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 activities of scavenging DPPH (1,1 diphenyl-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 0.053% to 0.995%.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.
CONCLUSIONS
Polyphenols from Sabina vulgaris Antoine have high antioxidant properties, suggesting that it worth further study of its pharmacological effects.
