ABSTRACT
Introduction:
Flavonoids belong to phytotherapeutics with a wide spectrum of pharmacological activity. It has been proven that flavonoids possess properties that can inhibit the development of cancer by inducing cells into the programmed cell death process. The aim of the work was to demonstrate the apoptotic, antiproliferative and cytotoxic properties of selected flavonoids.

Material and methods:
The test material was the human primary hepatocellular carcinoma SK Hep-1 cell line. The tested compounds were assessed for cytotoxicity with the MTT assay. The next step was to evaluate the level of protein expression from the Bcl-2 family using the human Bcl-2 ELISA test.

Results:
The compound with the strongest cytotoxic properties confirmed by the MTT test is chrysin, the IC50 value of which was 316.67 μM/L. In the case of all the tested compounds, apoptotic processes were confirmed by the human Bcl-2 ELISA test. The highest level of Bcl-2 protein expression occurred after 48 hours after the administration of chrysin, hesperidin, naringin and kaempferol.

Conclusions:
On the basis of the obtained research results, it can be concluded that the studied flavonoids (chrysin, hesperidin, naringin, kaempferol) exhibit cytotoxic, proapoptotic and antiproliferative properties in relation to SK Hep-1 hepatoma cells.
