Abstract: Objective: To study the capacity of hesperidin, limonene and tea polyphenols on sequestering 1, 1 diphenyl-2-trinitrobenzene hydrazine (DPPH·) and hydroxyl free radical (·OH) . Methods: UV-Vis spectrum analysis method was used to determinate the three natural products on DPPH· and ·OH free radical scavenging. Results: The three natural products in the experimental concentration range have the capacity to remove the free radicals, the removal of effect increases with the concentration. The capacity of hesperidin (IC50=0.097, 0.011) is stronger than the limonene (IC50=0.00236, 0.0004), tea polyphenol (IC50=0.0144, 0.0009) on DPPH· and ·OH scavenging. Conclusion: The antioxidant capacity of hesperidin is stronger than tea polyphenol and limonene in vitro.
