Various alkaloids obtained from the methanol extracts of the roots of
Securidaca Longipedunculata Fres. were studied using supercritical flu
id chromatography/mass spectrometry. This hyphenated method and parall
el unimolecular and collisionally activated decomposition experiments
on electron impact-generated molecular ions gave information on the st
ructure of compounds. The presence of the ergoline skeleton in some of
them was assigned.
