Keywords


In order to understand the synergetic effect between loquat leaves flavonoid and osmanthus fragranst leaves flavonoid, synergetic effect and optimal formulation of compound antioxidant were determined with the response surface method (RSM). The results showed that, the component ratio of optimal compound antioxidant was loquat leaves flavonoid 100.00μg·ml-1 and osmanthus fragranst leaves flavonoid 47.52μg·ml-1, the DPPH scavenging rate of the system was 46.88% under the conditions. Compound antioxidant of loquat leaves flavonoid and osmanthus fragranst leaves flavonoid had antagonistic action.
