To explore functional food ingredients from green seedlings, the bioactive components (phenolic compounds and γ-aminobutyric acid) and antioxidant activities (DPPH radical scavenging ability, ABTS radical scavenging ability and reducing power) of three green seedlings, including coix seed seedling (CSS), highland barely seedling (HBS) and naked oats seedling (NOS) cultivars were respectively measured and deeply compared. Results indicated that CSS showed the highest contents of the total polyphenol (183.35 mg/100 g), total flavonoid (348.68 mg/100 g), and γ-aminobutyric acid (54.17 mg/100 g). As expected, CSS also exerted the highest level of antioxidant activity, followed by HBS and NOS. Moreover, CSS possessed the potential of stimulating immune responses, including promoting proliferation and strengthening phagocytosis function of RAW264.7 cells. Taken together, all results suggested that the three green seedlings, especially CSS could be used as natural ingredients for functional food.
为了从绿苗中探索功能性食品成分，分别测定并深入比较了三种绿苗（薏苡仁苗、青稞苗和裸燕麦苗）的生物活性成分（酚类化合物和γ-氨基丁酸）和抗氧化活性（DPPH 自由基清除能力、ABTS 自由基清除能力和还原能力）。结果表明，CSS 表现出最高的总多酚（183.35mg/100g）、总黄酮（348.68mg/100g）和γ-氨基丁酸（54.17mg/100g）含量。不出所料，CSS 也表现出最高水平的抗氧化活性，其次是 HBS 和 NOS。此外，CSS 具有刺激免疫反应的潜力，包括促进 RAW264.7 细胞的增殖和增强吞噬功能。综上所述，所有结果表明，三种绿苗，尤其是 CSS，可用作功能性食品的天然成分。
