Introduction:
Usnic acid is a naturally occurring dibenzofuran derivative found in several lichen species. It was first
isolated by German scientist W. Knop in 1844 and first synthesized between 1933-1937 by Curd and
Robertson. Usnic acid was identified in many genera of lichens including Usnea, Cladonia, Lecanora,
Ramalina, Evernia, Parmelia and Alectoria. Although it is generally believed that usnic acid is exclusively
restricted to lichens, in a few unconfirmed isolated cases the compound was found in kombucha tea
and non-lichenized ascomycetes.
At normal conditions, usnic acid is a bitter, yellow, solid substance. It is known to occur in nature in
both the d- and l-forms as well as a racemic mixture.
Lichen extracts containing usnic acid have been utilized in medicine, perfumery, cosmetics, and ecology.
Usnic acid possesses a wide range of interesting biological properties. It is a potent antibiotic effective
against Gram-positive bacteria, including Staphylococcus, Streptococcus, and Pneumococcus, other
bacteria such as Mycobacterium tuberculosis, and some pathogenic fungi. It also exhibits antiviral,
antiprotozoal, antimitotic, anti-inflammatory and analgesic activity. Other characteristics, like ultraviolet
absorption, preserving properties, antigrowth, antiherbivore and anti-insect properties, have also been
demonstrated.
Usnic acid has been included as an ingredient in creams, powders, toothpastes, mouthwash, deodorants,
hair shampoos and sunscreen products.
