Anti-Colorectal Cancer Effects of Medicinal Plants: Euphorbia helioscopia, Ferula elaeochytris, and Sideritis albiflora

Phytochemicals, extracts, and mixtures obtained from plants have been offered as an option for cancer treatment and prevention for modern drug discovery in recent years. For this purpose, in this study, anti-colorectal cancer effects of the hexane, acetone, methanol, and water extracts obtained by sequential extraction from Euphorbia helioscopia L., Ferula elaeochytris Korovin, and Sideritis albiflora Hub.-Mor. on DLD-1 cell line were investigated in vitro by using Alamar blue assay. Dosedependent inhibition was detected in the viability of DLD-1 cell line. In all three plants species, E. helioscopia (IC50: 140.83±0.31 µg/mL), F. elaeochytris (IC50: 67.93±0.12 µg/mL), and S. albiflora (IC50: 85.12±0.10 µg/mL) methanol extracts showed higher anti-colorectal effects on DLD-1 cell line compared to other extracts tested for the same species. In addition, the IC50 value of doxorubicin used as a standard was found as 6.10±0.55 µg/mL. With the results obtained, as the first report highlighting in vitro anti-colorectal cancer effects of the studied plant species on DLD-1 cell line, promising marks were obtained from the analysis of the extracts as anti-cancer sources for plant-derived drug applications.
