Abstract

Background/aim: To determine the phenolic acid levels and DNA damage protection potential of Capparis spinosa L. seed extract and to investigate the effect of the extract on cognitive impairment and oxidative stress in an Alzheimer disease mice model. Materials and methods: Thirty BALB/c mice divided into 5 groups (control??, D-galactose, D-galactose + C. spinosa 50, D-galactose + C. spinosa 100, D-galactose + C. spinosa 200) were used. Mice were administered an injection of D-galactose (100 mg/kg, subcutaneous) and orally administered C. spinosa (50, 100, or 200 mg/kg) daily for 8 weeks. Results: Syringic acid was detected and the total amount was 204.629 μg/g. Addition of 0.05 mg/mL C. spinosa extract provided significant protection against the damage of DNA bands. C. spinosa attenuated D-galactose-induced learning dysfunctions in mice and significantly increased memory retention. Malondialdehyde (MDA) levels increased and superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) activities decreased in the D-galactose group. C. spinosa (200 mg/kg body weight) significantly decreased MDA level and increased SOD, GPx, and CAT activities. Conclusion: These results show that C. spinosa has the potential in ameliorating cognitive deficits induced by D-galactose in mice and the antioxidant activity may partially account for the improvement of learning and memory function.
