Abstract
Abstract Withania frutescens ( W. frutescens ) is a medicinal plant that is largely used in the Morrocan pharmacopeia for disease treatment. This work was conducted to investigate the chemical characterization, analgesic, anti-inflammatory, and healing activities of W. frutescens . The chemical characterization of W. frutescens extract was done using HPLC; the anti-inflammatory test was performed with doses 300, 400 and 450 mg/kg, and the healing activity was assessed using two creams (extract 5% and extract 10%). Phytochemical analysis revealed the presence of phenolic compounds. The results of the anti-inflammatory test were more pronounced when compared with the reference drug with a maximum inhibition percentage of 82.20% ± 8.69 obtained at the dose of 450 mg/kg. Local application of 10% plant cream induced 80.17% ± 7.89 of inflammation inhibition when compared with the indomethacin drug 92.33% ± 11.27. The studied plant extract showed a promising healing activity with the following percentage: 99.03% ± 0.76 (extract 10%), 98.61% ± 1.91 (extract 5%), and 57.43% ± 2.97 (control); meanwhile, the value reached to 100% ± 0.02 for the drug that was used as a reference within the first 2 weeks. The plant studied in this work would be a promising source for conceptualizing effective drugs against inflammatory diseases.
