| trehalose esters from the aspen fungus hyphozyma lignicola. | chemical investigation of the metabolites produced when a new fungus, hyphozyma lignicola, isolated from blackgalls on aspen, was grown in malt extract liquid medium resulted in the isolation and identification of five trehalose esters 1-5, which are unusual fungal metabolites. the major compound is 3,6-di-o-acetyl-2-o-octadecanoyl-alpha,alpha-d-trehalose [2]. the structures were established by the analysis of nmr and fabms data in combination with chemical degradation. | 1993 | 8133295 |
