体原花青素(PPC)的水解工艺进行了优化研究。结果表明,在80℃下,用50%的醋酸水解提取30min,葡萄籽中提取纯化的高聚体原花青素平均分子量由1831.60下降到1108.80,下降了722.8个单位。With the average molecular weight of proanthocyanidins as index,acetic acid as hydrolysis medium,the hydrolysis technology of high ploymeric proanthocyanidins （PPC）isolated by purification technology was optimized and studied. The results indicated that at 80 ℃,the average molecular weight of purified PPC extracted from grape seeds,which were hydrolyzed with 50 % acetic acid for 30 min,was decreased from 1 831.60 to 1 108.80 and the decrement was 722.8 units.
