Abstract: | The purification of the MeOH extract from the rhizome of Sparganium stoloniferum Buch.-Hamil. (Sparganiaceae) using column chromatography furnished one new phenylpropanoid glycoside (7) and known phenolic
compounds (1–6, and 8–13). The structural elucidation of 7 was based on 1D- and 2D-NMR spectroscopic data analysis to be β-d-(6-O-trans-feruloyl) fructofuranosyl-α-d-O-glucopyranoside. Compounds 1–6, and 8–13 were elucidated by spectroscopy and confirmed by comparison with reported data; 24-methylenecycloartanol (1), p-hydroxybenzaldehyde (2), ferulic acid (3), p-coumaric acid (4), vanillic acid (5), β-d-(1-O-acetyl-3-O-trans-feruloyl)fructofuranosy-α-d-2′,4′,6′.-O-triacetyglucopyranoisde (6), β-d-(1-O-acetyl-3,6-O-trans-diferuloyl)fructofuranosyl-β-d-2′,4′,6′.-O-triacetylglucopyranoisde (8), hydroxytyrosol acetate (9), hydroxytyrosol (10), isorhamnetin-3-O-rutinoside (11), n-butyl-α-d-fructofuranoside (12), and n-butyl-β-d-fructopyranoside (13). Compounds 3 and 9–13 were isolated for the first time from this plant. The isolated compounds were tested for cytotoxicity against four human
tumor cell lines in vitro using a Sulforhodamin B bioassay. |
