Neuroblastoma is the most common solid tumor in children. New treatment approaches are needed because of the harmful
side effects and costs of the methods used in the treatment of neuroblastoma. Medicinal and aromatic plants are important
for new treatment approaches due to their minimal side effects and economic advantages. Therefore, the present study was
carried out to examine the cytotoxic effect of Chaerophyllum macropodum extract on human neuroblastoma (SH-SY5Y) and
fibroblast (HDFa) cell lines. 3-[4,5-dimethylthiazole-2-yl]-2,5-diphenyltetrazolium bromide (MTT) and lactate dehydrogenase
release (LDH) assays were used to determine the cytotoxic effect of C. macropodum. The extracts were analyzed for
their phenolic content by HPLC–PDA. Major components were determined as 63.600% o-coumaric acid, 15.606% catechine
hydrate, 8.713% rosmarinic acid, 4.376% clorogenic acid, and 3.972% salicylic acid. The obtained results from cytotoxicity
testing revealed that C. macropodum exerted a significant cytotoxic effect on human neuroblastoma cells at all tested
concentrations (p < 0.05). But it did not lead to any cytotoxic potential on human fibroblasts. As a result, the obtained data
clearly revealed C. macropodum exerted a selective cytotoxic action on neuroblastoma cells for the first time.
