| 摘 要： | 采用单因素及正交试验设计对金花茶叶中总黄酮提取工艺进行了研究，并以芦丁为对照品，采用分光光度法对金花茶中总黄酮动态变化规律进行了研究。结果表明：金花茶叶中总黄酮最佳提取条件为乙醇体积分数70%、料液比1:50(g/ml)、提取时间2.0h、温度70℃。1～10 月份金花茶叶中总黄酮含量呈波动性上升趋势，10月份达到最高。

| Abstract: | Based on the results of single factor, orthogonal test design was adopted to optimize the extraction technology of total flavonoids in Camellia nitidssima leaves. With rutin as reference material, the dynamic change law of content of total flavonoids in Camellia nitidssima leave was analyzed using spectrophotometry. The results showed that the optimal extraction conditions are: using 70% ethanol as extractant, ratio of material to solution 1:50 (W/V), extraction time 2.0 h, extraction temperature 70 ℃. The content of total flavonoids in Camellia nitidssima increases fluctuatingly from January to October, reaching the highest at October. |
