Natural products with bioactive components are widely studied on various cancer cell lines for their possible cytotoxic effects, recently. Among these products, honey stands out as a valuable bee product containing many active phenolic compounds and flavonoids. Numerous types of multifloral honey and honeydew honey are produced in Turkey owing to its abundant vegetation. Therefore, in this study, we investigated the cytotoxic effects of particular tree-originated honeys from chestnut, cedar, pine, and multifloral honey on cell lines representing different types of the most common cancer of women, breast cancer, MCF7, SKBR3, and MDAMB-231, and fibrocystic breast epithelial cell line, MCF10A as a control. All honey samples were analyzed biochemically. The dose- (1, 2.5, 5, 7.5, and 10 mu g/mL) and time (24th, 48th, and 72nd hours)-dependent effects of ethanol/water solutions of the honey samples were scrutinized. Cell viability/cytotoxicity was evaluated by the water soluble tetrazolium Salt-1 (WST-1) method. Apoptotic status was detected by Annexin V-PI assay using FACSCalibur. The statistical analysis was performed using GraphPad Prism 6 and the clustering data analysis with the R programming language. The biochemical analyses of the honey samples showed that the tree-originated honey samples contained more total phenolic compounds than the multifloral honey. Phenolic content of the honey types increases in order of multifloral, pine, cedar, and chestnut, respectively, which is compatible with their cytotoxic affectivity and dark color. In addition, the antioxidant capacity of the studied honey types was observed to increase in order of multifloral
