Raphanus raphanistrum L. (wild radish), a member of the Brassicaceae family, is an edible herb widely utilized in traditional medicine for the treatment of various ailments. This study aimed to evaluate the chemical composition, antioxidant capacity, enzyme inhibitory potential, and cytotoxic activity of extracts derived from its aerial parts. Among the tested extracts, the 70% ethanol extract contained the highest total phenolic content. A total of 38 compounds, mainly phenolic acids and flavonoids, were identified by HPLC-ESI-MS/MS analysis. The aqueous extract contained the highest levels of individual phenolic compounds, particularly ferulic acid and p-coumaric acid. The 70% ethanol extract showed the strongest antioxidant activity in all assays. The ethyl acetate extract exhibited the highest acetylcholinesterase and α-amylase inhibitory activities. Cytotoxicity assays revealed that the 70% ethanol extract was active against A549 lung cancer cells with an IC50 value of 56.77 µg mL−1 and a selectivity index of 1.6. In vivo zebrafish developmental toxicity assays demonstrated dose-dependent embryotoxic effects. Early exposure (0 hpf) caused increased mortality, reduced hatching, and morphological abnormalities, such as axial curvature and pericardial edema, whereas exposure at 72 hpf showed markedly reduced sensitivity. Overall, the findings suggest that R. raphanistrum is a promising natural source of bioactive compounds that could be used in the nutraceutical, pharmaceutical and cosmeceutical industries.
