ABSTRACT

<p><b>OBJECTIVE</b>To study the contents of the flavonoids in the extract of Lespedeza virgate.</p><p><b>METHODS</b>The constituents in the ethanol extraction of the aerial parts of Lespedeza virgate were isolated and purified using column chromatography, and the isolated compounds were identified according to their physicochemical and spectral data.</p><p><b>RESULTS AND CONCLUSION</b>Eight flavonoids were isolated and identified as tricin (I), kaempferol (II), apigenin (III), kaempferitrin (IV), morin (V), luteolin (VI), quercetin-3-O-alpha-L-rhamnoside (VII), chrysoeriol-7-rutinoside (VIII). The compounds I, II, III, V and VI were isolated for the first time from the plant, and the compound VIII was isolated from this genus for the first time.</p>
