摘要

Three Dracocephalum (Lamiaceae) species growing in Russia, D. argunense Fisch. ex Rchb., D. austriacum L., and D. peregrinum L., were investigated and afforded 26 phenolic compounds, including four new flavonoids 14. Compounds 14 were identified using UV and NMR spectroscopy and mass spectrometry as acacetin 7-O-(2″-O-sophorotriosyl)rutinoside (dracocephoside I, 1), acacetin 7-O-(2″-O-sophorotriosyl)rutinoside 6‴-O-acetate (dracocephoside II, 2), acacetin 7-O-(2″-O-sophorosyl)rutinoside 4‴-O-acetate (dracocephoside III, 3), and acacetin 7-O-(2″-O-glucosyl)rutinoside 2‴-O-acetate (dracocephoside IV, 4).
