| 摘 要： | 研究了槲树叶中黄酮类化合物的提取及其稳定性。结果显示:槲树叶中黄酮类化合物含量平均为2.4057%。温度在30～80℃时黄酮类化合物含量基本不变;加入偏重亚硫酸钠、亚硫酸氢钠、EDTA和吐温-80等稳定剂使槲树叶中黄酮类化合物含量保持稳定;pH值为4～7的条件下,样液中黄酮类化合物都能稳定存在;碳水化合物及金属离子对黄酮类化合物有较大影响。

| Abstract: | The research was carried on flavonoids extraction and stability of quercus dentata thunb.The results showed that: the content of flavonoids in the quercus dentata thunb is at an average level of 2.4057%.Flavonoids content is essentially the same under the temperature at 30℃ to 80℃.Sodium pyrosulfite,sodium bisulfite,EDTA and tween-80 can help flavonoids in the quercus dentata thunb stable.The pH value of 4 to 7 also can favorite the flavonoids stable;Carbohydrates and metal ions have a greater impact on flavonoids content. |
