| Abstract
| - Two new lanostane-type triterpenoids, 3α,16α-dihydroxylanosta-7,9(11),24-trien-21-oic acid (1) and 3α,16α,26-trihydroxylanosta-7,9(11),24-trien-21-oic acid (2), along with three known lanostanoids, 16α-hydroxy-3-oxolanosta-7,9(11),24-trien-21-oic acid (3), 3α-carboxyacetoxy-24-methylen-23-oxolanost-8-en-26-oic acid (4), and 3α-carboxyacetoxy-24-methyl-23-oxolanost-8-en-26-oic acid (5), have been isolated from the EtOAc extract of the fruiting body of Ganodermaapplanatum. The structures of 1, 2, and 3 were determined directly by the interpretation of spectroscopic data, while thestructures of 4 and 5 were assigned by comparison of spectroscopic data against literature values.
