“…This disease can cause serious changes in the physical and mental health of women 2,3 . In addition to the various therapies used in the oncological treatment of cervical cancer, that is, radio‐, chemotherapy 4 or surgical treatment, plant‐based therapy is often used as an alternative treatment to extend and improve quality of life 5 . Plant‐based compounds that can be used in anticancer therapy are, for example, hydroxyanthraquinones isolated from Rheum officinale Baill., Rheum palmatum L., Aloe Barbadensis Mill., and the subjects of our research: aloe‐emodin, emodin, rhein, physcion and chrysophanol.…”

Chrysophanol is an anthraquinone with proven antitumor activity against several tumor cell lines. However, its effect on cervical cancer cells is still unknown. Therefore, HeLa cells were exposed to various concentrations of chrysophanol and then subjected to biochemical, ultrastructural, and morphological analysis. It has been shown using flow cytometry and MTT reduction assay that chrysophanol has been shown to inhibit cell viability and arrest cells in the G2/M phase of the cell cycle. Using Annexin V/propidium iodide staining, a significant increase in apoptosis was found after chrysophanol treatment on HeLa cells, and this process was mediated by caspases 3/7 with a clear inactivation of the antiapoptotic Bcl‐2 family protein. However, the demonstrated increased number of cells with double‐stranded DNA breaks suggests that chrysophanol also causes DNA damage. By means of electron and fluorescence microscopy, a clear effect of chrysophanol on the intensification of degradation processes, on changes in the structure of the nucleus, endoplasmic reticulum and mitochondria was demonstrated. The changes visible in the mitochondria may be related to the increase in the level of free radicals induced by chrysophanol, which induces apoptosis, inter alia, by increasing the permeability of mitochondrial membranes. The range of observed changes depended on the concentration of anthraquinone was tested.
