[Chemical constituents from whole plants of Aconitum tanguticum (III)]

Nineteen compounds were isolated from the whole plants of Aconitum tanguticum by various of chromatographic techniques and their structures were determined through spectral analysis (1D, 2D-NMR and MS) and comparison with the literature data. These compounds were identified as 5-hydroxymethy furfural (1), 5-acetoxymethyl furfural (2), pyrrolezanthine [5-hydroxymethyl-1-[2-(4-hydroxyphenyl) -ethyl] -1H-pyrrole-2-carbaldehyde] (3), lichiol B (4), phthalic acid dibutyl ester (5), 3, 4-dihydroxy phenylethanol (6), 3, 4-dihydroxy phenylethanol glucoside (7), salidroside (8), p-hydroxy phenylethanol (9), p-hydroxybenzoie acid glucoside (10), p-hydroxybenzoic acid (11), gastrodin (12), 1-(3, 4-dimethoxyphenyl) -1, 2-ethanediol (13), p-hydroxy benzaldehyde (14), p-hydroxy acetophenone (15), 3, 4-dihydroxy phenyl ethyl acetate (16), syringic aldehyde (17), ethyl beta-D-fructopyranoside (18), and p-hydroxybenzoic acid methyl ester (19). Compounds 3 and 4 were isolated from the Ranunculaceae family for the first time, and compounds 2, 6 and 9-19 were isolated from the Aconitum genus for the first time, and compounds 1 and 5 were isolated from the species for the first time.
