摘要
研究了银鹊树叶中总黄酮的提取方法,并用硼酸-柠檬酸比色法和硝酸铝比色法2种方法测定了银鹊树叶不同季节总黄酮的含量。硼酸-柠檬酸法测定银鹊树叶总黄酮含量为:新叶0.221%,老叶0.282%;硝酸铝法测定银鹊树叶总黄酮含量为:新叶0.350%,老叶0.414%。提出了测定非羰基黄酮类化合物的方法。
The extraction conditions of flavonoids in the leaves of Tapiscia sinensis were studied. The content of flavonoids in different seasons was determined by boric acid-citric acid colormetry and aluminum nitrate colormetry, the determining results of spring leaves and autumn leaves were compared.The determining method of non-carbonyl flavonoids has been put forward.
