Evaluation of Acacia cyanophylla for their analgesic, anti-pyretic and anti-inflammatory potentials.

The present paper presents results of analgesic, antipyretic activity and anti-inflammatory potential of extract obtained from Acacia cyanophylla when tested at different doses. Analgesic potential of the crude methanolic extract tested by acetic acid assay was dose dependent and maximum activity of 61.60% was measured at 400 mg/kg. Analgesic activity by hot plate method revealed that maximum activity of 36.98% was noted when the mice were exposed to 90 minutes at higher dose of 400 mg/kg. Similar pattern for antipyretic activity was observed as noted for analgesic activity. Anti-inflammatory activity was dose and time dependent when evaluated by Carrageenan-induced paw edema and Xylene-induced ear edema model. Maximum anti-inflammatory activity (43.32%) was shown by crude methanolic extract of Acacia cyanophylla at 400mg/kg ^-1 after 5 hours on Carrageenan-induced paw edema model. Similarly, maximum (68.80%) anti-inflammatory activity was noted when accessed by Xylene-induced ear edema model at the dose of 200mg/kg after 60 minutes. No in vivo toxicity of the extracts up to the dose of 2000mg/kg was observed using albino mice.
