Abstract:
To detect the type of contact dermatitis caused due to the handling of Alstroemeria wilhelmina, 1% α-methylene-γ-butyrolactone (α-MBL) dissolved in physiological saline and a five-fold diluted saline solution of original extracts of flowers, leaves and stems of the flower were applied to guinea-pigs for induction treatment, and 0.1% α-MBL physiological saline and a ten-fold diluted solution of the original extracts were applied to the animals as the challenge treatment in compliance with the guinea-pig maximization test (GMT). As a consequence, not only primary irritant dermatitis was observed, but also delayed type allergic contact dermatitis due to Alstroemeria wilhelmina was observed. α-MBL determined in the extracts using high-performance liquid chromatography (HPLC) was found to be the biochemical material cause of the contact dermatitis. The flower region contained α-MBL in the highest concentrations compared with those of the leaves and stems. Therefore, the quantification of α-MBL in the extracts was concluded as being a useful evaluating method for contact dermatitis due to the handling of Alstroemeria.
