Popis:	A novel flavonoid named mopanolchin (1), together with seven known flavonoids, was isolated by various chromatographic techniques and spectroscopic methods from the EtOAc extract of the roots of Lysidice rhodostegia Hance. The structure of the new compound was elucidated as 1″-(4-hydroxy-3, 5-dimethoxy)phenyl-2″-hydroxymethyl-dioxino [4′, 5′,1″, 2″]mopanol (1) on the basis of spectral analysis. The known compounds were identified as (-)-epicatechin-3-O-gallate (2), epicatechin (3), naringenin (4), eriodictyol (5), luteolin (6), 7, 3′, 4′-trihydroxyflavone (7) and (-)-robinetinidol (8). Key words: flavonoids; Lysidice rhodostegia; mopanolchin. (Managing editor: Wei WANG)
