Abstract:
:Two new neolignan glucosides named (7S, 8R)-4,7,9,9'-tetrahydroxy-3,3'-dimethoxyl-7'-oxo-8-4'-oxyneolignan-4-O-β-D-glucopyranoside and (7'S, 8'R, 8S)-4,4',9'-trihydroxy-3,3'-dimethoxy-7',9-epoxylignan-7-oxo-4-O-β-D-glucopyranosyl-4'-O-β-D-glucopyranoside, together with two small molecular peptides named 3-benzyl-6-(1-hydroxyethyl)-2,5-piperazinedione and 3-benzyl-2,5-piperazinedione, were isolated from the extract of Arctii Fructus. Their structures and absolute configurations were elucidated by various spectroscopic methods (IR, HR-ESI-MS, 1D and 2D NMR, and CD).
