Abstract:
Medicinal plants are playing an imperative role in the therapy for treating various chronic ailments including
arthritis. The present study was focused on finding in vitro and in vivo anti-arthritic potential of P. braunii roots. In vitro protein denaturation, membrane stabilization and anti-trypsinase assays were carried out to demonstrate anti-arthritic activity of the extracts. Furthermore, the extracts exerting promising in vitro anti-arthritic potential were tested orally at 150, 300 and 600mg/kg/day against formaldehyde induced arthritis in Wistar rats. The methanolic, aqueous and ethyl acetate extracts of the plant revealed noteworthy in vitro anti-arthritic activities while mitigating formaldehyde induced paw edema in dose dependent manner. Methanolic and aqueous extracts showed the highest inhibition (p<0.05) of paw edema, arthritic indices, reduced elevated level of platelets and leukocytes while increasing hemoglobin and body weight of arthritic rats. Anti-arthritic activity of the plant extracts may be due to inhibition of protein denaturation and lysosomal membrane stabilization. The plant exhibited good anti-arthritic potential.
