The allergens of Dendropanax trifidus Makino and Fatsia japonica Decne. et Planch. and evaluation of cross-reactions with other plants of the Araliaceae family.[Pubmed:10208509]
Contact Dermatitis. 1999 Apr;40(4):209-13.
cis-9,17-Octadecadiene-12,14-diyne-1,16-diol (I), an analog of falcarinol has been identified in our previous report as an active component of Dendropanax trifidus and a strong sensitizer. In this report, 16-hydroxy-cis-9,17-octadecadiene-12,14-diynoic acid (II) and cis-9,trans-16-octadecadiene-12,14-diynoic acid (III) were elucidated as 2 other active components of the plant. Compound I, however, presented with the highest concentration and showed a stronger reaction on patch testing. The leaves of Fatsia japonica Decne. et Planch. were also found to contain compound I, but the amount was found to be 7x more in Dendropanax trifidus than in Fatsia japonica. 5 subjects with hypersensitivity to Dendropanax trifidus and compound I showed positive reactions when patch tested with the leaves of Hedera helix L. and Schefflera arboricola. 1 of these also showed a positive reaction to the extract of Panax ginseng root powder diluted 1% in ethanol. There was cross-reaction among these plants, which all belong to the Araliaceae family.
The major allergen of Dendropanax trifidus Makino.[Pubmed:9197960]
Contact Dermatitis. 1997 May;36(5):252-5.
Dendropanax trifidus Makino (family Araliaceae, syn. Gilibertia trifida Makino) has been reported as causing allergic contact dermatitis in Japan. To identify the major allergen, fractionated extracts of fresh leaves of Dendropanax trifidus were patch tested on 2 patients with hypersensitivity to the plant. Cis-9,17-octadecadiene-12,14-diyne-1, 16-diol (I), an analog of falcarinol, was identified as an active component. 18 normal control subjects were patch tested with the leaf of Dendropanax trifidus and I diluted to 0.05% in pet. 4 of them showed active sensitization to the leaf of Dendropanax trifidus and I. Our results suggest that I is the major allergen of Dendropanax trifidus and is a strong sensitizer. The results of patch testing on patients and control subjects with the leaves of Fatsia japonica Decne. et Planch. and Hedera helix L., which also belong to the Araliaceae family, and urushiol are also shown.
