Isolation of diterpenoid alkaloids from herb and flowers of aconitum napellus ssp. vulgare and electrospray ion trap multiple MS study of these alkaloids
Chemical investigation of herb and flowers of Aconitum napellus L. ssp. vulgare led to the isolation of 12 diterpenoid alkaloids. Their chemical structures were identified on the basis of NMR and MS and of their complete ion trap multiple fragmentation mass spectrometry study.
