[Objective] To evaluate the antioxidant activity of total alkaloids in Abrus cantoniensis Hance stems. [Methods]The experiment of clearing super O_2~-·,clearing DPPH· and suppressing β-carotene-linoleic acid was conducted on Abrus cantoniensis Hance stems. [Results]The total alkaloids in Abrus cantoniensis Hance stems had strong antioxidant effect on β-carotene-linoleic acid oxidation system,and had the ability to scavenge super O_2~-· and DPPH· free radical. [Conclusions]Different in vitro antioxidant models showed that the total alkaloids in Abrus cantoniensis Hance stems had strong antioxidant activity.
