Mammea americana L. - Calophyllaceae - abricó (span.), mamey apple, mammee apple, abrico, Mammiapfel

Evergreen tree, native to the Caribbean and tropical South America, cultivated and naturalized in Central America and elsewhere.

„Mammea americana is often confused with the unrelated but similar looking mamey sapote tree (Pouteria sapota), whose fruit is also called mammee or mamey.“ http://en.wikipedia.org/wiki/Mammea_americana

„The fruit are large, ranging in size from 600 to 2000 g or more, with a thick brown leathery skin, a deep yellow to orange flesh and from 1 to 4 seeds. The flesh is firm and without fiber and often contains the leathery or woody vestiges of aborted seeds embedded in the flesh. The flesh typically adheres to the large seeds, which may weigh on average 70 g or more.“

„β-Ionone (22%), 2-methylbutyric acid (12.5%), E-farnesol (4.6%), and nerolidol (3.8%) were identified by gas chromatography and gas chromatography-mass spectrometry as the major constituents of the volatile fraction of the fresh fruit of mammee apple…“

„The volatile constituents of mammee apple (Mammea americana) fruit pulp obtained by liquid-liquid extraction were analyzed by capillary GC and capillary GC-MS. In total, 51 components (40 of which are identified for the first time in mammee apple) were identified with methyl 3-hydroxy-2(S)-methyl propanoate pure enantiomer and 2-methyl butanoic acid with ee 98.5% S being the major components. Glycosidically bound aroma compounds were identified by capillary GC and capillary GC-MS after isolation of the glycosidic fraction obtained by Amberlite XAD-2 adsorption and methanol elution followed by hydrolysis with a commercial pectinase enzyme. In total 19 bound aroma compounds (aglycones) were identified. These aglycones mainly consisted of carboxylic acids and C13-norisoprenoids of which 2-methyl butanoic acid, 4-hydroxy-β-ionone and 4-oxo-β-ionol are the most representative. Additionally, with the aid of capillary GC-MS (EI and NCI) of trifluoroacetylated derivatives we identified eight glucosides: glucopyranosyl methylbutanoate (two isomers), glucopyranosyl methylbutenoate (two isomers), methyl 3-O-β-D-glucopyranosyl 2-methylpropanoate, methyl 3-O-β-D-glucopyranosyl 2-methylbutanoate, 4-oxo-β-ionyl 9-O-β-D-glucopyranoside and 4-oxo-7,8-dihydro-β-ionyl 9-O-β-D-glucopyranoside.“
