The volatiles of fresh cherimoya (Annona cherimolia, Mill.) fruit pulp were separated by standard controlled high-vacuum distillation and solvent extraction (pentane-dichloromethane mixture, 2:1). After preseparation by adsorption chromatography on silica gel using a pentane-diethyl ether gradient, the three fractions obtained were analyzed by capillary gas chromatography and combined capillary gas chromatographic techniques, i.e., on-line mass spectrometry and FTIR spectroscopy. In total, 208 volatiles could be identified by these methods. Among them, 23 hydrocarbons, 58 esters, 54 alcohols, 47 carbonyls, and 26 volatiles of miscellaneous structures were found. Quantitatively, alcohols such as 1-butanol, 3-methyl-l-butanol, 1-hexanol, and linalool and a series of butanoates and 3-methylbutyl esters comprised the major part of the volatiles. Among different terpenes, some terpene esters and various bicyclic derivatives were remarkable.

The volatiles of fresh cherimoya (Annona cherimolia, Mill.) fruit pulp were separated by combined high‐vacuum distillationliquid/liquid extraction (pentane/dichloromethane 2+1). After preseparation by liquid chromatography on silica gel three fractions (I‐III) were obtained by eluting with pentane (I), pentane/diethyl ether (9+1) (II), and diethyl ether (III), and fractions II and III were subjected to HRGC/FT‐IR analysis. 26 volatile compounds comprising nearly all the main components (range, 10–300 μg/kg fruit pulp) were identified by this technique for the first time in cherimoya fruit.
