In the present investigation the acetone extracts of three macroalgae, Cystoseira amentacea, Cystoseira barbata and Cystoseira compressa, were tested for antioxidant, antimicrobial and cytotoxic potential. As a result of the study, C. amentacea extract had more potent free radical scavenging activity (IC<sub>50</sub> = 409.81 μg/mL) than C. barbata and C. compressa extracts. For reducing power, measured values of absorbance varied from 0.0352 to 0.8873. The IC<sub>50</sub> values for superoxide anion scavenging activity for different extracts were 521.45–976.62 μg/mL. Total phenol and flavonoid contents in extracts were 39.96–81.28 μg PE/mg and 20.85–64.58 μg RE/mg respectively. Further, all three Cystoseira species exhibited a similar antimicrobial activity. The lowest MIC value (0.312 mg/mL) was shown in the extract obtained from C. compressa against Bacillus subtilis. Finally, extract of C. amentacea expressed the strongest cytotoxic activity toward tested cell lines with IC<sub>50</sub> values ranging from 94.72 to 186.55 μg/mL. Based on these results, it can be stated that the tested macroalgae can be used as potential natural antioxidants and antimicrobial and cytotoxic agents.
