Abstract
There is an emerging interest in plant polyphenols as dietary ingredients, particularly for
digestive disorders and/or as antitumor agents. The plant compounds or extracts continue to be an
alternative to drug use, and many studies aim to find natural substances with selective cytotoxicity
on abnormal cells. Phenolic compounds, as important secondary metabolites from plants, are intensively
studied as a substitute for drugs. In this review, the recent literature data from the past five
years about the potential anticancer/antitumor effect of some categories of phenolics such as stilbenes
and xanthones extracted from medicinal plants were surveyed. The most important results
concerning the effectiveness of these active compounds as antitumor/anticancer agents, isolated
compounds or as plant extracts, some bioavailability aspects and their mechanism of action in vitro
and in vivo, were considered.
Keywords:
Stilbenes, xanthones, medicinal plants, cytotoxicity, antitumor/anticancer effect, bioavailability.
