Abstract EN
In the present investigation the acetone extracts of macroalgae Ulva lactuca and Enteromorpha intestinalis were tested for antioxidant, antimicrobial and cytotoxic potential.
Antioxidant activity was evaluated by measuring the scavenging capacity of tested samples on DPPH and superoxide anion radicals, reducing the power of samples and determination of total phenolic and flavonoid compounds in extracts.
As a result of the study, U.
lactuca extract was found to have a better free radical scavenging activity (IC50= 623.58 lg/ml) than E.
intestinalis extract (IC50= 732.12 lg/ml).
Moreover, the tested extracts had effective ferric reducing power and superoxide anion radical scavenging.
The total content of phenol in extracts of U.
lactuca and E.
intestinalis was 58.15 and 40.68 lg PE/mg, while concentrations of flavonoids were 39.58 and 21.74 lg RE/mg, respectively.
Furthermore, among the tested species, extracts of U.
lactuca showed a better antimicrobial activity with minimum inhibitory concentration values ranging from 0.156 to 5 mg/ml, but it was relatively weak in comparison with standard antibiotics.
Bacillus mycoides and Bacillus subtilis were the most susceptible to the tested extracts.
Contrary to this Aspergillus flavus, Aspergillus fumigatus and Penicillium purpurescens were the most resistant.
Finally, cytotoxic activity of tested extracts was evaluated on four human cancer cell lines.
Extract of E.
intestinalis expressed the stronger cytotoxic activity towards all tested cell lines with IC50 values ranging from 74.73 to 155.39 lg/ml.
