Abstract This article illustrates the chemical characterization of phenolic compounds, of the selected species of the genus Embelia viz., Embelia ribes, Embelia tsjeriam-cottam, and Embelia basaal using liquid chromatography coupled with mass spectrometry analysis with electrospray ionization (ESI) in negative mode. The analysis of samples allowed first-time identification of different phenolic compounds, which consists of various types of flavonoids, flavonoid glycosides, organic acids, and their derivatives, benzenoids, coumarins, and stilbens in this genus. Seventy-three different phenolic compounds were identified based on the fragment ions, and over thirty unknown compounds with unique fragmentation patterns were further noted. The results of the study offer that the selected species of the genus Embelia, which is being used in centuries-old traditional medical systems, is a promising source of medicinally valuable compounds like luteolin, sinesetin, rutin, naringenin, astragalin, narcissin, vanillic acid, resveratrol, and so on.

液相色谱-质谱联用对三种Embelia属中酚类化合物的初步表征

摘要 本文说明了选择的 Embelia 属的酚类化合物的化学表征，即 Embelia ribes、Embelia tsjeriam-cottam 和 Embelia basaal 使用液相色谱结合质谱分析和电喷雾电离 (ESI) 在负模式下. 样品分析首次鉴定了不同的酚类化合物，包括该属的各种黄酮类化合物、黄酮苷类、有机酸及其衍生物、苯类、香豆素类和芪类。根据碎片离子鉴定了 73 种不同的酚类化合物，并进一步记录了 30 多种具有独特碎片模式的未知化合物。研究结果表明，选定的 Embelia 属物种，
