摘要: 本研究以牡丹根、茎、叶、花为原料,用乙醇作为浸提剂,对牡丹多酚提取沉淀时铝用量及pH值进行了研究。以正交试验研究了多酚沉淀转溶的工艺参数,对牡丹根、茎、叶、花中多酚含量进行了分析。结果表明,AlCl3法沉淀牡丹多酚的条件为:0.1mol/LAlCl3溶液用量2.5ml,pH5.3。牡丹多酚沉淀的最佳条件为:硫酸浓度1mol/L,料酸比1:1(V/V),温度55℃,时间5min。牡丹各部位多酚含量从高到低分别为:根、叶、茎、花。

Abstract: In this study,root,stem,leaf and flower of penony were used to extract polyphenol with ethanol.The 0.1 mol/L aluminium chloride amount and pH value for precipitating polyphenol in ethanol solution were explored,and the dissolution conditions of the polyphenol precipitate were optimized by using orthogonal test.The contents of polyphenol in root,stem,leaf and flower of penony were determined.Results showed that precipitation conditions of polyphenol in ethanol solution are as follows:0.1 mol/L aluminium chloride amount 2.5 ml and pH 5.3,and the dissolution conditions of the polyphenol precipitate are as follows:sulfuric acid concentration 1 mol/L,ratio of polyphenol precipitate to sulfuric acid(V/V),temperature 55 ℃ and time 5 min.The polyphenol content decreases from root,leaf,stem to flower.
