摘要: 研究水、50%甲醇溶液和β-环糊精溶液对葡萄叶中多酚和白藜芦醇提取效果的影响,并采用分子对接方法分析β-环糊精与白藜芦醇之间的相互作用。结果表明:50%甲醇溶液提取所得多酚的提取量最大,而β-环糊精所得白藜芦醇的提取量最大;β-环糊精的疏水性空腔可以容纳白藜芦醇分子,并通过氢键的形成维持复合物的稳定。通过单因素和响应面优化试验对β-环糊精提取葡萄叶中白藜芦醇的工艺参数进行分析和优化,结果表明,3 个因素对白藜芦醇提取量的影响主次顺序为提取温度>β-环糊精质量浓度>处理时间;白藜芦醇的最佳提取条件为β-环糊精质量浓度28 g/L、提取温度50 ℃、处理时间68 min,在此条件下,白藜芦醇提取量为152.2 μg/g。

Abstract: The effects of β-cyclodextrin, 50% methanol and water on the recoveries of phenolic compounds and resveratrol from grape vine leaves were evaluated. The interaction between β-cyclodextrin and resveratrol was analyzed using molecular docking method. The results indicated that the highest total phenolic content was obtained by using 50% methanol, while β-cyclodextrin resulted in the highest yield of resveratrol. The hydrophobic cavity of β-cyclodextrin could accommodate the resveratrol molecule, and hydrogen bindings between β-cyclodextrin and resveratrol led to the formation of stable complexes. By applying one-variable-at-a-time approach and response surface methodology, the β-cyclodextrin-assisted extraction process of resveratrol from grape vine leaves was optimized. Temperature was the most significant factor affecting the yield of resveratrol, followed by β-cyclodextrin concentration and treatment time. The optimal conditions obtained were as follows: β-cyclodextrin concentration, 28 g/L; temperature, 50 ℃; and extraction duration, 68 min, under which a resveratrol yield of 152.2 μg/g was achieved.
