Title: Determination of the total flavonoids in FLOS LONICERAE in Hainan Province.
Abstract: [Objective] To detect the content of total flavonoids in flowers (FLOS LONICERAE) and leaves of Lonicera confusa. [Method] UV-Vis spectrophotometry was used to detect the total flavonoids contents in L. confusa leaves and flowers. With the extraction rate of total flavonoids 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. confusa flowers and leaves were 5.655% and 3.459%, respectively. [Conclusion] L. confusa flowers and leaves were relatively rich in total flavonoids, which had great utilization value for Caprifoliaceae resources in southern China.
