摘要: 以引种栽培的新食物资源--卡亚为原料,对其多酚类进行定性定量分析,并以总多酚得率为目标,进行提取工艺优化研究。结果表明,卡亚含有鞣质、多酚和黄酮类物质,100g卡亚鲜叶含单宁0.49g、黄酮类1.29g以及酚类2.57g。通过单因素及正交试验优化提取工艺,确定卡亚酚类物质提取的最佳条件为料液比1:15(g/mL)、温度60℃、提取时间3h、超声辅助提取时间20min,100g卡亚鲜样优化提取多酚得率最高为408mg。

Abstract: A new food resource, chaya was qualitatively and quantitatively analyzed for its polyphenol components. The extraction of polyphenols from the food resource was optimized based on total polyphenol extraction rate. The results indicated that chaya contained tannins, polyphenols and flavonoids, which were 0.49, 2.57 g and 1.29 g in 100 g of fresh chaya leaves, respectively. The optimal extraction conditions for chaya polyphenols that were determined by single-factor and orthogonal array design were: material/liquid ratio of 1:15, extraction temperature of 60 ℃, extraction time of 3 h and ultrasonic treatment time 20 min. Under the condtions, 408 mg of polyphenols was extracted from 100 g of fresh chaya.

Key words: new food resources, chaya, polyphenol, extraction process
