[Isolation and properties of Sarothamnoside, a novel isoflavone glycoside from various Sarothamnus species].
Sarothamnoside (genistein 7,4'-di-O-[4-O-beta-D-glucopyranosyl-beta-D-apiofuranoside]), a novel isoflavone glycoside, has been isolated from Sarothamnus scoparius and S. patens seeds. The structure, in agreement with acid and enzymatic hydrolysis experiments, has been unambiguously determined, using spectral methods: SM, (1)H NMR and (13)C NMR. (1)H NMR spectra showed the beta configuration of the two apioses, whereas (13)C NMR provided evidence of the sugar linkages.
