Flavonoid glycosides of 18 Plantago species belonging to six sections
were investigated. Twenty-five glycosides were found to belong to the
aglycones apigenin, luteolin, chrysoeriol, tricin and the less common
hispidulin, nepetin and 5,6,7,3'-tetrahydroxy-4'-methoxyflavone. Only
one flavonol glycoside (isorhamnetin 3-rutinoside) was detected in thr
ee species belonging to sect. Leucopsyllium. Chemosystematic relations
hips are discussed.
