摘要: The antioxidant activity of a methanolic extract Ocimum basilicum L. (sweet basil) was examined using different in vitro assay model systems. crude fractionated on Sephadex LH-20 column, and six fractions were identified. DPPH scavenging system the oxidation soy phosphotidylcholin liposome used to evaluate each fraction. Fraction IV showed strongest followed by V VI. Phenolic compounds responsible for antioxidative characterized atmospheric pressure chemical ionization liquid chromatography-mass spectrometry. major compound fraction confirmed as rosmarinic acid (1)H NMR characteristic fragmentations mass spectrum. Moreover, native examined. results that one can capture 1.52 radicals, furthermore, existence synergistic effect between alpha-tocopherol revealed.
