Objective： To purify polyphenols from Sabina vulgaris and to investigate its antioxidant properties. Methods： Polyphenols were purified from Sabina vulgaris Antoine with macroporous resin HPD-700, and the quantity of polyphenols was determined by    Folin-Ciocalteu colorimetry. The antioxidant properties of polyphenols were evaluated by total antioxidant capacity (T-AOC) and its activeties of scavenging DPPH (1,1diphenyl-2-picry-hydrazyl) radicals, superoxide anion (O2·-), hydroxyl free radicals (OH·) and ferric     reducing antioxidant power (FRAP). Results： After purification, the purity of polyphenols increased from 0.53‰ to 9.95‰.The antioxidant properties study showed that its inhibition rate of scavenging DPPH radicals and FRAP was 151.83 U/ml and 204.59 U/ml. Its scavenging capacity for superoxide anion (O2·-) and hydroxyl free radicals (OH·) was 151.83 U/ml and 204.59 U/ml. The total antioxidant capacity  was 72.68 U/ml. Conclusion： Polyphenols from Sabina vulgaris Antoine have high antioxidant properties, suggesting that it worth further study of its pharmacological effects.
