Annona cherimola Mill. - syn.Annona pubescens Salisb.; Annona tripetala Aiton - Annonaceae
cherimoya, custard-apple, Cherimoya
Evergreen tree, up to 9m high. „Widely cultivated now, Annona cherimola is believed to originate from the Andes at altitudes of 700m to 2,400m although an alternate hypothesis postulates Central America as the origin of Annona cherimola because many of its wild relatives occur in this area. From there it was taken by Europeans to various parts of the tropics. Unlike other Annona species, A. cherimola has not successfully naturalized in West Africa, and in Australasia Annona glabra is often misidentified as this species.“

„The major compounds identified in the four cherimoya cultivars were methyl butanoate, butyl butanoate, 3-methylbutyl butanoate, 3-methylbutyl 3-methylbutanoate and 5-hydroxymethyl-2-furfural. These compounds represent 69.08 ± 5.22%, 56.56 ± 15.36%, 56.69 ± 9.28% and 71.82 ± 1.29% of the total volatiles for Funchal, Madeira, Mateus and Perry Vidal cultivars, respectively. This study showed that each cherimoya cultivars have 40 common compounds, corresponding to different chemical families, namely terpenes, esters, alcohols, fatty acids and carbonyl compounds…“
