Four phenolic compounds were isolated from Beta vulgaris L. var. cicla L. (Chenopodiaceae). These isolated compounds were identified as N-cis-feruloyl 3-O-methyldopamine (1), N-cis-feruloyl tyramine (2), N-trans-feruloyl 3-O-methyldopamine (3), N-trans-feruloyl tyramine (4), respectively, by spectroscopic analysis. The phenolic amides 1-4 exhibited modest inhibitory activity on LPS-activated nitric oxide production dose-dependently in RAW 264.7 cells.
