以芦丁为标准样品,用紫外分光光度法测定南天竹叶总黄酮含量,并与可见分光光度法进行比较.结果表明,紫外分光光度法较可见分光光度法准确、简便和快速,是测定南天竹叶总黄酮含量较为理想的方法. Rutin was used as a standard sample and the content of total flavonoids in Nantiandi bamboo was determined by UV spectrophotometry and compared with visible spectrophotometry.The results showed that UV spectrophotometry was more accurate, simple and rapid than visible spectrophotometry, Bamboo leaf flavonoids content is the ideal method.
