Seven new flavonoids, named : 7-O- ( α - ramnopyranosyl- (1-6) - β -glycopyranosyl) - 3 (3'', 4'' dimethyl-3'' pentényl) 4', 5-dihydroxy flavones ( 1 ) , the second compound 4' - methoxyisoflavone 7-O- β -glycopyranoside ( 2 ), 6- C- β - (2'' - O β – gluco-pyranosyl-glucopyranosyl) - 5,7,4' - trihy droxy flavones ( 3 ) , the fourth compound 5-hydroxy 3', 4' – methoxyisoflavone ( 4 ) , 5,4' - diméthoxy-3,6-dihydroxy flavonol( 5 ), 3-hydroxy-5,6,7,4' – tetra- Methoxyflavone ( 6 ) , 7,8- (2''', 2''' – di-Methylchromeno) -6-prenyl -3,5,4'-trihydroxy-flavone ( 7 ) were isolated from aerial parts of Limoniastrum feei, The structures w ere determined on basis of spectroscopic methods.
