Volatile carbonyl compounds of arctic brambles at various stages of ripeness were analyzed as their 2,4-DNPH's by a combined TLC-GLC-MS method. Twenty-one different carbonyl compounds could be identified. During the ripening process the content of most carbonyl compounds increased, the largest changes occuring in the amounts of acetaldehyde, pentenal, acetone, acetonn and diacetyl but the content of hexenal decreased.
