Six new compounds including four flavonoids (1–3, 5) and two iridoids (4 and 6) were found in three Veronica species growing in eastern Siberia. Their structures were studied by UV and NMR spectroscopy and mass spectrometry. 6-Hydroxyluteolin-7-O-(6″-O-isoferuloyl)-β-D-glucopyranoside (veroniside A, 1) was isolated from V. daurica Steven; 6-hydroxyluteolin-7-O-(6″-O-isovanilloyl)-β-D-glucopyranoside (veroniside B, 2) and scutellarein-7-O-(6″-O-vanilloyl)-β-D-glucopyranoside (veroniside C, 3), from V. spicata subsp. incana (L.) Walters (V. incana L.); and 6-O-sinapoyl catalpol (veroniside D, 4), scutellarein-7-O-(6″-O-protocatechoyl)glucoside (veroniside E, 5), and 6-O-isoferuloyl asystasioside E (veroniside F, 6), from V. longifolia L.
