use | it is known that Usnea lichens contain difon and usnic acid. the extraction conditions of Usnea lichens, which can be applied to skin topical agents such as whitening agents and reduce the content of usnic acid, were studied. |
biological activity | Diffractaic acid is the main component of U. longissimi and can be used as an effective proapoptotic agent in various disease studies. Diffractaic acid also has analgesic and antipyretics effects. |
in vivo study | Diffractaic acid show an analgesic effect by Acetic acid-induced writhing and tail-pressure methods in mice. |
chemical properties | powder, soluble in methanol, ethanol, DMSO and other organic solvents, derived from Usnea Usnea diffracta Vain, Dihuang belongs to Dihuang Rehmannia glutinosa (Gaetn.) Libosch. ex Fisch. et Mey.. |
