Two new secolignans, {(3 S ,4 S )‐4‐[bis(4‐hydroxy‐3‐methoxyphenyl)methyl]‐2‐oxotetrahydrofuran‐3‐yl}methyl β ‐ D ‐glucopyranoside ( 1 ) and its stereoisomer {(3 S ,4 R )‐4‐[bis(4‐hydroxy‐3‐methoxyphenyl)methyl]‐2‐oxotetrahydrofuran‐3‐yl}methyl β ‐ D ‐glucopyranoside ( 2 ), have been isolated from the roots of Urtica fissa E. Pritz . Their structures were determined based on spectroscopic methods (HR‐MS, 1D‐ and 2D‐NMR, HMBC, HSQC, and NOESY).
