Detection and distribution of nodulisporic acid analogs by liquid chromatography high-resolution mass spectrometry among fermentation extracts of selected endophytic and teleomorph-derived strains of Hypoxylon pulicicidum.

*

SeeTable 1 for strain details and Methods and Material for description of fermentation media and protocols.

Calculated (Calc.) m/z for the known nodulisporic acids and their dehydrated and Na+ adducts are given above. For each strain, the retention times (RT), measured (Meas.) m/z and error in ppm are given for each detected nodulisporic acid ion and its dehydrated and Na+ adducts, respectively.
