Abstract
Ivy leaves (Hedera helix) is a traditional plant used for common cold, cough, and bronchial disorders and can be used for rheumatoid arthritis (RA) as an attempt in alternative medicine. RA is a chronic autoimmune disease characterized by its increasing frequency and adverse consequences. There is an urgent need for a long-term therapy that has favorable biological effects and is less expensive than the already authorized synthetic medicines. This study aimed to determine the anti-arthritic potentials of Hedera helix with determination of the bioactive fraction and discovery of its second-generation metabolites by means of LC/MS. The total ivy ethanolic extract (TIE-E), saponins fraction (Sap-F) and flavonoids fraction (Flav-F) were investigated for their in-vitro anti-arthritic effects and in-vivo by Adjuvant-induced arthritis (AIA) using Complete Freund's Adjuvant (0.1mL, CFA) intradermal relative to the usual dose of ibuprofen (5mg/kg). We examined the physical alterations, rheumatoid biomarkers, cytokines that cause and inhibit inflammation, markers of oxidative stress, hyaluronidase and β-glucuronidase enzyme activity. Each paw's histopathology was also evaluated. The chemical profiles of TIE-E were studied using LC/MS in both positive and negative ionization modes. TIE-E (200mg/kg) and Flav-F (100mg/kg) significantly (P< 0.05) lowered the edema of the paws, serum immunological indicators, inflammatory cytokines, degenerative enzymes, and indicators of reactive oxygen species with increasing in the anti-inflammatory cytokines. Our findings suggest that extracts of ivy leaves might be used effectively to treat rheumatoid arthritis, where its flavonoid content is responsible for that, and it is able to repress biochemical, oxidative, and pathological changes associated with (AIA) Adjuvant-induced arthritis.
