Among the oils that contain carbon-carbon double bonds as the functional groups, linseed, tung, corn, cottonseed, rapeseed, and soybean are more widely used as polymeric sources. Linseed oil is extracted from the seeds of the flax plant Linum usitatissimum). The major constituents of linseed oil are a-linolenic acid (60%), linoleic acid (29%), and oleic acid (27%). This composition varies with changes in climatic conditions. On the other hand, tung oil, also called china wood oil, is derived from the seeds or nuts of the trees aleurites fordii and A. montana. The major constituent of tung oil is eleostearic acid (77-82%), whereas the other important components of tung oil are oleic acid (3.5-12.7%) and linoleic acid (8-10%). It is known that the carbon-carbon double bond in oleic acid is at C9, in linoleic acid it is at C6 and C9, and in linolenic acid it is at C3, C6, and C9, whereas eleostearic acid has double bonds at positions C5, C7, and C9.

The seeds of Aleurites fordii, the tung nut (Euphorbiaceae), formerly cultivated in the south central United States, and presently cultivated in Argentina and China produce toxic proteins. There are many references to human poisoning by this plant, as the seed is large and, to many, appears edible. Press cake from the manufacture of tung oil also is toxic and difficult to detoxify. Cocarcinogenic diterpenes have been recently reported from this plant and are undoubtedly responsible for part of the toxic activity (Beutler et al., 1989). Plants of Jatropha curcas and J. mul-tifida, also from the Euphorbiaceae, contain toxic proteins, sometimes called curcin. Both species are planted widely in the tropics.

Aleurites fordii and A. montana are the source of tung oil (China wood oil) which is characterised by its high level of a-eleostearic acid. 

Tung oil, also known as Chinese wood oil, is native to central and Western China. Aleurites Fordii, the commercially most important species of tung oil apparently has very specific soil preferences, due to its being a large consumer of...
