Aerial parts of the plant Sida rhombifolia Linn. (Malvaceae) were extracted successively to produce various extracts. These extracts were screened for various parameters of anti-arthritic activity, such as adjuvant-induced arthritis, motor performance, mean distance travelled, and histopathological study. Results showed that the polar constituents (ethanol and aqueous extracts) of the plant S. rhombifolia were useful in the treatment of arthritis.
SUMMARYAerial parts of Sida rhombifolia Linn. (Malvaceae) were extracted successively using various solvents and screened for various parameters of antiarthritic activity such as adjuvant-induced arthritis, motor performance, and histopathological study. The ethanol and the aqueous extracts showed potent activity; further these extracts were fractionated by using column chromatography. The fraction ET1 isolated from ethanol extract showed the most potent antiarthritic activity.
The study was done to assess the in-vitro antibacterial potential of various extracts was studied and compared with ciprofloxacin as the standard and shows significant action against E. coli, B. substilis S. aureus, S. pyrogenes, P. aeruginosa, and S. typhi. Anti-fungal potential of the aqueous extract also studied using miconazole as standard and shows significant action against A. niger and C. albicans. Anthelmintic potential of the aqueous and ethanolic extracts was also studied on earthworms, Eudrillus eugeniae using albendazole as standard and shows moderate activity. In the present study in-vitro free radical scavenging activity of whole plant material performed. Various crude extracts of S. xanthocarpum was prepared by successive maceration process using various solvents such as; chloroform, petroleum ether (60-80o), acetone, ethanol and distilled water. Each one extract have been chosen to study the free radical inhibitory activity by DPPH radical scavenging method. The preliminary phytochemical screening of extracts showed that sterols, alkaloids, glycosides, tannins, saponins, phenolic compounds, carbohydrates and proteins were present in the plant. Petroleum ether, chloroform, acetone, ethanol and distilled water extracts showed 52.69, 46.15, 21.08, 52.72 and 44.35 % respectively compared to standard ascorbic acid. Acetone extract showed poor inhibition of DPPH radical compared to standard and other extracts also.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
