Hot pepper fruits (Capsicum annuum L.) var. Bronowicka Ostra have been studied with regard to content of flavonoids and other phenolics. Nine compounds were isolated from pericarp of pepper fruits by preparative HPLC. Their structures were identified by chromatographic (analytical HPLC) and spectroscopic (UV, NMR) techniques. Two of the identified compounds, trans-p-ferulylalcohol-4-O-(6-(2-methyl-3-hydroxypropionyl) glucopyranoside and luteolin-7-O-(2-apiofuranosyl-4-glucopyranosyl-6-malonyl)-glucopyranoside were found for the first time in the plant kingdom. Additionally compounds: trans-p-feruloyl-β-d-glucopyranoside, trans-p-sinapoyl-β- d-glucopyranoside, quercetin 3-O-α-l-rhamnopyranoside-7-O-β-d-glucopyranoside, luteolin 6-C-β-d-glucopyranoside-8-C-α-l-arabinopyranoside, apigenin 6-C-β-d-glucopyranoside-8-C-α-l-arabinopyranoside and luteolin 7-O-[2-(β-d-apiofuranosyl)-β-d …
