HUVEC cell viability, measured with the MTT assay, after pre-treatment with the oat phenolics and metabolites (0.1, 1 and 10 µM) ferulic acid (FA) isoferulic acid (IFA), dihydroferulic acid (DHFA), FA glucuronide (FAG), DHFA glucuronide (DHFAG), IFA sulfate (IFAS), avenanthramide A (AVN-A) avenanthramide B (AVN-B) avenanthramide C (AVN-C) for 24 h. Data are expressed as percentage of control values (100%) and reported as average ± SEM of 4 independent experiments performed in triplicate. p > 0.05 vs. control (n = 12).
