Evaluation of anti-inflammatory and analgesic activities of aqueous methanolic extract of Ranunculus muricatus in albino mice..
Pak J Pharm Sci Jan ;33(3):1121-6.

Ranunculus muricatus (Ranunculaceae) is commonly used by inhabitants of Pakistan for the treatment of gout and rheumatism, both of which are inflammatory disorders. The present study attempts to evaluate the anti-inflammatory and analgesic activities of aqueous methanolic extract of R. muricatus in mice. The plant extract at doses of 50, 100 and 150 mg/kg was tested for anti-inflammatory activity against carrageenan and egg albumin induced paw edema in mice and analgesic activity was appraised against acetic acid induced writhing and formalin induced paw licking in mice models. The results designate that extract at the highest dose of 150 mg/kg significantly (p<0.001) and dose dependently inhibited carrageenan induced and egg albumin induced paw edema. Similarly, extract at the same dose of 150 mg/kg showed potent and dose dependent (p<0.001) suppression of formalin induced paw licking and abdominal constrictions / stretching of hind limbs induced by acetic acid. The anti-inflammatory and analgesic activity of plant extract was comparable to standard drug ibuprofen in all models. This study thus supports the use of R. muricatus in traditional medicine for conditions associated with inflammation and analgesia which might be attributed to its previously proven high alkaloid, flavonoids, phenol, tannins content and free radical scavenging activity.
