Several members of the family are known to possess beneficial properties which positively impact human diet, thanks to the presence of antioxidants, bioactive polyphenols and amino acids. , one of the most widespread and economically relevant species, represents an outstanding example. The aim of this study is to investigate, at the molecular level, the effect of plant aging on the concentration of some biologically relevant compounds in different parts of the plant. Using HPLC and NMR techniques, the quantification of polyphenolic species (caffeic acid, quercetin and rutin), succinic acid and alanine was performed in flowers and leaves of young and mature plants.
几种该属植物被认为具有有益特性，能够通过抗氧化剂、生物活性多酚和氨基酸积极影响人类饮食。作为最广泛和经济上最相关的物种之一， 就是一个极好的例子。本研究旨在从分子水平上研究植物衰老对植物不同部位一些生物相关化合物浓度的影响。使用高效液相色谱法和核磁共振技术，对幼龄和成熟 植物的花和叶中的多酚类物质（咖啡酸、槲皮素和芦丁）、琥珀酸和丙氨酸进行了定量分析。
