Summary

The volatile acids extracted by pentane/dichloromethane (2 + 1) from tropical fruit pulps were identified and determined by capillary gas chromatography (HRGC) and combined capillary gas chromatography-mass spectrometry using EI- and CI mode (HRGC-EI/CIMS). In cherimoya (A. cherimolia, Mill.) fruit pulp 47 acids were characterized; major compounds were hexanoic (3 mg/kg) and octanoic (1 mg/kg) acid. Fiftyone acids were identified in guava (P. guajava, L.), 54 in mango (M, indica, L., var. Alphonso) and 56 in papaya (C. papaya, L.). (E)-cinnamoic acid (0.4 mg/kg) and (Z)-3-hexanoic acid (0.2 mg/kg) were determined as major constituents in guava; in mango 5-hydroxy-(Z)-7-decenoic acid (2 mg/kg) and 3-hydroxyoctanoic acid (1.1 mg/kg) and in papaya pulp butanoic acid (1.2 mg/kg) were established as major constituents.

Zusammenfassung

Die extraktiv (Pentan/Dichlormethan, 2 + 1) erfaßbaren flüchtigen Säuren in Fruchtpulpen von Tropenfrüchten sind mittels Capillargaschromatographie (HRGC) und Capillargaschromatographie-Massenspektrometrie (HRGC-EI/CIMS) identifiziert und bestimmt worden. In Cherimoya (A. cherimolia, Mill.)-Fruchtpulpe konnten 47 Säuren charakterisiert werden; Hauptkomponenten waren Hexan- (3 mg/kg) und Octansäure (1 mg/kg). In Guava (P. guajava, L.) sind 51, in Mango (M. indica, L., var. Alphonso) 54 und in Papaya (C. papaya, L.) 56 Säuren identifiziert worden. Als Hauptkomponenten wurden (E)-Zimtsäure (0,4 mg/kg) und (Z)-3-Hexensäure (0,2 mg/kg) in Guava, 5-Hydroxy-(Z)-7-decensäure (2 mg/kg) und 3-Hydroxyoctansäure (1,1 mg/kg) in Mango sowie Butansäure (1,2 mg/kg) in Papaya bestimmt.
