The study reports the isolation and structural identification of two new flavonol triglycosidesfrom the methanolic extract of Anthyllis hermanniae, exhibiting the same glycosylation pattern: quercetin 3-O-[α-l-rhamnopyranosyl-(1→2)-α-l-arabinopyranoside]-7-O-α-l-rhamnopyranoside (1) and kaempferol 3-O-[α-l-rhamnopyranosyl-(1→2)-α-l-arabinopyranoside]-7-O-α-l-rhamnopyranoside (2).
