Four new glycoside compounds from Sinapis alba L. and their cytotoxic activity

Four novel compounds, 4-hydroxybenzyl-7-S-β-glucopyranoside (1), 4-hydroxybenzyl-7-S-S-β-glucopyranoside (2), 1-S-(4'-hydroxybenzyl)-6-(4''-hydroxybenzoyl)-β-glucopyranoside (3), and 1-O-(4'-hydroxybenzoyl)-2-O-Z-sinapoyl-β-glucopyranoside (4) were used to isolate from Sinapis alba L. seeds. The structures were accomplished through spectroscopic analysis (NMR and MS) corroborated by chemical studies. Three human cancer cell lines were employed to detect the cytotoxic effects of the compounds.
