Investigation of The Antibacterial and Anticarcinogenic Effects of Inula viscosa Methanol and Hexane Extracts

Objective: Inula viscosa is a perennial medicinal plant belonging to the Asteraceae family. This study aimed at investigating the antibacterial and anticarcinogenic activities of methanol and hexane extracts derived from I. viscosa . Methods: The antibacterial activity of different concentrations of I. viscosa methanol (1.56-800 mg/ml) and hexane (0.19-100 mg/ml) extracts was tested using the disc diffusion method. Listeria the hexane extract were 400 mg/ml for L. monocytogenes , E. coli ve K. pneumoniae , and 100 mg/ml for M. luteus . MBC values were similar to MIC values. IC50 values for MDA-MB-231 and HT-29 cells were 25 mg/ml and 200 mg/ ml for the methanol extract, and 6.25 mg/ml and 12.5 mg/ml for the hexane extract, respectively. Depending on increased concentration levels, the presence of necrotic and early apoptotic cells was observed among MDA-MB-231 and HT-29 cells. Conclusion: Methanol and hexane extracts of I. viscosa were found to have antibacterial effects on the studied bacteria and anticarcinogenic activity on MDA-MB-231 and HT-29 cells. Conducting further studies to demonstrate the effects of these extracts on different cancer cell lines and bacterial strains will contribute to the field of
