[Abstract]
Object A systematic study on the chemical constituents of Fuscoporia oblique Fr. Te. LáT was carried out.Methods The constituents were isolated on silica gel column chromatography, identified by physico-chemical properties and structurally elucidated by spectral analysis (MS,?1H,13CNMR and IR).Results 9 compounds were identified, namely fuscoporine (Ⅰ), lanosterol (Ⅱ), 3β-hydroxy-lanosta-8, 24-diene-21-al (Ⅲ), 3β, 21-dihydroxy-lanosta-8, 24-diene (Ⅳ), 3β-hydroxy-lanosta-8, 24-diene-21-acid (Ⅴ), 3β, 22R-dihydroxy-lanosta-8, 24-diene (Ⅵ), ergosterol peroxide (Ⅶ), analog of sphingin (Ⅷ) and mannitol(Ⅸ).Conclusion Compound I is a new pigment and named as fuscoporine.
