Abstract

The electron-impact fragmentation of six polyhydroxysteroids from the starfishPatiria pectinifera, including three glycosides, has been studied. In addition to the directions of fragmentation that are characteristic for sterols from other sources and for steroid compounds of other classes, fragments have been found that result from the unusual arrangement of hydroxy groups in the molecules of the samples investigated. Two breakdown pathways of the furanose ring have been found in the spectra of the glycosides.
