Abstract

Five new compounds, viz. 3,4-dimethoxyphenyl 2-O-(3-O-methyl-alpha-L-rhamnopyranosyl)-beta-D-glucopyranoside, 4'-hydroxyphenacyl beta-D-glucopyranoside, (2R,3R)-2,3-dihydro-7-hydroxy-2-(4'- hydroxy-3'-methoxyphenyl)- 3-hydroxymethyl-5-benzofuranpropanol 4'-O-(3-O-methyl-alpha-L-rhamnopyranoside), 1-(4'-hydroxy-3'-methoxyphenyl)-2-[4"-(3-hydroxypropyl)-2"-methoxyphe noxy]-1,3-propanediol 4'-O-beta-D-xylopyranoside and 3'-O-methylcatechin 7-O-beta-D-glucopyranoside, together with several known compounds were isolated from the root bark of Picea abies. The structures were elucidated on the basis of chemical and spectroscopic evidence.
