Three lanostane triterpenoids, aeruginosols A, B and C, from the fruiting bodies of Stropharia aeruginosa

Phytochemical analysis of the MeOH extract of the fruiting bodies of Stropharia aeruginosa resulted in the isolation of three lanostane triterpenoids, aeruginosols A, B and C. The structures of the new compounds were determined by spectroscopic analysis. The biological activities of aeruginosols A, B and C were examined by bioassay with lettuce seedling.
