Abstract

Abstract: Three new acyltyramines, N -[2-(4-hydroxyphenyl)ethyl]hentriacontanamide (1 ), N -[2-(4-hydroxyphenyl)ethyl]nonacosanamide (2 ) and N -[2-(4-hydroxyphenyl)ethyl]heneicosanamide (3 ) have been isolated from n -hexane extract of leaves of Anisodus luridus (Solanaceae). Successive extraction of defatted leaves of A. luridus with methanol afforded a residue on removal of solvent under reduced pressure. Residue was partitioned by means of chloroform and n -butanol. Chromatographic resolution of n -BuOH extract afforded six known compounds, apigenin (4 ), luteolin (5 ), quercetin (6 ), quercetin 3- O - α -l -rhamnoside (7 ), kaempferol 3- O - α -rhamnoside (8 ) and quercetin 3- O - α -l -rhamnopyranosyl-(1→6)- β -d -glucopyranoside (9 ). The structures of the isolated compounds were assigned with the help of spectroscopic techniques. This is the first report of isolation of these compounds from this plant. Abstract :
