The Aconitum spicatum, as tranditional herb, extracts have been employed in analgesic balms for migraine in Chinese Tibet area. Investigation of Aconitum spicatum stapf in ann. resulted in the isolation of two new nor-diterpenoid alkaloids,i.e.,spicatineA, spicatineB, along with nine known compounds. The structures of these new compounds were deduced on the basis of their spectral date(1D,2D-NMR,MS,IR)
