Fifteen flavonoids were isolated and identified by macroporous resin column chromatography, polyamide column chromatography, silica gel column chromatography, ODS column chromatography and preparative liquid chromatography from the ethanol extract Turpinia arguta. Their structures of these flavonoids were identified by NMR and mass spectrometry as argutoside F (1), luteolin-7-O-α-L-rhamanopyranosyl-(1→2)-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (2), nuezhenoside (3), acacetin-7-O-α-L-rhamnopyranosyl-(1→2)-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (4), apigenin (5), quercetin (6), quercetin-3-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (7), rhoifolin (8), luteolin-7-O-α-L-rhamanopyranosyl-(1→2)-β-D-glucopyranoside (9), acacetin-7-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (10), luteolin-7-O-β-D-glucopyranoside (11), luteolin (12), neodiosmin (13), apigenin-7-O-rutinoside (14), and quercetin-3-O-α-L-arabinopyranoside (15). Compound 1 is new, whereas compound 2, 7, 9, 13-15 were obtained from this plant for the first time.
