| 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. |
