Sesuvium sesuvioides (Fenzl) Verdc is traditionally used in the treatment of inflammatory diseases such as arthritis and gout The aim of present study was to assess the possible anti-inflammatory, analgesic and antipyretic potential of the methanol extract of Sesuvium sesuvioides (SsCr) to prove scientifically its folklore use in the inflammatory diseases and to screen its total antioxidant capacity by multiple methods and phytocompounds by GC–MS. The preliminary phytochemical studies showed the presence of phenols, flavonoids, glycosides, coumarin, terpenoids, saponins, fats and carbohydrates in crude extract. The total phenolic contents (27.31 ± 0.28 mg GAE/g) and total flavonoids (3.58 ± 0.12 mgRE/g) values were observed. The antioxidant capacity of SsCr showed significant DPPH, ABTS, CUPRAC, FRAP, PBD and metal chelating results. GC–MS analysis displayed the phytoconstituents with anti-inflammatory potentials such as 2-methoxy-4-vinylphenol, vanillin, umbelliferone, methyl ferulate, palmitoleic acid, methyl palmitate and phytol. SsCr presented noteworthy HRBC membrane stability with maximum inhibition of cell hemolysis (47.79%). In carrageenan-induced hind paw edema assay result showed dose-dependent anti-inflammatory action. SsCr presented significant (p < 0.05) analgesic activity in hot-plate and tail flicking tests similarly it also showed the noteworthy inhibition in pain latency against formalin induced analgesia at 1st and 2nd phases. SsCr reduced the acetic acid-induced writhes at different doses (250, 500 and 750 mg). Results of antipyretic activity of SsCr extract were significant at 500 and 750 mg. The results of in vitro and in vivo experimental studies verified the anti-inflammatory, analgesic and antipyretic potential of Sesuvium sesuvioides and supported the folklore uses of this plant.
