Abstract Studies on the chemical constituents of roots of Urtica triangularis HAND-MASS have led to the isolation of four new compounds. The structures, including the absolute configurations, of these constituents have been elucidated through spectral studies including (1)H-NMR, (13)C-NMR, 2D-NMR experiments (heteronuclear single-quantum coherence, heteronuclear multiple bonding connectivity and nuclear Overhauser effect spectroscopy), high resolution mass spectroscopy (HR-MS) and circular dichroism as (-)-4-methoxy-8'-acetyl olivil, (-)-4-methoxy-8'-acetyl olivil-4-O-alpha-arabinopyronosyl-(1-->6)-beta-glucopyranoside, (-)-olivil-9-O-beta-glucopyranoside and cyclo-olivil-9-O-beta-glucopyranoside.
