Abstract

The purpose of the current study was a qualitative UHPLC-PDA-ESI-MS analysis of phenolic compounds in the aerial parts of Cuphea ingrata, which led to detection of over sixty constituents: tannins, flavonoids, phenolic acids and their derivatives. The presence of oenothein B-type macrocyclic dimeric ellagitannins seems to be of particular importance. Quercetin sulfate, that has been previously identified as characteristic chemotaxonomic marker in Cuphea carthagenensis, was found in C. ingrata, as well.

摘要

本研究的目的是对Cuphea ingrata地上部分的酚类化合物进行定性 UHPLC-PDA-ESI-MS 分析，从而检测出超过 60 种成分：单宁、类黄酮、酚酸及其衍生物。月见草苷 B 型大环二聚鞣花单宁的存在似乎特别重要。硫酸槲皮素，之前已被确定为Cuphea carthagenensis的特征化学分类标记，也在C. ingrata中发现。
