Abstract: The total contents and components of flavonoids in 9 different citrus varieties and their DPPH radical scavenging activities and reducing powers were studied in this paper.The results showed that there were significant differences in total contents and components of flavonoids almost among all citrus varieties(P<0.05);The content of total flavonoids in NanFeng Miju was 9.68 mg/g,which was highest among all citrus varieties,while the content of total flavonoids in FuJian Migan was 5.28mg/g,which was the lowest;The content of naringin in FuJian Migan was high,while Jiangxi Liucheng,Jiangxi Qicheng,Nanfang Miju and Jiangxi Migan have a high content of hesperidin.There was no linear correlation between the contents of total flavonoids and their DPPH radical scavenging activities and reducing powers,that is,the antioxidant activity of the variety in which the content of total flavonoids was highest wasn't always strongest.The study can offer beneficial reference for establishing fingerprint of flavonoids in different citrus varieties in south China,as well as for the comprehensive utilization of citrus peel.
