Nawwar, Mahmoud A.M.,El-Mousallamy, Amany M.D.,Barakat, Heba H.,Buddrus, Joachim,Linscheid, Michael

, p. 3201 - 3206 (1989)

The new natural lactoyl (2-hydroxypropionyl) flavonoids, luteolin and apigenin 7-lactates together with their 2″-O-β-glucuronides and 2″-O-β-glucosides were isolated from the leaves of Marrubium vulgare. The known flavonoids, vicenin II, vitexin, luteolin 7-glucoside, apigenin 7-glucoside, apigenin 7-(6″-p-coumaroyl)glucoside, luteolin, chrysoeriol and apigenin were also found. The structures were established by conventional methods of analysis and confirmed by 1H, 13C NMR and MS analysis. 2D-chemical shift correlation NMR was applied in the case of the new flavonoids.
