Received Date: 7 July 2008

Fund Project: The work was supported by the National 863 Program of China (No. 2007AA09Z403), and National Key Technology Research and Development Program of China (No. 2007BAI37B05), and Natural Science Foundation of Gansu Province (No. 0710RJZA120).

A new depsidone, diffractione A (1), as well as six known phenolic compounds (2-7) were isolated from Usnea diffracta. Their structures were elucidated by 1D and 2D NMR spectroscopy together with HRESIMS analysis. All components were obtained for the first time from U. diffracta.
