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.

从土耳其萨卡里亚种植的 11 个甜樱桃品种中提取总花青素。以CO ₂为底物，研究了提取的总花青素对纯化的碳酸酐酶I和II的体外抑制作用。结果表明，所有提取的总花青素均抑制hCA I和hCA II酶活性。在所有品种中，'Merton Premier' 被发现对 hCA I (IC ₅₀  = 0.83 µg/mL) 和 hCA II (IC ₅₀  = 1.16 µg/mL) 都是最有效的。此外，还研究了提取物的 DPPH 活性作为抗氧化特性。结果表明，“Churchill”和“Merton Premier”具有较高的抗氧化活性，DPPH 活性分别为 74.102% 和 73.503%。
