摘要: 花生蔓中含有丰富的黄酮类化合物,采用分光光度法,以芦丁为标准品,测定花生蔓中不同部位总黄酮含量。通过L9(34)正交试验设计,考察了提取条件与黄酮提取量的关系。结果表明,花生蔓中黄酮类物质的最佳提取工艺为:乙醇浓度60%,提取温度65℃,料液比1g:40ml,超声时间20min。

Abstract: Peanut vines are rich in flavonoids compounds. Flavonoids in peanut vines were determined by spectrometric metnod with rutin as a standard in this study. Flavonoids from peanut vines of various organs were prepared according to L9(34) orthogonal tests plan. The relationship between extracting conditions and yield of flavonoids extracted form peanut vines was investigated. The results showed that the optimum extracting conditions are: ethanol concentration 60%, temperature of extraction 65 ℃, solid-liquid ratio 1 g:40 ml and uitrasonic wave time 20 min
