Flavonoid glycosides of eight Trigonella species belonging to four sec
tions of the Leguminosae [Gamal El Din, E.M. and Hassan, A.E. (1995) T
aeckholmia, in press] were investigated. Fifteen glycosides were found
based on the aglycones kaempferol, quercetin and the less common 7,4'
-dihydroxyflavone and 7,3',4'-trihydroxyflavone. One isoflavone (formo
nonetin) was found in all Trigonella species. Chemosystematic relation
ships are discussed. (C) 1998 Published by Elsevier Science Ltd. All r
