The total phenolic and flavonoid contents were determined using the Folin-Ciocalteu and aluminium chloride methods. Antioxidant and anti-inflammatory activities were evaluated using the ABTS assay and protein denaturation, LPS-induced RAW264.7 cells, respectively. The highest total phenolic (5.73 ± 0.06 mg GAE/g dry extract) and flavonoid (5.25 ± 01.6 mg QE/g dry extract) contents were found in C. virgatum, and it also shows good antioxidant activity with an IC value of 258.66 µg/mL. The protein denaturation assay and NO production inhibition assay of C. virgatum showed the lowest IC value (65.39 µg/mL) and lower NO level. Analysis of secondary metabolites using HR-LCMS reveals the presence of 12 phytoconstituents in C. virgatum extract. From these results, it is evident that C. virgatum can contribute to the development of antioxidant and anti-inflammatory agents.
