Cheritamine, A New N‐Fatty Acyl Tryptamine and Other Constituents from the Stems of Annona cherimola

Abstract A new N ‐fatty acyl tryptamine, cheritamine ( 30 ), along with thirty‐two compounds including nineteen benzenoids, p ‐hydroxybenzadehyde ( 1 ), p ‐hydroxybenzoic acid ( 2 ), methylparabene ( 3 ), 3‐chlorobenzoic acid ( 4 ), vanillin ( 5 ), isovanillin ( 6 ), vanillic acid ( 7 ), isovanillic acid ( 8 ), methyl vanillate ( 9 ), methyl isovanillate ( 10 ), syringaldehyde ( 11 ), syringic acid ( 12 ), 3,4,5‐trimethoxybenzoic acid ( 13 ), trans ‐methyl p ‐coumarate ( 14 ), ferulic acid ( 15 ), p ‐dihydrocoumaric acid ( 16 ), 3‐(4‐hydroxy‐3,5‐dimethoxyphenyl)‐1,2‐propanediol ( 17 ), 3,4,5 ‐trimethoxyphenyl‐β‐D‐glucopyranoside ( 18 ) and thalictoside ( 19 ); one p ‐quinone, 2,6‐dimethoxy‐ p ‐quinone ( 20 ); one purine, uridine ( 21 ); eight alkaloids, nicotinic acid ( 22 ), thalifoline ( 23 ), doryphornine ( 24 ), (–)‐norstephalagine ( 25 ), (‐)‐romucosine ( 26 ), (+)‐pronuciferine ( 27 ), (+)‐norisocorydine ( 28 ) and oxoasimilobine (29) and three steroids, β‐sitosterol‐D‐glucoside ( 31 ), stigmasterol‐D‐glucoside ( 32 ) and 6′‐(β‐sitosteryl‐3‐ O ‐β‐glucopyranosidyl)hexadecanoate ( 33 ), are isolated from the stems of Annona cherimola. These compounds were characterized and identified by physical and spectral evidence.
