RESUMEN
Three new secolignan glycosides {3,4-trans-4-[bis(3,4-dimethoxyphenyl)methyl]-2-oxotetrahydrafuran-3-yl}methyl-O-ß-glucopyranoside (1), {3,4-trans-4-[(3-methoxy-4-hydroxyphenyl)(3,4-dimethoxyphenyl)methyl]-2-oxotetrahydrafuran-3-yl}methyl-O-ß-glucopyranoside (2) and {3,4-cis-4-[(3-methoxy-4-hydroxyphenyl)(3,4-dimethoxyphenyl)methyl]-2-oxotetrahydrafuran-3-yl}methyl-O-ß-glucopyranoside (3) were isolated from the roots of Urtica fissa E. Pritz. Their structures were identified by spectral methods including 1D NMR, 2D NMR and HR-EI-MS.
