Abstract:In this experiment, total flavonoids of Guangzao, Ephedra, Kam grass were extracted by ethanol as solvent and ultrasonic aided, spectrophotometry was used to determine the content of flavonoids and recovery rate. The results showed: Guangzao in C = 11.6 mg/g, RSD:0.89 % ; Ephedra C content = 37.3 mg/g, RSD: 0.97% ; Gallic C content = 15.4mg/g, RSD: 1.23%. Three samples of the recovery 94.1% - 96.35 %.
Keywords:Spectrophotometry  Guangzao  Ephedra  Kam grass  Flavonoids
