| Abstract: | Two bioactive compounds were isolated from Daphniphyllum angustifolium Hutch. and purified by column chromatography with D101 macroporous resin adsorption, Sephadex LH-20 and Pre-HPLC. The compounds were characterized by UV, ESI-MS, 1H NMR, 13C NMR and 2D NMR (HSQC, HMBC and NOESY) techniques. The 1H NMR and 13C NMR signals of the compounds were assigned. Their structures were elucidated as 5,4′-dihydroxy flavanone-7-O-α-L-rhamnopyranosyl (1→2) -β-D-glucopyranoside and 7,4′-dihydroxy-isofavone-8-C-β-D-glucopyranoside, respectively. |
