Multiple studies investigating polyphenols in moringa leaves have been published. For example, 291 polyphenols were previously annotated, of which 39 were anthocyanins . A higher number of anthocyanins was assigned than here (5 analytes), most likely due to the LC conditions used here not being optimized for anthocyanins . In addition, the lower number of anthocyanins detected in the present study could be attributed to the selected extraction temperature, as anthocyanins are more thermolabile than other polyphenol classes . Similar to our work (Table .11), previous research found that moringa leaves contain high concentrations of caffeoylquinic isomers, gallic acid glucoside, and quercetin and kaempferol with sugar moieties .
