对生长在韩国水原的45个商业品种（39个北方高丛蓝莓和6个半高丛蓝莓）的蓝莓果实进行了果实大小、可溶性固形物含量、可滴定酸度、总花青素含量、总酚含量和抗氧化活性的分析。45个蓝莓品种果实性状差异较大。果重0.9 ~ 3.6 g，可溶性固形物含量8.3 ~ 14.3 Brix，可滴定酸0.8%~ 3.6%。抗氧化活性范围从0.7至2.1毫克槲皮素当量每克新鲜浆果在不同的蓝莓品种。在45个蓝莓品种中，观察到大量的花青素和多酚，以及高抗氧化活性的'埃利奥特'，'鲁贝尔'，'兰考克斯'，和'蓝宝石'。
Blueberry fruits from 45 commercial cultivars (39 northern highbush and 6 half highbush blueberry) grown in Suwon, Korea were analyzed for fruit size, soluble solids content, titratable acidity, total anthocyanin content, total phenolic content, and antioxidant activity. Fruit characteristics varied widely among the 45 blueberry cultivars. Fruit weight ranged from 0.9 to 3.6 g, soluble solids content from 8.3 to 14.3 degrees Brix, and titratable acidity from 0.8% to 3.6%. Antioxidant activity ranged from 0.7 to 2.1 mg of quercetin equivalents per gram of fresh berries in different blueberry cultivars. Among the 45 blueberry cultivars, high amounts of anthocyanins and polyphenols, and high antioxidant activity were observed in 'Elliott', 'Rubel', 'Rancocas', and 'Friendship'.
