“…C and 1 H NMR chemical shifts of compound 3 agreed well with the previously reported 13 C NMR (Achenbach and Benirschke 1997) and 1 H NMR spectral data (Shimomura et al 1988). The ESIFTICR mass spectrum, recorded with NaCl, showed the peak of wMqNax q at m/z 369.1267 (C 15 H 22 O 9 Na requires 369.1156).…”

A new lignan glycoside, 5-(3″,4″-dimethoxy-phenyl)-3-hydroxy-3-(4'-hydroxy-3'-methoxybenzyl)-4-hydroxymethyl-dihydrofuran-2-one 4'-O-α-L: -rhamnopyranoside (1), with seven known compounds, compound 2, koaburside, icariside E(4), cleomiscosin C, cleomiscosin D, scopoletin, and 5'-demethylaquillochin, were isolated from the EtOH extract of the wood of Acer saccharum (Aceraceae). Their structures were determined by 1D and 2D nuclear magnetic resonance (NMR) and mass spectroscopy analysis. All of the isolated compounds, 1-8, were tested for their antioxidant activity in superoxide dismutase (SOD)-like assay.

“…The Ca/Cb data of arylglycerol b-guaiacyl ether appeared at 72.1/84.4 (C-7ЉЉ/C-8ЉЉ) was indicative of erythro form. 22) The known phenolic compounds were classified to two phenolic glycosides (3,4,5-trimethoxyphenyl-b-D-glucopyranoside 23) and 1-[a-L-rhamnopyranosyl-(1→6)-b-D-glucopyranosyloxy]-3,4,5-trimethoxybenzene, 24) ) four flavonoids (tricin, rutin, 25) nicotiflorin, and myricetin-3-O-rutinoside 26) ), and six lignans (lyoniside, 27) 29) and hedyotisols A-C 21) ), and their structures were identified by comparison of spectroscopic data with those in literature. All of the known compounds were isolated from mangrove plants for the first time.…”
