Abstract:
Objective:To establish the determination method for total flavonoids in Cyperus rotundus and investigate the total fla-vonoids content in Cyperus rotundus from different habitats. Methods:Total flavonoids in Cyperus rotundus from different habitats were detected by ultraviolet spectrophotometry with rutin as the standard substance. Results:The absorbance of rutin had a good linear cor-relation with the concentration within the range of 0.064 3-0.642 6 mg·ml-1(r =0.999 1). The average recovery was 99.74%(RSD=2. 16%,n=6). The order of total flavonoids content in Cyperus rotundus from different habitats was Henan province >Sichuan province> Guangdong province >Anhui province > Halnan province >Shandong province. Conclusion:The method is easy and ac-curate, which can be applied in the quality control of Cyperus rotundus. The total flavonoids content in Cyperus rotundus from Henan province is the highest.
