| Abstract: | Objective]The aim was to establish a simple and quick method to determine total flavonoids content in Limonium aureum(L.)Hill.to provide scientific evidence for the quality control and development of Limonium aureum(L.)Hill.Methods]With quercetin as the reference substance,UV Spectrophotometry was used and the detection wavelength was 370 nm.Results]The linear relationship was good(r=0.999 6)in the range of 2.5-12.5 μg/ml,the average recovery rate of total flavonoids was 99.46 % and the content of total flavonoids in the samples was 1.63 %.Conclusion]UV Spectrophotometry is a suitable method for detection of total flavonoids content in Limonium aureum(L.)Hill.for its simple and quick characteristics,and it will provide the scientific evidence for the quality control and development of Limonium aureum(L.)Hill. |
