ABSTRACT
Leaves, stems and their ashes of Prosopis cineraria and Hibiscus rosa-sinensis have been explored for their surface sorption abilities towards Methyl Orange Dye using simulated waters. Various physicochemical parameters such as pH, time of equilibration and sorbent concentrations are optimized for evoking the sorption potentialities of the plant materials for the maximum extraction of the Methyl Orange Dye from waters. The surface sorption nature is found to pH sensitive and % of removal is maximum near pH: 3. % removal of the Dye is more with ashes than respective bio-materials. Co-anions, in fivefold excess, are found to be interfering in the order: trivalent anion>divalent > monovalent while co-cations have shown relatively less interference on the extraction of the Dye at optimum conditions of extraction. The adoptability of the methodologies developed is tested with some real industrial effluents.
ABSTRACT
Prosopis cineraria (L.) Druce is a deep rooted, nitrogen fixing, multipurpose tree endemic to the hot deserts of India. Its synonym is Prosopis spicigera. It belongs to the family Leguminosae and subfamily Mimosoideae. In view of its medicinal importance, the present research was focused on the analgesic properties of roots of P. cineraria by in vitro approach in rats. The analgesic activity of root of Prosopis cineraria was studied using hot-plate method and tail-immersion method in rats. Doses of the ethanolic extract of 200mg/kg & 300mg/kg, orally were selected for analgesic activity. The extract at all the doses used and the Diclofenac sodium significantly inhibited both the analgesic activity for hot plate and tail immersion method. The present study demonstrates the potential analgesic effect of ethanolic extracts of Prosopis cineraria roots. The dose of 200mg/kg b.w is very effective than 300mg/kg b.w in both above pharmacological models.
