There is currently increased interest in the identification of antioxidant compounds that are pharmacologically potent and have low or no side effects. Plants produce significant amounts of antioxidants to prevent the oxidative stress caused by photons and oxygen, therefore they represent a potential source of new compounds with antioxidant activity. FARFARE FLOS has been frequently used on the respiratory system including bronchitis, phthisis. In this study, the antioxidant activity of extract from FF was studied in vitro methods by measuring the antioxidant activity by TEAC, measuring the scavenging effects on reactive oxygen species (ROS) [superoxide anion, hydroxyl radical] and on reactive nitrogen species (RNS) [nitric oxide and peroxynitrite] as well as measuring the inhibitory effect on Cu2+-induced human LDL oxidation. The FF extracts were found to have a potent scavenging activity, as well as an inhibitory effect on LDL oxidation. And this study was designed to evaluate whether FFEA may ameliorate oxidative stress and inflammatory status through the antioxidative mechanism in LPS-stimulated RAW 264.7 murine macrophage cell line. Treatment of RAW 264.7 cells with FFEA significantly reduced LPS-stimulated inflammatory response in a dose-dependent manner. In conclusion, the FF extracts have anti-oxidative and anti-inflammatory effects in vitro system, which can be used for developing pharmaceutical drug against oxidative stress and atherosclerosis.
