文摘
Eleven antioxidative compounds, including five lignin amides, were isolated from the aerial part of Tetragonia tetragonioides (New Zealand spinach) using 1,1-diphenyl-2-picrylhydrazyl radicalscavenging assay-guided purification. The structures were determined by nuclear magnetic resonance and electrospray ionization-mass spectroscopy. These compounds were identified as methyl linoleate (1), methyl coumarate (2), methyl ferulate (3), 1-O-stearoyl-3-O-β-D-galactopyranosyl-sn-glycerol (4), 1-O-caffeoyl-β-D-glucopyranoside (5), N-trans-caffeoyltyramine (6), cannabisin B (7), cannabisin A (8), Ntrans-feruloyltyramine (9), N-cis-feruloyltyramine (10), and N-trans-sinapoyltyramine (11). Compounds 1, 2, 4, 5, and 8-11 were isolated for the first time from this plant.
