Abstract

Two sinapic acid esters were isolated from the methanol extract of Raphani Semen. The structures were elucidated on the basis of spectroscopic methods $(^1H-NMR,\;^{13}C-NMR,\;HMQC,\;^1H-^1H\;COSY\;and\;HMBC)$ and were identified as methyl sinapate (1) and ${\beta}-D-(3-O- sinapoyl)fructofuranosyl-{\alpha}-D-(6-O-sinapoyl)glucopyranoside$ (2). Compound 1 was first isolated from the genus of Raphanus.
