ABSTRACT
Considerando que a Aromaterapia vem ao longo do tempo se consolidando como prática de grande relevância no tratamento de infecções e outras doenças do homem, decidiu-se produzir um levantamento exploratório bibliográfico desde sua origem até os dias atuais, com o intuito de acentuar cada vez mais a curiosidade e o conhecimento sobre essa arte e ciência milenar, que se apoia no uso racional dos óleos essenciais.
Over time, Aromatherapy has consolidated itself as a traditional and important practice for the treatment of infections and diseases of men. The purpose of the study is to conduct an exploratory literature review that encompasses its origin and its present-day scenario. Our intention is to call attention to the curiosity and knowledge that exists about this ancient art and science, which is based on the rational use of essential oils.

Bioskin is a natural product produced by a mixed culture of Acetobacter xylinum, Saccharomyces cerevisiae and S. pombe cultured on media containing sucrose. It is of fibrillar nature able to retain some proteins, such as cytochrome c, by adsorption, and mainly composed of glucosamine and N-acetyl-D-glucosamine. This makes it possible that, at an adequate pH value, proteins charged as polyanionic molecules, such as catalase, can be retained by ionic adsorption using the positively charged amino groups of the matrix. In addition, bioskin can also be used as an affinity matrix to retain glycoproteins able to perform specific affinity reactions with the amino sugars of the matrix, such as invertase, fetuin or ovalbumin. Its possible use as a chromatographic support is discussed.

The production of both ribitol (which is the translocatable form of reduced carbon) and mannitol (which is the main accumulation form of carbon) by thallus samples of Cladonia sandstedei increases when exogenous urea is supplied to the lichen. In addition, the synthesis of atranorin and its precursor, methyl ß-orcinol carboxylate, is also enhanced by urea. A hypothetical action of ammonia released from this nitrogen source on these metabolic processes is suggested.
ABSTRACT
Duas substancias, extraidas de Cladonia sandstedei Abb., podem ser comparaveis a atranorina e ao beta-metilorcinol carboxilato, com base em estudos de espectroscopia de massa, ressonancia magnetica nuclear a infravermelho. Somente atranorina foi testada "in vitro", pois apresentou melhor rendimento. Foi testado a atividade microbiologica da atranorina, mostrando-se esta, efetiva para Staphylococcus aureus, Escherichia coli e Bacillus cereus e para os leveduriformes Candida albicans, Candida stellatoidea, em algumas doses nos meios liquidos e solido
