Twenty land mosses were extracted by double maceration and ultrasonic extraction techniques using the mixture of 80% ethanol and water. The obtained extracts were analyzed using thin-layer chromatography (TLC) with silica gel (the mobile phase was consisted of ethyl acetate–formic acid–acetic acid–water, 14.0:1.5:1.5:2.0, v/v) and RP-18 (the composition of eluent methanol–water–formic acid, 7.0:2.5:0.5, v/v) chromatographic plates. After developing and drying, the plates were sprayed using the Naturstoff reagent, and after drying, the chromatograms were photographed and the obtained images were processed using the ImageJ program. Principal component analysis was performed to confirm the chemical similarity between the studied moss extracts. The cytotoxic activity of the ethanolic extracts of Bryophyta species was studied using the cell lines CCRF/CEM and CEM. For most of the moss samples, the cytotoxic activity was confirmed.
