IDENTIFICATION AND QUANTIFICATION OF THE ALLERGENS (TULIPOSIDES AND TULIPALIN A) IN ALSTROEMERIA |
| Authors: | Lars P. Christensen, K. Kristiansen |
| Abstract:
From aqueous extracts of leaves, stems and flowers of several Alstroemeria species and hybrids the content of the allergenic tuliposides and tulipalin A were determined by isocratic Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC). The allergens were found in all genotypes investigated, although in very different amounts. Also a large genotypic variation was found in some species and hybrids, with respect to the content of tuliposides. The highest concentrations of tuliposides were found in stems and flowers, whereas tulipalin A is mainly present in flowers. The possibility to breed new Alstroemeria cultivars which are less allergenic than the common cultivars is discussed. | |
