A new 23,24,25,26,27-five-nortriterpenoid (1), named resinacein T, was isolated from an ethanol extract of the fruiting bodies in Ganoderma resinaceum of family Ganodermataceae, together with two known lanostane triterpenoids, 3β,7β,15α,24-tetrahydroxy-11,23-dioxo-lanost-8-en-26-oic acid (2), and resinacein O (3). The structures of compounds (1-3) were elucidated using NMR and MS methods.
Keywords: Ganoderma resinaceum; Ganodermataceae; Lanostane triterpenoids.
