Objective:To investigate the antioxidant and anti-inflammatory activity of orally administered methanolic leaf extract of Dalbergia paniculala(D.paniculata) in Carrageenan induced inflammation in rats.Methods:In vitro antioxidant activity was evaluated for superoxide radical, Hydroxyl radical and DPPH radical scavenging activity.Three doses 200 mg/kg,400 mg/kg and 800 mg/kg of D.paniculala were tested for anti-inflammatory activity in Carrageenan induced rat paw edema model and paw thickness was measured every one hour up to 6 h. Results:The melhanolic leaf extract of D.paniculala produced dose dependent inhibition of Superoxide radical,Hydroxyl radical and OPPH radicals.In Carrageenan induced inflammation model,all three doses produced significant percentage inhibition of rat paw edema and 800 mg/kg dose produced maximum percent inhibition of rat paw edema(47.83%) at 3h compared to control group.Conclusions:In the present study we found that methanolic leaf extract of D.paniculata showed good in vitro antioxidant activity and in vivo anti-inflammatory activity in rats.
Objective: To investigate the antioxidant and anti-inflammatory activity of orally administered methanolic leaf extract of Dalbergia paniculala (D. paniculata) in Carrageenan induced inflammation in rats. Methods: In vitro antioxidant activity was evaluated as superoxide radical, Hydroxyl radical and DPPH radical scavenging activity.Three doses 200 mg / kg, 400 mg / kg and 800 mg / kg of D. paniculala were tested for anti-inflammatory activity in Carrageenan induced rat paw edema model and paw thickness was measured every one hour up to 6 h. Results : The melhanolic leaf extract of D. paniculala produced dose dependent inhibition of Superoxide radical, Hydroxyl radical and OPPH radicals. In Carrageenan induced inflammation model, all three doses produced significant percentage inhibition of rat paedema and 800 mg / kg dose produced maximum percent inhibition of rat paw edema (47.83%) at 3h compared to control group. Conclusions: In the present study we found that methanolic leaf extract of D. paniculata sho wed good in vitro antioxidant activity and in vivo anti-inflammatory activity in rats.
