ABSTRACT
Twenty compounds, including a new lignan amide, were isolated from the aerial parts of New Zealand spinach, Tetragonia tetragonoides (Pall.) Kuntze, which is an edible halophyte. These compounds were identified by mass spectrometry and nuclear magnetic resonance experiments to be N-2,3-dihydroxy-3-(3,4-dihydroxyphenol) tyramine (new compound), methyl 4-hydroxybenzoate, syringaldehyde, ethyl 4-hydroxybenzoate, 3,4-dihydroxybenzoic acid, 2,3-dihydroxybenzoic acid, coniferyl alcohol, methyl caffeoate, trans- and cis-coumaroyl-β-ᴰ -glucopyranosides, trans- and cis-feruloyl-β-ᴰ-glucopyranosides, caffeic acid, staphylionoside E, canabiside ᴰ, apocyanol A, megastima-5,7-diene-3,4,9-triol, 1-O-oleoyl-3-O-β-ᴰ-galactopyranosyl-sn-glycerol, 5,50-dimethyl-lariciresinol, and kaempferol 3-O-β-ᴰ-glucopyranoside. These compounds were identified in New Zealand spinach for the first time.
