Abstract
The neuroprotective effect of flower and fruit parts of Capparis ovataDesf. var. palaestinaZoh. plant was investigated in H2O2-induced cytotoxicity in SH-SY5Y cells. The cells were treated with H2O2alone or pretreated with flower (COMFL) and fruit extract (COMFR) of C. ovatavar. palaestina. MTT, xCELLigence, and qualitative and quantitative determination of phytochemical constituents in the extracts by LC-MS/MS methods were employed. COMFL and COMFR had a neuroprotective effect and this effect was stronger when the presence of oxidative stress. The mass spectrums revealed the presence of flavonoids and phenolic acid derivatives in the extracts. According to quantitative analyses, the main compounds were myristoleic acid, apigenin, caffeic acid, caffeic acid-3-glucoside, and 5-cynapoil quinic acid in both COMFL and COMFR and rutin was found in COMFL. The extracts could inhibit H2O2induced neuronal cell death whichmight be beneficial for the pretreatment of oxidative stress in neurodegenerative diseases
