✦ Synopsis

The new triterpene trio1 3/3,15a,22-trihydroxyhopane, the triterpene diol dustanin (15n,22-dihydroxyhopane) and the sterol ergosterol were isolated from the entomogenous fungus Aschersonia aleyrodis. During our study on carotenoids of the entomogenous fungus Aschersonia aleyrodis' CBS 541.73 we isolated an amount of white crystalline material. Separation by column chromatography (sephadex LH 20) and preparative TLC yielded the well-known fungal sterol ergosterol and two other compounds with a mass spectrometric fragmentation characteristic for pentacyclic tri-terpenes2. The molecular formula C30H5202 of the major compound (mp. 261-264') was established
