New lignan tyramide, phenolics, megastigmanes, and their glucosides from aerial parts of New Zealand spinach, .

Twenty compounds, including a new lignan amide, were isolated from the aerial parts of New Zealand spinach, (Pall.) Kuntze, which is an edible halophyte. These compounds were identified by mass spectrometry and nuclear magnetic resonance experiments to be -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, - and -coumaroyl-β-d-glucopyranosides, - and -feruloyl-β-d-glucopyranosides, caffeic acid, staphylionoside E, canabiside D, apocyanol A, megastima-5,7-diene-3,4,9-triol, 1--oleoyl-3--β-d-galactopyranosyl--glycerol, 5,5'-dimethyl-lariciresinol, and kaempferol 3--β-d-glucopyranoside. These compounds were identified in New Zealand spinach for the first time.
