Summary: Phytochemical investigations on the methanolic extract of Launaea intybacea yielded eleven compounds namely, octadecyl (E)-p-coumarate (1), 4-hydroxy-3- methoxybenzaldehyde (2), 4-hydroxybenzoic acid (3), 4-hydroxy-3-methoxybenzoic acid (4), coumaric acid (5), methyl gallate (6), 3,4-dihydroxybenzoic acid (7), 4',5,7- trihydroxyflavone (8), 3',4',5,7-tetrahydroxyflavone (9), 3,3',5,7-tetrahydroxy-4'- methoxyflavone (10) and apigenin 7-O-(4''-O-p-E-coumaroyl)-(Beta)-D-glucopyranoside (11).
Six fractions (1-6) were obtained which on gradient elution using pure DCM yielded octadecyl (E)-p-coumarate (1); 1%MeOH/DCM yielded 4-hydroxy-3- methoxybenzaldehyde (2), 2% MeOH/DCM afforded 4-hydroxybenzoic acid (3), and 4-hydroxy-3- methoxybenzoic acid (4) from head and tail fractions, respectively; 3% MeOH/DCM provided coumaric acid (5); 4% MeOH/DCM yielded methyl gallate (6); 5% MeOH/DCM afforded 3,4-dihydroxybenzoic acid (7); 6% MeOH/DCM 4',5,7-trihydroxyflavone (8); 7 % MeOH/DCM provided 3',4',5,7-tetrahydroxy- flavone (9); 10 % MeOH/DCM afforded 3,3',5,7- tetrahydroxy-4'-methoxyflavone (10) and 12 % MeOH/DCM yielded apigenin 7-O-(4''-O-p-E- coumaroyl)-(Beta)-D-glucopyranoside (11), respectively.
