Evaluation of Anti-Arthritic Potential of Partitioned Extracts of Bougainvillea X Buttiana (Var. Rose) Holttum and Standl

Abstract

Objective: Bougainvillea is a natural source with potential for clinical use, and this plant is routinely employed in traditional Medicine in Mexico. This study planned to evaluate the effect of ethanolic extract partitioned of Bougainvillea x buttiana on acute and chronic inflammation.Methods: The extract from Bougainvillea x buttiana partitioned originated two phases the aqueous (BxbREaq) and organic (BxbREop) phases were employed in anti-inflammatory activity. Acute inflammation was evaluated using the carrageenan model, whereas the chronic inflammation with anti-arthritic potential was explored with complete Freund´s adjuvant (CFA). Arthritis was caused by intradermal inoculation of CFA, and the extract was administered orally at different doses for 21 d. Paw oedema was determined at 7, 14 and 21 d, and serum from the mice were obtained to detect cytokine levels by ELISA and for biological assays.Results: Phytochemistry studies revealed that these extracts contain alkaloids, carbohydrates, fatty acids, and tannins. The results demonstrated that these extracts significantly inhibited mouse paw oedema for acute and chronic inflammation in a dose-dependent manner. Additionally, BxbREop extracts markedly inhibited the production of TNF-α, IL-1β, and IL-6 and remarkably increased IL-10 in serum from mice with control or arthritic groups.Conclusion: The combined results suggest that BxbREop extract shows a potent effect in mice against CFA-induced arthritis for its ability to inhibit paw oedema and arthritic symptoms.

“…These powders were utilized for further experimental purposes. Extracts were prepared by Soxhlet apparatus (ROTAMANTAL, REMI) [13] using solvents, namely, ethyl acetate and ethanol at 60-80°C for 24 h. [14] These extracts were consequently evaporated under reduced pressure at 45°C in a rotary evaporator (IKA RV 10).…”
