Phytochemical and chemotaxonomic investigation from the roots of Anemone vitifolia Buch.-Ham. (Ranunculaceae)

Abstract

Phytochemical investigation from the roots of Anemone vitifolia Buch.-Ham. led to the isolation of eight compounds, including one triterpenoid saponin, two sugars, one coumarin, one amide, one saturated alkane, one olefin and one fatty acid. The structures of these metabolites were elucidated by spectroscopic data and comparisons with the data available in the literature. Among them, compound 7 ((6Z,9Z,12Z)-6,9,12-Eicosatriene) was isolated for the first time as a natural product. Furthermore, compounds 2 (D-(+)-raffinose), 3 (mixture of β-D-fructopyranose and β-D-fructofuranose) and 5 (bonaroside) were obtained from the Ranunculaceae family for the first time. Compounds 4 (siderin) and 6 (n-hexadecane) were isolated from A. vitifolia for the first time. The chemotaxonomic significance of the isolated compounds was discussed.
