Determination of Constituents of Extract of Celtis tournefortii Lam. by LC-MS/MS, Investigation of Enzyme Inhibition, Antimicrobial and Anticancer Effects

Phytochemicals found in extracts obtained from plants are very important bioactive constituents. In this study, phytochemicals in extract content obtained from Celtis tournefortii .Lam. tree (CT) leaves were determined by a LC-MS method. The constituents with the major concentrations was found rutin (2479.89 µg ml-1), coumarin (1241.68 µg ml-1), biochanin A (1026.42 µg ml-1), shikimic acid (477.32 µg ml-1), chlorogenic acid (300.76 µg ml-1). The suppressive effects of CT extract on the growth of pathogenic strains were studied by microdilution method. It was observed that it caused suppression on the strains in the concentration range of 2.00-8.00 µg ml-1. The inhibition effects of the extract on acetyl cholinesterase and glutathione-S transferase enzyme activities were investigated, and 50% inhibitory values of enzyme activity were found to be 13.58 and 13.86, respectively. Using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay method, the cell viability suppressive effects of CT leaf extract were studied in healthy skin fibroblast cells as well as ovarian, colon and brain cancer cells. It was observed that they created a 42%, 4.27%, and 14.29% suppression in cells, respectively.
