Three known alkaloids, isodelphinine, sachaconitine and miyaconitine except miyaconitinone were isolated from Aconitum neosachalinense Lev. [Hiroha Karafutobushi] which is distributed over the suburbs of Yuzhino-sakhalinsk in Sakhalin island. The identification of these alkaloids was shown very effectively in the both of Ms・1 and Ms・2 spectra on the use of V. G. Quattro Instrument by the method of Electrospray Ionization (ESI). By this method, it is confirmed that there are jesaconitine as the characteristic component in all of the distribution region on A. japonicum Thunb. ex Murray subsp. subcuneatum (Nakai) Kadota [Okutorikabuto]. Several alkaloids were identified in A. iidemontanum Kadota [Iide-torikabuto] having chromosome number 2n=2x=16. Moreover, a new major alkaloid, nippocunamine, was isolated from A. nipponicum Nakai (Miyama-torikabuto) which is an alpinetype species and chromosome number 2n=4x=32.
