Abstract
Pain and inflammation are major health issues worldwide, leading to negative consequences. Despite several drugs being available to manage these conditions, their effectiveness can be limited by cost, adverse reactions, and potential tolerance and dependence with long-term use. Euphorbia characias traditionally used in folk medicine for its diverse biological activities - including antiproliferative, antimicrobial, and anti-inflammatory effects - has not been extensively studied in vivo for its analgesic and anti-inflammatory properties. In this study, the antinociceptive and anti-inflammatory properties of the water and ethanolic extracts of E. characias flowers (ECAEFl and ECEEFl) were evaluated using various models. Both extracts significantly reduced paw licking time in a formalin-induced paw licking model, with ECAEFl specifically targeting and ECEEFl affecting both the neurogenic and inflammatory phases. Additionally, in the carrageenan-induced cell migration model, both extracts showed a significant decrease in leukocyte migration, protein extravasation and nitric oxide levels, further demostrating their anti-inflammatory activity. High-Resolution HPLC-ESI-QTOF-MS-MS and HPLC-PDA analysis characterized the chemical composition of the extracts, identifying a significant presence of phenolic compounds, particularly quercetin and its derivatives, which likely contribute to the observed biological activities. These findings highlight the potential of E. characias extracts as natural sources of compounds with antinociceptive and anti-inflammatory properties. Further investigations are needed to elucidate the underlying mechanisms and explore their therapeutic potential in pain and inflammation-related disorders.File | Dimensione | Formato | |
