Fernene triterpenoids from the lichen Pyxine berteriana

Two new fernene triterpenoids, fern-9(11)-en-3,19-dione (1) and 3β-acetoxyfern-9(11)-en-19-one (2), together with the known 3β-acetoxyfern-9(11)-en-19β-ol (3) and lichexanthone (4), have been isolated from the acetone extract of the lichen Pyxine berteriana. The structures of the new compounds were...
