Abstract
Medicinal plants
are potential sources of natural products that play an important role in
preventing different human diseases; the aim of the present study is to
evaluate the anti-inflammatory and the anti-arthritic effect of Peganum harmala
L. The anti-inflammatory effects were evaluated in vitro by bovine serum
albumin (BSA) denaturation inhibition test and in vivo using xylène-induced ear
edema model. Arthritis was induced in rats by intradermal immunization with
type II collagen emulsified in Freund’s Adjuvant, then arthritic rats were
treated with P. harmala hydromethanolic extract (PhHm) for 21 days and for 40
days for preventive and curative study, respectively, using two doses (50 and
100 mg/kg/Day). Results showed that PhHm extract significantly inhibited the
BSA denaturation. It had also a good anti-inflammatory effect in xylene-induced
ear edema model. P. harmala extract significantly inhibited arthritic
development. Treatment with the plant extract also nearly normalized counts of
platelets and total leukocytes. In conclusion, the current study demonstrated
that the hydromethanolic extract of P. harmala plays an effective role in the
anti-inflammatory effect and in both prevention and curative treatment of
collagen-induced arthritis.
