Four new phenolic glycosides, including two flavonoid glycosides (1 and 2) and two lignan glycosides (3 and 4), were isolated from the traditional Chinese medicine formula, Baoyuan decoction. Their structures were established by detailed analysis of the NMR and HR-ESI-MS spectroscopic data and their absolute configurations were determined by the experimental electronic circular dichroism data as well...
Three new flavonoid glycosides, (3R)-(+)-isomucronulatol-2′-O-β-D-glucopyranoside (1), (3R)-(−)-isomucronulatol-7-O-β-D-apiofuranosyl(1→2)-β-D-glucopyranoside (2), and (2S)-(−)-7,8-dihydroxylflavanone-4′-O-β-D-apiofuranosyl(1→2)-β-D-glucopyranoside (3), along with eight flavanones (4, 8, 10, 12, 15, 16, 21, and 24), four isoflavones (5, 11, 13, and 23), four chalcones (6, 14, 17, and 18), two isoflavans...
