A new flavonoid glycoside from Vaccaria hispanica.
A profiling analysis for the methanol extract of the seeds of Vaccaria hispanica (Mill.) Rauschert was performed using a HPLC-ESI-MS technique. Five compounds were identified according to their retention times, UV spectroscopic and MS features, and by comparison with literature data. Among them, a new flavonoid glycoside, named vaccarin H, was isolated and the structure determined by spectral and chemical analysis as isovitexin 2"-O-alpha-L-arabinopyranosyl-4'-O-(6""-O-dihydroferuloyl)-3-beta-glucopyranoside.
