Title: Determination of the Total Flavonoids in Lonicera confusa DC
Abstract: [Objective] To detect the content of total flavonoids in flowers and leaves of Lonicera confusa(Lonicerae Flos);[Method] UV-Vis spectrophotometry was used to detect the total flavonoids contents in L.confuse leaves and flowers.With the total flavonoids rate as the index,conditions affecting the extraction rate of total flavonoids were preliminarily discussed.[Result] The optimal extraction condition for total flavonoids was as follows: 60 min extraction time,1∶30 solid-liquid ratio,and 70% ethanol concentration.The contents of total flavonoids in L.confuse flowers and leaves were 5.655% and 3.459%,respectively.[Conclusion] L.confuse flowers and leaves were relatively rich in total flavonoids,which had great utilization value for Caprifoliaceae resources in southern China.
