Usnic acid is found in oak moss and used in perfumes. Usnea barbata is a lichen species that occurs in oak moss. Cross-reactions between structurally related lichen compounds are unclear, but must be considered (Mitchell 1965 Hausen et al. 1993). Contact dermatitis in vaginal ovules and contact allergy in deodorant spray has been reported (Hein and Tarnick 1987 Rafanelli et al. 1995). The patch-test concentration is 0.1% pet. Allergic reactions are rare or uncommon. [Pg.464]

C, pressure 350bar, time 6h, flow rate 20kg CO2 per h for the extraction of usnic acid from Usnea barbata. For microscale extraction, acetone is recommended, as most lichen substances are soluble in this solvent. The use of the microextractor shown in the monograph of Asahina and Shibata (1954) cannot be recommended because of the risk of inflammation of the solvent. A simple and safe device is shown in Fig. 4. [Pg.11]

In the study described by Rankovic et al. (2012), lichen compounds, norstictic acid isolated from Toninia Candida and usnic acid from Usnea barbata, exhibited high antioxidant potential in vitro, but it should be noted that the norstictic acid had a larger antioxidant capacity. [Pg.121]

Various other propagules have been described in lichens and are discussed in detail in Chapters 1 and 3. Most of these, as Barkman (1958) indicates, are the heavier type of vegetative diaspore and, while probably removed by wind, are subsequently carried only short distances. An early example is found in von Schrenk (1898), who recorded dispersal of thallus fragments of Usnea barbata and pointed out that pendulous forms of Usnea rarely produce apothecia. [Pg.119]
