    Abstract:

    Objectives: Galphimia glauca Cav (Gg) is an evergreen medicinal herb found growing in Indian subcontinent and more in the Deccan plateau regions of south India. The objective of the current work is to isolate, characterize and explore the muscle relaxant activity of the novel isolated phytomolecule (BS-4) from G. glauca stems using in vivo models. Methods: The obtained bio-active fraction (methanol fraction) of the G. glauca stem methanol extract (GgSME) was subjected to column chromatography and Preparative thin layer chromatography (TLC) to isolate the bioactive phytomolecule. The novel isolated bioactive phytomolecule was coded as “BS-4”, it is then characterized by Rf value, melting point, IR spectra, HPLC, Mass spectra, 1H-NMR spectrum and 13C NMR spectrum and evaluated for muscle relaxant activity by administering BS-4 in Swiss albino mice in one day to animal models like Rota rod test and Grip strengthening test. Results: The LD50 of BS-4 was > 2000 mg/kg. The mice were treated with BS-4 at 12.5, 25 and 50mg/kg doses. The BS-4 showed dose dependent significant (P ≤ 0.001) effects on muscle relaxant activity in Rota rod test and Grip strengthening test in mice (P ≤ 0.001). Conclusion: The current study results conclude that the isolated novel phytomolecule BS-4 has significant muscle relaxant effects.
