Melanoma is a huge worldwide health problem that must be handled more effectively with better therapeutic options. As a result, new treatment drugs are required to treat this condition. The goal of this study was to investigate the cytotoxic activity of the anthraquinone-rich fractions obtained from Asphodelus microcarpus against human melanoma cell A375. On these melanoma cell lines; the cytotoxicity of these fractions had never been studied before. Liquid chromatography linked to mass spectrometry (LC-MS-MS) and Nuclear Magnetic Resonance was used to determine the chemical profiles of these fractions. The cytotoxicity of the fractions studied was determined by measuring cell viability and calculating IC50 values. Both ethyl acetate (EtOAC) and the precipitate fractions (PPT) exhibited selective cytotoxicity on human melanoma A 375 cell line with IC50 values of 83 and 65 µg/mL, respectively. The antiproliferative properties of EtOAc fraction and PPT were supported by a noticeable decrease in cell numbers during the G2/M cell cycle arrest. Our findings suggest that the anthraquinone content of A. microcarpus tubers is responsible for its anti-proliferative and apoptotic properties and that further in vivo investigations should be conducted to establish the viability of using them to treat human melanomas.
