Hepatoprotective and Anti-inflammatory Activities of Algerian Capparis spinosa. L

ABSTRACT

The aim of this study was to evaluate anti-inflammatory and hepatoprotective effects of methanolic extracts from fruits and leaves of Capparis spinosa. For hepatoprotective activity, liver injury was induced in male Wistar mice by administration of CCl4 (1 ml / kg of CCl4 30% in olive oil,), while C. spinosa leaf extract (CSLE) and fruit extract (CSFE) were administered orally to the experimental animals. Haematoxylin and Eosin based histology was performed to evaluate the histological changes in the liver. In vitro anti-inflammatory activity was evaluated using albumin denaturation assay and membrane stabilization inhibitory activity at different concentrations. The methanol extracts showing effective in vitro anti-inflammatory activity were also tested for in vivo anti-inflammatory activity by carrageenan-induced paw edema in mice model. At a dose of 400 mg / kg, both extracts showed significant reduction of edema in the early and late phases of acute inflammation with a maximal effect at 6 hours after induction of the inflammation. Also and at the concentration of 400 µg / ml, the CSFE and CSLE exhibited significant protection of erythrocyte membrane against the lysis induced by heat (35.4% and 28.4%, respectively) and induced hypotonicity (58.9% and 72.8%, respectively). They also showed a significant protective effect, with a maximum percent of inhibition of the denaturation of albumin of 61.78% and 61.12%, respectively. Moreover, both extracts showed significant hepatoprotective activity that was evident by enzymatic examination and histopathological study. These findings proved that CSFE and CSLE have an anti-inflammatory and hepatoprotective activities, although slightly better for the leaf extract.
