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.

Three lanostane triterpenoids from the fruiting bodies of Stropharia aeruginosa.

Three new lanostane triterpenoids, aeruginosic acid derivatives, were isolated from the fruiting bodies of Stropharia aeruginosa and their structures were determined on the basis of spectral data.

N-Phenethylhexadecanamide from the edible mushroom Laetiporus sulphureus.

N-Phenethylhexadecanamide was isolated from the MeOH extract of the fruiting bodies of the mushroom Laetiporus sulphureus together with eburicoic acid. Their structures were elucidated by spectroscopic methods.

Three oxygenated cyclohexenone derivatives produced by an endophytic fungus.

Three cyclohexenone derivatives, (4S,5S,6S)-5,6-epoxy-4-hydroxy-3-methoxy-5-methyl-cyclohex-2-en-1-one (1), (4R,5R)-4,5-dihydroxy-3-methoxy-5-methyl-cyclohex-2-en-1-one (2), and (4R,5S,6R)-4,5,6-trihydroxy-3-methoxy-5-methyl-cyclohex-2-en-1-one (3), were isolated from unpolished rice fermented with an xylariaceous endophytic fungus (strain YUA-026). The structures of three compounds were established on the basis of spectroscopic analyses and chemical conversion. The minimum inhibitory concentrations of 1 and 3 were 100 microg/ml and 400 microg/ml against Staphylococcus aureus, 100 microg/ml and 200 microg/ml against Pseudomonas aeruginosa, and 200 microg/ml and >400 microg/ml against Candida albicans, respectively.

Fascicularones A and B from a mycelial culture of Naematoloma fasciculare.

Two sesquiterpenoids, fascicularones A and B, have been isolated from the culture broth of a poisonous mushroom, Naematoloma fasciculare. Their structures were determined using spectroscopic methods.
