Berries of four gooseberry (Ribes uva-crispa L.) cultivars of Invicta, Rixanta, Karat and Black Negus and five currant (Ribes L.) cultivars of NS 11, Focus, Ben Gairn, Otelo and Viola were evaluated as potential sources of bioactive compounds with extraordinary antioxidant activity. Their total phenolic, flavonoid and anthocyanin contents were determined in the range of 3.52-30.77 g GA.kg, 2.83-17.35 g RE.kg and 0.03-186.12 mg COG.100 g, respectively. Furthermore, quantification of phenolic compounds and vitamins was established by high-performance liquid chromatography-diode array detection. Flavonoids were the most abundant phenolic substances in the range of 345.0-3726.5 mg.kg. Ascorbic acid and vitamin E were established in the amounts of 6.2-14.04 g.kg and 0.43-12.85 mg.kg, respectively. Considering all analyzed factors and antioxidant activities determined by various methods (DPPH, ACW and ACL), red gooseberry Black Negus and black currant Otelo were the most significant cultivars.
对四种醋栗（ Ribes uva-crispa L.）品种——Invicta、Rixanta、Karat 和 Black Negus，以及五种黑穗醋栗（ Ribes L.）品种——NS 11、Focus、Ben Gairn、Otelo 和 Viola 的浆果进行了评估，以确定它们是否具有非凡抗氧化活性的生物活性化合物的潜在来源。它们的总酚、类黄酮和花青素含量分别在 3.52-30.77 g GA.kg、2.83-17.35 g RE.kg 和 0.03-186.12 mg COG.100 g 范围内。此外，通过高效液相色谱-二极管阵列检测建立了酚类化合物和维生素的定量分析。类黄酮是最丰富的酚类物质，含量在 345.0-3726.5 mg.kg 范围内。抗坏血酸和维生素 E 的含量分别为 6.2-14.04 g.kg 和 0.43-12.85 mg.kg。考虑到所有分析因素和通过各种方法（DPPH、ACW 和 ACL）测定的抗氧化活性，红色醋栗品种 Black Negus 和黑色黑穗醋栗品种 Otelo 是最显著的品种。
