Toxicodendron radicans dermatitis with black lacquer deposit on the skin

Journal of the American Academy of Dermatology, 1982
Four patients with clinical Toxicodendron dermatitis (poison ivy) presented with dramatic black lacquer-like deposits on several lesions. This black deposit was also observed at sites of injury on poison ivy plants and was reproduced on volunteers by the application of plant sap on the skin.

Catecholic and other constituents of the leaves of Toxicodendron radicans and variation of urushiol concentrations within one plant

Phytochemistry, 1980
Abstract Extracts of T. radicans were prepared for GC-MS by ethanol extraction of individual leaves followed by silylation. Analyses for the urushiol components were performed by monitoring ions at m/e 179 and the molecular ions of the various olefins.

New GLC Analysis of Urushiol Congeners in Different Plant Parts of Poison Ivy, Toxicodendron radicans

Journal of Pharmaceutical Sciences, 1978
Methods are presented for the direct GLC analysis of the catechol C15 alkenyl side-chain congeners contained in the urushiol fraction of poison ivy (Toxicodendron radicans) and the C17 homologs of poison oak (Toxicodendron diversilobum). A number of liquid phases were investigated and demonstrated varying degrees of separation.

Poison Ivy (Toxicodendron radican) Control with Triclopyr and Metsulfuron, Applied Alone and in Tank Mixture

Weed Technology, 2013
Dermatitis from poison ivy is an important health problem, and considerable effort is devoted to the control of this virulent weed. Triclopyr, metsulfuron, and two fixed-ratio tank mixtures of triclopyr and metsulfuron were evaluated across a series of rates for poison ivy control. The objective was to test whether tank mixtures are more effective than

Rising Atmospheric Carbon Dioxide and Potential Impacts on the Growth and Toxicity of Poison Ivy (Toxicodendron radicans)

Weed Science, 2007
Because of its ability to induce contact dermatitis, the establishment and spread of poison ivy is recognized as a significant public health concern. In the current study, we quantified potential changes in the biomass and urushiol content of poison ivy as a function of incremental changes in global atmospheric carbon dioxide concentration (CO2).
