A new unsaturated fatty acid (E)-7,9-diene-11-carbonyl stearic acid (1) and a new lignan 8'-acetyl olivil (2), together with 14 known compounds (3-16), were isolated from the stem of Urtica fissa E. Pritz. Their structures were elucidated by spectroscopic and
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
The purpose of this work was to determine the chemical profile of stinging nettle and to provide an insight into the mechanisms by which it ameliorates the immune response. Qualitative and quantitative liquid chromatography tandem mass spectrometry analyses indicated that phenolic acids
