description
The genus Rhus includes several species, some of which are poisonous and the others have medicinal and economic values.
The chemical nature of the poisonous principles in poison oak (Rhus diversiloba) (Hartman and Offord, 1947), as well as the medicinal and other applications, chemical constituents and bioactivities of Chinese Rhus species (Zhao et al., 2006) were reviewed.
The main constituents of these plants are phenolic compounds (flavonoids, long-chain phenols, tannins, and lignans) and triterpenes.
From the roots of Rhus javanica L. var. roxburghiana, thirty-seven compounds have been isolated and identified.
These compounds were 15 triterpenoids, 5 steroids, 2 lignans, 2 flavonoids, 9 phenolics and 4 other aromatic compounds (Lee et al., 2005). Examples of these compounds are mentioned below.

Rhus chinensis has long been used by folk medicine practioners in Asia. Leaves, roots, stem, bark, fruit and particularly the galls on the leaves are recognized to have preventive and therapeutic effects on different ailments (such as diarrhea, dysentery, rectal and intestinal cancer, diabetes mellitus, sepsis, oral diseases and inflammation) (Djakpo and Yao, 2010).
