Abstract:
Introduction:Lichen is a stable symbiotic complex formed by fungi and symbiotic algae.
There are many kinds of lichens, which are cold and drought resistant, and have strong adaptability
to the environment. Lichens can grow and reproduce in places where other organisms are difficult
to survive. Apart from their ecological importance, they have become important natural medicinal
resources due to the production of a large number of unique secondary metabolites (depsides, depsidones, dibenzofurans, pulvinic acid derivatives) and pigments (anthraquinones, napthoquinones,
and xanthones) which can act as biomarkers as well as bioactive compounds. Usnea longissima
Ach. is a hanging hair lichen, that grows circumpolar in high humidity inland areas and coastal forests of Europe, Asia, and North America. This lichen has been used therapeutically for centuries
in Mongolian traditional systems of medicine for its analgesic, cardiotonic, stomachic, and wound
healing properties. Recently, many scholars have studied the chemical constituents and biological
activities of Usnea longissima Ach and its related varieties, and obtained gratifying results. Previous studies on its chemical constituents have resulted in isolation of several bioactive secondary
metabolites which include monosubstituted phenyls, depsides, anthraquinones, dibenzofuran derivatives, and terpenoids. In order to understand the clinical application and devote to the deeper
scientific research and development, the pharmacological literature of Usnea longissima Ach was
sorted out in this study.
Methods:Collect and sort out the modern periodical literature and the related pharmacological
studies of Usnea longissima Ach in academic websites.
Result and Conclusion:The pharmacological studies of Mongolian medicine Usnea longissima Ach were studied in this paper. Usnea longissima Ach has a long history of medicinal use, which is recorded in the traditional medical materials of Tibetan, Mongolian, Uygurs, Tai and other ethnic minorities, as well as traditional Chinese medicine. According to the records, different nationalities in different countries have their own traditional medical theories as the basis for the diagnosis and treatment of different diseases. Previous studies on its chemical constituents have resulted in isolation of several bioactive secondary metabolites which include monosubstituted phenyls, depsides, anthraquinones, dibenzofuran derivatives, and terpenoids. The Usnea longissima Ach tastes bitter and it has the function of anti-bacterial, antioxidant, anti-cancer and detoxification effects. But it requires further study such as extract, isolate, and analyze the more chemical ingredients and its pharmacological activity.
