    Solvent effect in H-1 NMR spectra of 3 '-hydroxy-4 '-methoxy isoflavonoids from Astragalus membranaceus var. mongholicus[Reference: WebLink]
    Four 3'-hydroxy-4'-methoxy-isoflavonoids: calycosin-7-O-beta-D-glucopyranoside (1), calycosin (2), pratensein-7-O-beta-D-glucopyranoside (Pratensein 7-O-glucopyranoside ,3), and pratensein (4) were isolated from Astragalus membranaceus var. mongholicus, among which compound 4 was obtained from this plant for the first time. The solvent effect obscuring (1)H signal patterns of B ring of compounds 1-4 was reported to avoid mis-assignments. Previously reported NMR data of compounds 1 and 2 were corrected based on 1D and 2D NMR experiments.
