Other plant constituents, such as methylxanthines, thiourea, tannins, coumarin, parasorbic acid, safrole, estragole, and eugenol, and plant estrogens, such as zearalenone, are carcinogenic in laboratory animals and/or mutagenic in bacterial or mammalian cell systems.

2018年6月7日 · 99.99% (by weight) of the pesticides consumed by the American public are made by the plants themselves as a defense mechanism. Synthetic and natural pesticides are equally likely to be carcinogenic. (You are unlikely to see this information posted in a Whole Foods.)

Ptaquiloside is the primary carcinogenic component in bracken fern and when activated to a dienone (APT or activated ptaquiloside), forms DNA adducts and eventually leads to tumor development. It is the only known plant carcinogen that causes natural outbreaks of bladder and/or intestinal cancer in livestock .

According to current knowledge, the limited number of biosynthetic pathways in higher plants produces only a small number of constitutive naturally occurring chemicals found to be carcinogenic in animals.

The EU Council Directive on Flavorings (88:388:EU) regulates intrinsic toxicants from many plant source materials, including plant foods, herbs, and spices, such as coumarin, thujone, safrole, and hydrocyanic acid (originating from cyanogenic glycosides) .

This paper discusses some plants that are used as food or medicine. These plants are known to contain chemical components that have been identified as genotoxic carcinogens. Often contradictory results are obtained with beneficial and adverse effects reported.

Although cancer-causing substances are often thought by the general public to be synthetic, there are numerous carcinogens that occur in nature, and in food plants. (Concon,1988) For example, tannins occur widely in plant foods and we ingest them daily in tea, coffee, and cocoa.

Plants may not only act as accumulators and conduits for environmental carcinogens in the food chain, but can contribute carcinogenic natural products to the human diet

2018年6月1日 · The focus is on ten compound groups and includes examples of potential carcinogens, beneficial uses, adverse effects and relevant plant species. It provides evidence of sophisticated test systems and in vivo models, which can now predict more accurately the adverse effects of chemical constituents.

Some toxic chemicals, especially those produced by microbes and plant cells, exhibit carcinogenic activity. Even though some of these compounds are integral components of foods relatively common in the diet of humans, many of these carcinogens have also been found in...
