Abstract

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-beta-D-glucopyranoside, trans-p-sinapoyl-beta- D-glucopyranoside, quercetin 3-O-alpha-L-rhamnopyranoside-7-O-beta-D-glucopyranoside, luteolin 6-C-beta-D-glucopyranoside-8-C-alpha-L-arabinopyranoside, apigenin 6-C-beta-D-glucopyranoside-8-C-alpha-L-arabinopyranoside and luteolin 7-O-[2-(beta-D-apiofuranosyl)-beta-D-glucopyranoside] were found for the first time in pepper fruit Capsicum annuum L.

摘要

对辣椒果实（辣椒属）品种Bronowicka Ostra的类黄酮和其他酚类物质含量进行了研究。通过制备型高效液相色谱法从辣椒果实的果皮中分离出9种化合物。通过色谱法（分析型高效液相色谱）和光谱法（紫外、核磁共振）技术鉴定了它们的结构。在植物界首次发现了两种已鉴定的化合物，反式对香豆醇-4-O-(6-(2-甲基-3-羟基丙酰基)吡喃葡萄糖苷和木犀草素-7-O-(2-芹菜呋喃糖基-4-吡喃葡萄糖基-6-丙二酰基)-吡喃葡萄糖苷。此外，在辣椒果实辣椒属中首次发现了以下化合物：反式对香豆酰基-β-D-吡喃葡萄糖苷、反式芥子酰基-β-D-吡喃葡萄糖苷、槲皮素3-O-α-L-鼠李糖吡喃糖苷-7-O-β-D-吡喃葡萄糖苷、木犀草素6-C-β-D-吡喃葡萄糖苷-8-C-α-L-阿拉伯糖吡喃糖苷、芹菜素6-C-β-D-吡喃葡萄糖苷-8-C-α-L-阿拉伯糖吡喃糖苷和木犀草素7-O-[2-(β-D-芹菜呋喃糖基)-β-D-吡喃葡萄糖苷]。
