Extracts of six lichen species collected from Brazil and Antarctica were investigated for their potential toxicity radical-scavenging properties.The composition the extracts was using TLC NMR, leading to identification atranorin (1), along with salazinic (2), barbatic (3), a-alectoronic (4), a-collatolic (5), cryptochlorophaeic (6), caperatic (7), lobaric (8), protolichesterinic (9) acids.All acetone evaluated 2,2′-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging ability subjected Artemia...
Nine lichen extracts were evaluated for tyrosinase inhibition and toxicity against Artemia salina larvae. Extract compositions investigated by TLC NMR analysis. The activity of constituents was bioautography, the percent calculated based on dopachrome produced during a set time interval. Cladia aggregata , Cladonia dimorphoclada Stereocaulon ramulosum microcarpum active inhibition. Barbatic, usnic, anziaic acids an unidentified compound present in extracts, are possibly responsible...
Plant-derived products can assist in the healing process of dermal wounds. It has been demonstrated that Hancornia speciosa latex present angiogenic, osteogenic, anti-inflammatory, and antioxidant activities. Then, it could contribute to wound process. However, natural contact with skin may cause dermatitis. The objective this work was evaluate allergic irritant potential H. serum fraction using vitro assays. obtained results showed a slightly is not cytotoxic neither allergenic for human...
ABSTRACT Previously known only from the North and Central America, lichenized fungi Cladonia dimorphoclada Robbins is recorded for first time in South America. The specimens were found growing on soil, an open area at 1695 m alt., Southern Brazil. We present a distribution map, figures, comments.
