| Abstract: | Ultrasonic method is applied for extracting flavones in the black teas. The content of the flavones is determined by absorption spectroscopy. The recovery is 97.5% - 103.5% and the coefficient of variation is less than 0.068%. Anti oxidation effect of the black teas is studied by flow injection chemiluminescence. The results show that the black teas is abundant in the flavones compounds and has a strong anti oxidative effect. |
