Flower volatiles from 4 raspberry (Rubus idaeus) cultivars (Glen Prosen, Glen Moy, Malling Orion, and Glen Clova), and wild hawthorn (Crataegus monogyna) were entrained on the porous polymers, Haysep Q and Tenax TA, and analysed by GC-MS. The major classes of compound identified included aliphatic and aromatic aldehydes, ketones, alcohols, esters, monoterpenes, sesquiterpenes, and a number of unusual nitrogen compounds (data tabulated). The volatile profiles of the flowers of the 4 raspberry cultivars exhibited only minor differences, and the main constituent was identified as trans-β-ocimene. Volatiles from the flowers of hawthorn, although similar in many respects, contained proportionately lower levels of terpenoids, but elevated levels of benzaldehyde, 3-methyl-1-butanol, 4-methoxybenzaldehyde, 3-pyridine carboxaldehyde, and 4-methoxybenzoic acid methyl ester.
