3β-Hydroxy-lanosta-8,24-dien-21-al, a New Triterpene fromInontus obliquus

A new triterpene, 3beta-hydroxy-lanosta-8,24-dien-21-al, was identified from INONOTUS OBLIQUUS. The structure was determined by IR, MS, (1)-NMR and (13)C-NMR spectroscopy and by comparing its (13)C-NMR spectra with the spectra obtained for lanosterol, inotodiol, trametenolic acid and methyl trametenolate.
