Total anthocyanins were extracted from eleven sweet cherry cultivars grown in Sakarya, Turkey. In vitro inhibition effects of extracted total anthocyanins on purified carbonic anhydrase I and II were investigated by using CO2 as a substrate. The results showed that all extracted total anthocyanins inhibited the hCA I and hCA II enzyme activities. Among all cultivars, ‘Merton Premier’ was found to be the most active one against both hCA I (IC50?=?0.83?µg/mL) and hCA II (IC50?=?1.16?µg/mL). Additionally, the DPPH activities of the extracts were investigated as antioxidant properties. The results exhibited that ‘Churchill’ and ‘Merton Premier’ have high antioxidant activity with 74.102% and 73.503% DPPH activity, respectively.
