Abstract: Pomelo peel contains lots of flavonoids, these pomelo peel flavonoids exhibit immune enhancement, antioxidant, anti-inflammatory activities. Thus, the extraction methods of total flavonoids in pomelo peel were optimized in this study. Firstly, extraction rate of total flavonoids was taken as the evaluation index, and ethanol concentration, solid-liquid ratio and extraction time was determined through single factor screening. Then, the optimum formulation of flavonoids extraction was determined by orthogonal design. In the optimum extraction method, the ethanol concentration was 30%(v/v), the solid-liquid ratio was 1∶25(g∶mL), and the ultrasonic time was 90 min. Under optimal method, extraction rate of total flavonoids could reach 6.5%(m/m)。

Key words: pomelo peel, total flavonoids, extraction method, single factor screening, orthogonal screening
