Determination of Flavonoids and the Antioxidation Effect in C.pinnatifida Bunge

Abstract

Abstract: The ultrasonic method was used for extracting flavonoids of C.pinnatifida Bunge and the flavonoids were determinedby spectrophotometry, the recovery is 96%～105% and the coefficient of variation is 0.14%. The antioxidation effect of C. pinnatifida Bunge was studied by the flow-injection chemiluminescence. The results show that C.pinnatifida Bunge has the strength antioxidative effect, and the antioxidative effect increased with increasing concentration .

Key words: C.pinnatifida Bunge, flavonoids, spectrophotometry, flow-injection chemiluminescence method, antioxidativee ffect
