The neutral fraction of medium volatility from raspberry oil has been analysed by gas chromatography and mass spectrometry. From the large number of constituents thirtynine have been identified, 24 of them for the first time, including dihydro-β-ionone (I), epoxy-β-ionone (II), damascenone (III)1, theaspirane (IV) and 2-hexen-4-olide (V). According to these results raspberry oil consists mainly of alcohols, ketones, aldehydes and lactones.
