Resumé

The allergen tulipalin A was collected by dynamic headspace technique from cut flowers of 2 Alstroemeria hybrids and quantified and identified by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The amounts of tulipalin A released into the air were correlated with the tulipalin A and the total allergen content (tulipalin A and tuliposides) in the plant tissue, respectively. Tulipalin A was released primarily from the wounded areas, i.e. the stems, although small amounts were also emitted from the undamaged flowers in one of the hybrids. The tulipalin A concentrations in the stems of the Alstroemeria hybrids investigated were 0.06% and 0.13% of fresh weight, respectively, and the amounts directly released from the cut flowers were 0.4 and 2.2 μg (cut flower)-1 h-1, respectively. The content of tulipalin A exceeded that of tuliposides in leaves and flowers of both hybrids, whereas the content of tulipalin A in stems (in % fresh weight) was slightly lower than the content of tuliposides. The possibility that airborne tulipalin A from Alstroemeria could be a source of airborne contact dermatitis is discussed.
