Abstract:
OBJECTIVE:To investigate the eliminating ability of catechin to eliminate O2-* and *OH.
METHODS:The ability of catechin to clear away O2-* and *OH was respectively measured by faintness chemiluminescence and spin trapping assay.
RESULTS:IC50 that catechin eliminated O2-* and *OH was 6.16, 0.59 g/mL respectively, and the eliminating ability of catechin was much stronger than that of the extract from liquorice, rosemary, grape pip, giant knotweed and ginkgo leaf.
CONCLUSION:Compared with several important natural plants of antioxidants, the eliminating ability of cathechin is the best.
