ObjectiveThis research aimed to study the antioxidant activity of polyphenols of Chinese Dates from different counties of north of shaanxi province and compared in four antioxidant systems separately. Methods The antioxidant activities of each polyphenols of Chinese Dates were tested in vitro by scavenging different free radicals and H2O2 tests: ①tested the capability of scavenging·OH; ② tested the capability of scavenging O-2 ·; ③ tested the capability of scavenging DPPH·; ④tested the capability of scavenging H 2 O 2 . ResultsAll the polyphenols of Chinese Dates from different counties of north of shaanxi had certain antioxidant capacity,but different polyphenols from different parts had different capacity in clearing away free radicals or H2O2 . ConclusionsPolyphenols of Chinese Dates from north of Shaanxi has stong antioxidant capacity and it is a good natural antioxidant.
