Objectives: The aim of this study was to evaluate the analgesic and the anti-inflammatory activity of Opuntia microdasys at post flowering stage, F3 (OMF3) in rat and, in other hand, its antigenotoxic effects by the Allium cepa test. Methods: OMF3 extracts were screened for activity of analgesic and anti-inflammatory using, respectively, the acetic acid writhing test in mice and the carrageenan-induced paw oedema assay in rats. The antigenotoxic has been evaluated by A. cepa test. Key findings: OMF3 extracts showed a higher analgesic and anti-inflammatory activity at 100 mg/kg (72.03% and 70.11%) as determined by the tests of acetic acid-induced writhing and carrageenan-induced oedema, respectively. Furthermore, the OMF3 aqueous extracts have a preventive antimutagenic potential, at lower concentration (EC50 ≈ 60 μg/ml), against H2O2-mediated DNA damage in A. cepa root meristem cells with an efficient restoration of the mitotic index in comparison with controls. Conclusions: Based on this study, the flower of O. microdasys at post flowering stage may be use as an analgesic, anti-inflammatory and antimutagenic agents.

Abstract
Objectives: The aim of this study was to evaluate the analgesic and the anti-inflammatory activity of Opuntia microdasys at post flowering stage, F3 (OMF3) in rat and, in other hand, its antigenotoxic effects by the Allium cepa test. Methods: OMF3 extracts were screened for activity of analgesic and anti-inflammatory using, respectively, the acetic acid writhing test in mice and the carrageenan-induced paw oedema assay in rats. The antigenotoxic has been evaluated by A. cepa test. Key findings: OMF3 extracts showed a higher analgesic and anti-inflammatory activity at 100 mg/kg (72.03% and 70.11%) as determined by the tests of acetic acid-induced writhing and carrageenan-induced oedema, respectively. Furthermore, the OMF3 aqueous extracts have a preventive antimutagenic potential, at lower concentration (EC50 ≈ 60 μg/ml), against H2O2-mediated DNA damage in A. cepa root meristem cells with an efficient restoration of the mitotic index in comparison with controls. Conclusions: Based on this study, the flower of O. microdasys at post flowering stage may be use as an analgesic, anti-inflammatory and antimutagenic agents.File | Dimensione | Formato | |
