由于浆果中含有高水平的有价值的抗氧化剂，如花青素和酚类化合物，浆果的消费在注重健康的消费者中变得很受欢迎。四个兔眼蓝莓品种（即，Powderblue，Climax，Tifblue和Woodward）有机种植和常规种植的总酚含量（TPC），总花青素含量（TAC）和ORAC活性方面的化学特征和抗氧化能力进行了比较。不管有机和常规种植的蓝莓中的高TPC、TAC和ORAC如何，并非所有有机浆果都显示出比常规浆果显著更高的TPC、TAC和ORAC。化学特征（即，游离酚类化合物和花色苷），鉴定出13种花色苷和7种游离酚类化合物。这项研究证明了有机和传统种植的浆果之间生物活性植物化学物质的细微差异。
Consumption of berries has become popular among health-conscious consumers due to the high levels of valuable antioxidants, such as anthocyanins, and phenolic compounds in berries. Four Rabbiteye blueberry cultivars (i.e., Powderblue, Climax, Tifblue, and Woodward) grown organically and conventionally were compared regarding their chemical profiles and antioxidant capacity in terms of total phenolic content (TPC), total anthocyanin content (TAC) and ORAC activity. Regardless of the high TPC, TAC and ORAC in both organically and conventionally grown blueberries, not all the organic berries showed significantly higher TPC, TAC and ORAC than the conventional berries. The chemical profiles (i.e., the free phenolic compounds and anthocyanins) were determined with aid of HPLC-MS, by which 13 individual anthocyanins and seven free phenolics were identified. This study demonstrated the subtle differences of bioactive phytochemicals between the organically and conventionally grown berries.
