摘要：该文研究溶剂对核桃内种皮中不同形态酚酸类化合物的提取率,建立了适用于核桃内种皮中酚酸类化合物的提取方法。以新疆核桃为原料,比较不同比例的甲醇、乙醇溶液对核桃内种皮中可溶性游离态、可溶性酯化态和不溶性结合态酚酸的提取率。结果表明,50%(体积分数,下同)甲醇适合提取可溶性游离态绿原酸、没食子酸;50%(体积分数,下同)乙醇适合提取可溶性游离态丁香酸、香草酸;60%乙醇适合提取可溶性酯化态没食子酸;100%乙醇适合提取可溶性游离态原儿茶酸、不溶性结合态香草酸;80%甲醇和70%乙醇2种溶液对于上述以外的核桃内种皮3种不同形态的大多数酚酸具有较高的提取率。研究结果可为核桃内种皮中不同形态不同种类酚酸的提取开发利用提供参考。
The extraction efficiency of different forms of phenolic acids from walnut pellicle was studied,and a suitable extraction method for phenolic acids from walnut pellicle was established.The effects of different proportions of methanol and ethanol on the extraction of soluble free,esterified and insoluble bound phenolic acids from walnut pellicle were compared.The results showed that 50%methanol was suitable for extracting soluble free chlorogenic acid and gallic acid and 50%ethanol was suitable for extracting soluble free syringic acid and vanillic acid.Moreover,60%ethanol was suitable for extracting soluble esterified gallic acid and 100%ethanol was suitable for extracting soluble free protocatechuic acid and insoluble bound vanillic acid.Besides,80%methanol and 70%ethanol solution both had higher extraction rates for most of the three different forms of phenolic acids.The results could provide a reference for the extraction and utilization of different phenolic acids in walnut pellicle.
