Oats and their seeds, stems, and leaves are approved for use as safe food ingredients. Oat seedlings are environmentally friendly and are becoming increasingly popular as they provide several health benefits. We used the UPLC-CAD to quantitatively analyze isolated compounds (1–11) between 15 cultivars of oat seedlings and their harvest time. Maximum average amount of total contents of isolated compounds was observed after the harvest time of 5 days (4711.3 mg/100 g), while the minimum was observed after the harvest time of 7 days (4184.8 mg/100 g). We demonstrated that all isolated compounds (1–11) showed neuraminidase inhibitory effects, with 6 and 7 being the most active with IC₅₀ values of 3.7 and 20.5 µM, respectively. High content of compounds 6 and 7 was observed (2306.6 mg/100 g) in the Dahan cultivar at 9 days, indicating potential good cultivars with a high content of active compounds and neuraminidase inhibition activity.

燕麦及其种子、茎和叶被批准用作安全食品成分。燕麦幼苗对环境无害，并且因其提供多种健康益处而变得越来越受欢迎。我们使用 UPLC-CAD 对15 个燕麦幼苗品种及其收获时间之间的分离化合物 ( 1 – 11 )进行了定量分析。在 5 天的收获时间后观察到分离化合物总含量的最大平均量 (4711.3 mg/100 g)，而在 7 天的收获时间后观察到最小值 (4184.8 mg/100 g)。我们证明所有分离的化合物 ( 1 – 11 ) 都显示出神经氨酸酶抑制作用，其中6和7对 IC 最活跃_{50 个}值分别为 3.7 和 20.5 µM。在第9天时在大汉品种中观察到高含量的化合物6和7（2306.6 mg/100 g），表明具有高活性化合物含量和神经氨酸酶抑制活性的潜在优良品种。
