In this study; it was aimed to investigate the anticancer and cytotoxic activities on DU-145 prostate cancer and MCF-7 breast cancer cell lines and WI-38 human fibroblast cell line of essential oil (Nioli) obtained from Melaleuca viridiflora Sol. ex Gaertn. plant and its antimicrobial effects on various bacteria and yeast cells. Content analyzes of Nioli essential oil were made by Gas Chromatography-Mass Spectrometry (GK-KS). The antimicrobial effects of the essential oil were determined using Disk Diffusion and Minimum Inhibition Concentration (MIC) tests. Its cytotoxic effects were determined by the XTT (2,3-bis-(2-methoxy-4-) nitro-5)-sulfophenyl)-2H-tetrazolium-5-carboxanilide) test; were investigated at different concentrations in breast cancer (MCF-7), prostate cancer (DU-145) and healthy human fibroblast (WI-38) cell lines. In the disc diffusion method of essential oil; It was determined that it formed an inhibition zone against Klebsiella pneumoniae bacteria at 200, 100, 50, 25 and 12.5 µg/mL concentrations, and against Candida albicans yeast at 200 and 100 µg/mL concentrations. Nioli essential oil showed the highest antibacterial effect against Bacillus cereus. While it was moderately effective against Pseudomonas aeruginosa and Candida albicans, it reached MIC values effective against other bacteria. It was observed that the anticancer activity of Nioli essential oil was more effective in DU-145 prostate cancer cells compared to MCF-7 breast cancer cells, and it had no toxicity in WI-38 healthy human fibroblast cells.
