Anthraquinones and xanthones are also important constituents of many lichens. Anthraquinmies such as parietin, parietinic acid, emodin, fallacinol, and fallacinal were shown to have a high antimicrobial effect (Manojlovic et al. 2002). Manojlovic et al. (2010) found that the antimicrobial activity of Uchen Laurera benguelensis is mainly related to the presence of Uchexanthone. [Pg.85]

Lichens have proven a useful source of antiviral agents. Established antiviral properties have been attributed to some specific lichen secondary metabolites including usnic acid, parietin, anthraquinones, hypericin, lichenan, etc. For instance, lichenan, which is widely distributed in lichens, is demonstrated to inhibit the tobacco mosaic vims (Stubler and Buchenauer 1996).

In addition to emodins, rhubarb root also contains dimeric reduced forms of emodins derived from 10,10 -bianthronyl (9-167), which are called bianthrones (dianthraquinones). They can occur as homobianthrones, such as emodin bianthrone and parietin bianthrone, or as heterobianthrones (mixed dimers), such as pahnidin A (9-168), which is bianthrone of emodin and aloe-emodin.
