Laurera benguelensis

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.
