Abstract

Highlights: The contents of 11 isolated compounds from oat seedlings showed differences in 15 cultivars and growth times. The major component of avenacoside B contents exhibited the highest in Dahan cultivar at 9 days (1899.3 mg/100 g). Avenafuranol and avenacoside B showed the highest neuraminidase inhibitory activity with IC50 values 3.7 and 20.5 μM, respectively. Dahan cultivar at 9 day may be a potential healthy food source. Abstract: 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.
