title: [Studies on chemical constituents of Meconopsis quintuplinervia Regel].
abstract: Seven flavonoids were isolated from Meconopsis quintuplinervia Regel for the first time, and their structures were elucidated as quercetin (I), dihydroquercetin (II), luteolin (III), chrysoeriol (IV), apigenin (V), huazhongilexone (VI) and hydnocarpin (VII) by spectroscopic methods including IR, EIMS, 1D- and 2D-NMR techniques.
