INTERNAL POISONING FROM RHUS

Case of Poisoning by Rhus Venenata

On the Active Principle of Rhus Toxicodendron and Rhus Venenata

Of all the cutaneous eruptions caused accidentally by vegetable matters, that produced by the different ]rinds of Rhus is probably the most common in this country. The common occurrence of poisoning with poison ivy and poison sumach, and the lack of any rational treatment for this, led me to try to isolate the active principle of these plants, in the hope that a knowledge of its characteristic ...

New antifungal xanthones from the seeds of Rhus coriaria L.

Phytochemical investigations of the ethanolic extract of the seeds of Rhus coriaria L. (Anacardiaceae) led to the identification of four new xanthones, characterized as 2,3-dihydroxy-7-methyl xanthone (1), 2,3,6-trihydroxy-7-hydroxymethylene xanthone-1-carboxylic acid (2), 2-methoxy-4-hydroxy-7-methyl-3-O-beta-D-glucopyranosyl xanthone-1,8-dicarboxylic acid (4), and 2-hydroxy-7-hydroxymethylene...

Biological activities of extracts from sumac (Rhus spp.): a review.

Sumac is the common name for a genus (Rhus) that contains over 250 individual species of flowering plants in the family Anacardiaceae. These plants are found in temperate and tropical regions worldwide, often grow in areas of marginal agricultural capacity, and have a long history of use by indigenous people for medicinal and other uses.

A new biflavonoid and an isobiflavonoid from Rhus tripartitum.

A new biflavonoid masazinoflavanone (1) and the isobiflavonoid calodenone (2) have been isolated and characterized from the methanolic aerial part extract of the plant Rhus tripartitum. Their structures have been deduced from extensive spectral analysis (NMR and MS). Interpretation of the nuclear overhauser effects (NOESY) permitted us to establish relative stereochemistry of these natural prod...
