Contrary to the mushroom samples, more polyphenols were detected and at higher concentrations in the moringa leaves. A total of 244 features were detected, and the main classes were again flavanones (24%), hydroxycinnamic acids (20%), hydroxybenzoic acids (13%), flavones (10%), and flavonols (10%). Moreover, 55% of the features detected in moringa leaves were conjugated with a glycone. Contrary to all the other samples, the untargeted analysis of moringa leaves did not show any isomers of hesperetin-O-glucoside in the top five features, by both chromatographic peak area and relative quantification, rather phenolic acids predominated (Table .11). Similar to the mushroom samples, the targeted LC-MS/MS measurements revealed that phenolic acids were prevalent in moringa leaves, but it also showed high concentrations of flavonols including rutin at 640 µg/g of dry weight .
