[Abstract] Objective： To study the chemical constituents of the whole lichen of Usnea longissima. Method： The compounds were separated by silica gel， Sephadex LH-20 chromatography and high performance liquid chromatography(HPLC). The structures of the compounds isolated were identified by physico-chemical properties and spectral analysis. Result： Ten compounds were isolated and their structures were identified as (4aR，9bS)-2，6-diactyl-3，4a，7，9-tetrahydroxy-8，9b-dimethyl-1-oxo-1，4，4a，9b-tetrahydrodibenzo[b，d]furan (1)， (+)-usnic acid (2)， orcinol (3)， 18R-hydroxydihydroalloprotolichensterinic acid (4)， 5， 8-epidioxy- 5α， 8α-ergosta-6， 22E-dien-3β-ol (5)， ethyl everninate(6)， arabitol(7)， apigenin 7-O-β-D-glucuronide(8)， 3-hydroxy-5-methoxy-2-methylbenzoic acid(9)， friedelin(10). Conclusion： Compound 1was a new compound. Compound 8 was isolated from genu Usnea for the first time and compounds 3， 4 and 7 were isolated from U. longissima for the first time.
