“…Among other classes of compounds found in lichens of the genus Ramalina , the research of Czeczuga and Ferraro (1987) [123] presents isolated carotenoids of lichens from the Argentinian species R. ecklonii (a) and R. usnea (b) and the review of Dembistsky (1992) [124] features carotenoids of lichens from New Zealand, among them the species R. celastri (c), the isolated compounds were β-cryptoxanthin (a,b) ( 79 ), lutein epoxide (a,b,c) ( 80 ), violaxanthin (a,c) ( 81 ), auroxanthin (a,b) ( 82 ), astaxanthin (b,c) ( 83 ), mutatoxanthin (b) ( 84 ), lycoxanthin (a) ( 85 ), antheroxanthin (a,b) ( 86 ), ε-carotene (b) ( 87 ), zeaxanthin (a,c) ( 88 ), β-carotene (c) ( 89 ), α-doradexanthin (c) ( 90 ), lutein (b,c) ( 91 ), hydroxyechinenone (a) ( 92 ), diatoxanthin (a) ( 93 ), neoxanthin (a,b) ( 94 ) and rhodoxanthin (a,b) ( 95 ) [123,124]. Several of these carotenoids are also found in higher plants, in algae, yeast and other marine organisms [120].…”

Lichens are a form of symbiont between a fungus and an alga or cyanobacterium, which contains a wide variety of organic compounds with certain secondary metabolite classes typical of these organisms. The Ramalina genus has approximately 246 species distributed around the World, of which in this review approximately 118 species with published chemical or biological activity studies of extracts or isolated compounds were cited. From the 153 mentioned compounds, only 27 passed were tested for biological activity, being usnic acid the most studied compound and the one showing the best results in almost all in vitro tests performed, although other compounds also presented excellent results as antimicrobial, antitumor and anti-inflammatory agents, among others. Extracts of several species also presented significant results in performed biological tests, demonstrating the potential that these organisms have, in particular, the gender Ramalina, to produce bioactive molecules that can be used as a model for the production of pharmaceuticals.

“…As regards the carotenoids observed in the present study which are rarely noted in lichens the f'wst, ccarotene, was previously found in Ramalina usnea from Argentina (Czeczuga & Ferraro de Corona 1987). The nextrare carotenoid, Y-epilutein, was fwst reported in thalli of Sticta sylyatica and Peltigera horizontalis collected from Ireland (Czeczuga & Richardson 1989).…”

Column and thin-layer chromatography revealed the presence of the following carotenoids in the thalli of seventeen lichen species from New Zealand: e-carotene, a-carotene, 13-carotene, flcryptoxanthin,lutein, 3'-epilutein, zeaxanthin,lutein epoxide, antheraxanthin, canthaxanthin, otdoradoxanthin, astaxanthin, violaxanthin, neoxanthin, auroxanthin, mutatoxanthin, azafrin, and apo-12-violaxanthal. Azafrin is reported for the first time from lichens in Pseudocyphellaria coronata. The total content of carotenoids ranged from 15.16 IJ.g g--i dry wt in Pseudocyphellaria chloroleuca to 298.78 ~tg g-Z dry wt in Pseudocyphellaria coronata.

Column and thin‐layer chromatography revealed the presense of the following carotenoids in the thalli of 20 lichen species from Primorski Territory and North Korea: α‐carotene, β‐carotene, lycoxanthin, lycophyll, rubixanthin, β‐cryptoxanthin, zeaxanthin, lutein, 3′‐epilutein, lutein epoxide, antheraxanthin, adonixanthin, phoenicoxanthin, canthaxanthin, astaxanthin, neoxanthin, violaxanthin, mutatoxanthin, auroxanthin, luteoxanthin, rhodoxanthin, capsochrome, apo‐12′‐violaxanthal and β‐citraurin. The total content of carotenoids ranged from 16.6 (Parmelia caperata) to 82.4 μg g−1 dry weight (Alectoria lata).
