-The volatiles from a pentane extract of fruits (pectinase treated) were analyzed by GC. Main constituents were aromatic compounds with benzyl alcohol (40.2%), benzaldehyde (3.2%), methyl benzoate (1.5%), acetophenone (1.1%), styrene (1%), and eugenol (1%). Aliphatic alcohols and aldehydes included 1-pentanol, 1-hexanol, 2-methyl 3-butenole, (Z)-3-hexenol as well well pentanal, hexanal, nonanal and (E,E)-2,4-decadienal e.g.; terpenes α-pinene, β-pinene, 4-terpineol and α-terpineol e.g. Main fruit ester was ethyl acetate (4.1%).\\

 "Of the remaining compounds, 2-methyl butyric acid is no doubt the most important one. It is almost as abundant as benzyl alcohol and it has as related aliphatic acids also a high specific odour intensity. Its contribution to the aroma of lingonberries is obvious from the fact that the typical lingon aroma disappears from the pentane extract on neutralization." \\

+"Juice of lingonberries... was analysed for volatile compounds... 2-methyl butyric acid amounting to 48% of the concentrate and the aromatic compounds are likely to be the most important ones for lingonberry aroma." \\
