Abstract: Polyphenols, flavonoids and anthocyanin content of various green tea extracts were investagted. Ferrous ion chelating, 2,2-diphenyl-1-picrylhydrazyl radical scavenging, ferric reducing power of green tea extracts were performed. The results showed that green tea Huang shanmaofeng to the highest total phenol content. Flavonoids contents had no significant difference. Anthocyanin content of decreasing order is Xinyangmaojian, Huangshanmaofeng and Yingzhouyafeng. Ferrous ion chelating capacity order was Huangshanmaofeng, Xinyangmaojian and Yingzhouyafeng. In dilution 2, the ferrous ion chelating ability of Huangshanmaofeng was 1.32 fold and 1.38 fold higher than that of Xinyangmaojian and Yingzhouyafeng respectively. On 0.25-1mgDW/mL concentrations, the DPPH scavenging capacity of Huangshanmaofeng was significantly higher than that of Xinyangmaojian and Yingzhouyafeng. However, no significant difference was observed in DPPH scavenging capacity between Xinyangmaojian and Yingzhoumaofeng. In dilution 2, iron reducing power of Huangshanmaofeng was 1.35 fold and 1.4 fold higher than that of Xinyangmaojian and Yingzhouyafeng respectively.
