Fast atom bombardment mass spectrometry and linked scan analyses at constant B/E in the structural characterization of new polyisoprenepolyols isolated from an edible mushroom (Hypsizigus marmoreus)

Abstract

Fast atom bombardment (FAB) mass spectrometry is a powerful tool for analyzing the structure of polyisoprenepolyols. Analyses in the positive and negative ion mode are complementary in that the former provides data on the number of hydroxy groups present while the latter provides data on the isoprenoid sequence. Some of this information is already available from routine FAB mass spectra. More detailed information is contained in the linked scan spectra.
