Authors : Nabila Helmy Shafik, Reham Ezzat Shafek, Helana Naguib Michael
Abstract : Antimicrobial study of Daucus Carota Canopy extracts against bacteria and fungi showed that the ethanolic extract was the most active.  Phytochemical investigation of the active ethanolic extract gave rise to 12 natural flavone compounds including the new C-glycoside; diosmetin 6,8-Di-C-a-L-rhamnopyranoside besides the first isolation of luteolin 8-C-ß-L-arabinopyranoside and luteolin 6,8-Di-C-a-L-rhamnopyranoside from this plant and the rest 9 known compounds including 3 luteolin glycosides, 1 diosmetin glycosides, 2 chrysoeriol glycosides and 3 aglycones. Their structures were established by chromatographic methods, chemical degradation and various spectroscopic data.
