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