Abstract The most recent guidelines of IUPAC and AOAC recommend the analysis of specific compounds present in antioxidant fractions. For the first time, honey from different provinces of North (Nampula) and Central Mozambique (Sofala, Manica and Zambezia) was analysed considering specific flavonoids and phenolic acid profiles. Seven phenolic acids (chlorogenic, caffeic, ellagic, ferulic, gallic, p-coumaric and sinapic) and eight flavonoids (catechin, chrysin, kaempferol, luteolin, naringenin, pinocembrin, quercetin and rutin) were screened in the samples. Nampula honey had a higher content of most of these compounds and the total antioxidant activity (even reaching up to 40 mg TE/100 g) compared honey from the other provinces. Unlike in other African honeys, luteolin had the greatest impact in the flavonoid content (in some cases up to 72 mg/100 g), representing alone more than 50% of this family. Resulting from a discriminant analysis, specific flavonoids (pinocembrin, kaempferol, rutin and catechin) followed by the chlorogenic phenolic acid were the most important variables that distinguishes Nampula from the other provinces. This work underlines the importance of Mozambiquean honey as a source of natural antioxidants both of which concern the health benefits and its exploitation as a viable and sustainable income for the local population.

基于特定黄酮类化合物和酚酸化合物的莫桑比克蜂蜜抗氧化特性

摘要 IUPAC 和 AOAC 的最新指南建议对抗氧化剂组分中存在的特定化合物进行分析。首次对来自莫桑比克北部（楠普拉）和中部（索法拉、马尼卡和赞比西亚）不同省份的蜂蜜进行了分析，考虑了特定的黄酮类化合物和酚酸特征。在样品中筛选了七种酚酸（绿原、咖啡酸、鞣花、阿魏酸、没食子酸、对香豆酸和芥子油）和八种黄酮类化合物（儿茶素、白杨素、山奈酚、木犀草素、柚皮素、松香素、槲皮素和芦丁）。楠普拉蜂蜜中大多数这些化合物的含量更高，总抗氧化活性（甚至高达 40 毫克 TE/100 克）与其他省份的蜂蜜相比。与其他非洲蜂蜜不同，木犀草素对类黄酮含量的影响最大（在某些情况下高达 72 毫克/100 克），仅占该家族的 50% 以上。根据判别分析，特定的黄酮类化合物（松柏素、山奈酚、芦丁和儿茶素）其次是绿原酚酸，是区分楠普拉与其他省份的最重要变量。这项工作强调了莫桑比克蜂蜜作为天然抗氧化剂来源的重要性，这两者都涉及健康益处及其作为当地人口可行和可持续收入的开发。芦丁和儿茶素），其次是绿原酚酸，是区分楠普拉与其他省份的最重要变量。这项工作强调了莫桑比克蜂蜜作为天然抗氧化剂来源的重要性，这两者都涉及健康益处及其作为当地人口可行和可持续收入的开发。芦丁和儿茶素），其次是绿原酚酸，是区分楠普拉与其他省份的最重要变量。这项工作强调了莫桑比克蜂蜜作为天然抗氧化剂来源的重要性，这两者都涉及健康益处及其作为当地人口可行和可持续收入的开发。
