Due to the richness of bioactive substances and easy accessibility, sea-buckthorn can be an ingredient of currently popular functional food supporting anti-cancer therapy. Low-polarity fractions from fruit (OL), twigs (GL) and leaves (LL) were investigated. Compared to the previous scientific reports a more detailed analysis of the chemical composition of individual fractions was performed. Cytotoxicity of low-polarity fractions has been investigated and activity compared in human tumor and normal cells cultured in vitro. The genotoxicity and pro-apoptotic properties of low-polarity fractions were also followed on selected cell lines that had proved to be the most sensitive. In the proposed research model being tested, low-polarity fractions act cytotoxically, even 3 times more strongly in cancer cells than normal ones. Measurement of caspase 3/7 activity indicated that cell death occurs through apoptosis. Furthermore, high concentrations of low-polarity fractions have moderate genotoxic properties. Data obtained on the biological properties of low-polarity fractions from sea-buckthorn show that these fractions can potentially support cancer cells elimination. Phytotochemical analysis indicates the key role of the triterpenoids in this process.
