摘要: 从全国5个荞麦种植区域中各选取一种甜荞和苦荞,采用反向液相色谱法(RP-HPLC)分析甜荞和苦荞麸皮中8种酚酸、3种黄酮的含量差异。结果表明:同一种植区域不同种类和同一种类不同种植区域的荞麦麸中酚类物质含量存在显著差异。其中,苦荞的自由态酚酸、总酚酸、自由态黄酮和总黄酮含量均高于同一种植区域的甜荞。此外,甜、苦荞中均含有没食子酸、原儿茶酸、香草酸、咖啡酸、p-香豆酸、阿魏酸、儿茶素、芦丁及槲皮素,其中苦荞中对羟基苯甲酸含量丰富。

Abstract: Phenolic components including 11 phenolic acids and 3 flavonoids in common and tartary buckwheat varieties from different geographical regions were analyzed by high performance liquid chromatography (HPLC). The results showed that a significant difference in the content of phenolic components was observed between common and tartary buckwheat varieties cultivated in same geographical regions. Similar results were also observed in same buckwheat variety cultivated in different geographical regions. Meanwhile, the contents of free phenolic acids and flavones in tartary buckwheat were higher than that of common buckwheats. In addition, common and tartary buckwheat varieties contained gallic acid, protocatechuic acid, vanillic acid, caffeic acid, p-cumaric acid, ferulic acid, catechin, rutin and quercetin. Moreover, tartary buckwheat was rich in p-hydroxybenzoic acid.

Key words: common buckwheat, tartary buckwheat, high performance liquid chromatography (HPLC)phenolic acids, flavones
