Mass Spectra of Pentacyclic Triterpenoids

Mass spectra of more than one hundled saturated and unsaturated pentacyclic triterpenoids were examined. In general, the presence of nuclear double bond(s), vicinal methyl groups and functional group(s) controls the fragmentation behavior, and therefore the basic carbon skeleton with double bond(s)...

Summary:Mass spectra of more than one hundled saturated and unsaturated pentacyclic triterpenoids were examined. In general, the presence of nuclear double bond(s), vicinal methyl groups and functional group(s) controls the fragmentation behavior, and therefore the basic carbon skeleton with double bond(s) and functional group(s) of unknown compounds can be identified by consideration of the fragmentation pattern.
