Abstrakt: Jeevaneeya rasayana is an ayurvedic polyherbal formulation, with antirheumatic potential. The present study investigates the therapeutic efficacy of isolated total alkaloid fraction of Jeevaneeya Rasayana (AJR) in treating rheumatoid arthritis in a rat model of Adjuvant-induced arthritis (AIA). Paw swelling, inflammatory mediators such as cyclooxygenase-2 (COX-2), matrix metalloproteinase-9 (MMP-9), level of prostaglandin E2 (PGE2), expression of cytokines and serum nitric oxide (NO) level were analyzed in experimental rats after an experimental period of 21 days. Arthritic induction significantly increased paw edema, and up regulated the inflammatory mediators and cytokines. Administration of AJR significantly reversed the paw edema, reduced the level of PGE2, serum NO and decreased the COX-2 activity in the paw tissue. AJR treatment also downregulated mRNA expression of pro-inflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and MMP-9 in paw tissue. HPTLC analysis revealed the presence of 5 different alkaloid compounds in AJR. These findings suggest that the AJR have the therapeutic potential against adjuvant-induced arthritis.
