Polymethoxylated flavones from citrus reticulata blanco cuv baladi

ABSTRACT

The new 3,5,6,8,4'-pentamethoxy [1] and 3,5,6,8,3',4'-hexamethoxy [2] flavones were isolated from Citrus reticulata leaf, beside beta- sitosterol and 5-O-desmethyl nobilletin. Structure elucidation of the two compounds was achieved through UV, 1H-NMR, 13C-NMR and 1H-13CNMR analyses
