title: Oxygenated lanostane-type triterpenoids from the fungus ganodermalucidum.
abstract: Two new triterpenoids, 20(21)-dehydrolucidenic acid A (1) and methyl 20(21)-dehydrolucidenate A (2), and five new 20-hydroxylucidenic acids, 20-hydroxylucidenic acid D(2) (3), 20-hydroxylucidenic acid F (4), 20-hydroxylucidenic acid E(2) (5), 20-hydroxylucidenic acid N (6), and 20-hydroxylucidenic acid P (7), were isolated from the fruiting body of the fungus Ganoderma ludicum, and their structures were established on the basis of spectroscopic methods.
