Analysis of the volatile constituents of black chokeberry (Aronia melanocarpa Ell.)

The volatile constituents of black chokeberry were analysed by gas chromatography and mass spectrometry. Concentrations of the 48 compounds identified were in general below their individual threshold values. The main compounds were benzaldehyde cyanohydrin, hydrocyanic acid and benzaldehyde. Among other benzene derivatives identified in the press juice were benzylalcohol, 2‐phenylethanol, phenylacetaldehyde, salicylaldehyde, acetophenone, 2′‐hydroxyacetophenone, 4′‐methoxyacetophenone, phenol, 2‐methoxyphenol and methyl benzoate.
