This study aimed to evaluate the potential of aqueous extract from Mitracarpus frigidus aerial parts (MFAq) in the treatment of inflammation and oxidative stress, as well as to characterize its chemical constituents. Total phenolic and flavonoid contents were determined, and phytoconstituents were detected by ultra-fast liquid chromatography/quadrupole-time-of-flight tandem mass spectrometry (UFLC-QTOF-MS). The antioxidant activity was evaluated by DPPH, TAC and β-carotene/linoleic acid assays. In-vitro anti-inflammatory activity, cell viability and cell cycle were performed in J774A.1 cell line. In-vivo anti-inflammatory activity was investigated by two ear oedema assays (croton oil and phenol). Chlorogenic acid, clarinoside, quercetin-hexosylpentoside, rutin, kaempferol-3-O-rutinoside, kaempferol-rhamnosylhexoside, quercetin-pentosylrhamnosylhexoside, harounoside, 2-azaanthraquinone and sucrose were identified by UFLC-QTOF-MS. MFAq showed antioxidant activity, which was positively correlated to the content of phenolic compounds. MFAq significantly inhibited the production of nitric oxide, did not decrease viability in MTT assay (all concentrations) and showed no changes in membrane permeability and cell cycle of J774A.1 cell line. Furthermore, MFAq showed a reduction in ear oedema in all tested doses. MFAq was effective in some antioxidant and inflammatory parameters, in the experimental conditions that were used in the study. This is the first report of chemical composition and bioactivities from this extract.
