Abstract
DOI: 10.1002/jssc.202000962 The cover picture shows Ribes meyeri leaves, a traditional Kazakh medicine in China. Liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry was used to analyze the phenolic components of Ribes meyeri leaves. We identified 77 phenolics by comparing retention times, accurate masses, fragmentation patterns, and literature data. Ultra-high performance liquid chromatography coupled with triple quadrupole mass spectrometry was applied to simultaneously quantify 12 phenolics in R. meyeri leaves. Rutin, epigallocatechin, isoquercitrin, epicatechin, protocatechuic acid, and kaempferol-3-O-rutinoside were abundant in the R. meyeri leaves.
