[Flavonoids from Picris davurica].[Pubmed: 28875640]
Eleven compounds were purified from the anti-inflammatory extract of Picris davurica by column chromatograph on HP20 macroporous resin, MCI, sephadex LH-20 and ODS.Their structures were determined by the spectra data of NMR and MS as isoestin 7-O-β-D-glucopyranosyl-2'-O-α-L-arabinopyranoside(1), isoetin-7-O-β-D-glucopyranosyl-2'-O-β-D-xyloypyranoside(2), isoetin-7-O-β-D-glucopyranosyl-2'-O-α-D-glucopy- ranoside(3), isoetin 5'-O-β-D-glucopyranoside(4), isoetin-2'-O-β-D-xyloypyranoside(5), isoetin-4'-O-β-D-O-β-D-glucopyranoside(6), isoetin-7-O-β-D-glucopyranoside(7), isoestin-2'-O-α-L-arabinopyranoside(8), luteolin-7-O-β-D-glucopyranosie(9), isoetin(10) and luteolin (11). All compounds were isolated from this plantfor the first time.Among them, compounds 1-8 were isolated from the genus Picris for the first time.
