Abstract: | From the aerial parts of Lupinus hartwegii, two new flavone C-glycosides apigenin-7-O-beta-apiofuranosyl-6, 8-di-C-beta-glucopyranoside (1) and apigenin-7-O-beta-apiofuranosyl-6-C-beta-glucopyranosyl-8-C-(6z.qprime;-O-E-feruloyl)- beta-glucopyranoside (2) have been isolated together with two known isoflavonoid glucosides genistein-7-O-beta-glucopyranoside (3) and genistein-7, 4'-di-O-beta-glucopyranoside (4) as well as two known compounds ferulic acid 4-O-beta-glucopyranoside (5) and sparteine (6). The structures of the isolated compounds were verified by means of MS and NMR spectral analyses. |
