Abstract: The ultrasonic method was used for extracting flavonoids of Nanguo Pear and the flavonoids were determined by spectrophotometry, the recovery is 92.0%~105.0% and the coefficient of variation is 0.14%. The antioxidation effect of Nanguo Pea was studied by the flow-injection chemiluminescence. The results show that Nanguo Pear has antioxidative effect.

Key words: Nanguo Pear, spectrophotometry, flow-injection chemiluminescence method, antioxidative effect
