1) Two kinds of aconite plants (Ochiai No.3 and No.4) were collected near Jofukuji, Kajigamori, Kochi Prefecture, and their alkaloidal components were examined. Specimen No.3 yielded hypognavine as the chief component and a new Kajigamori Base as prismatic crystals of m. p. 107-110°, [α]D28 0±0.5° (CHCl3), C21H21-23O4N-(OCH3)2 (no ester group according to the infrared spectrum). Specimen No.4 contained mesaconitine as the chief component and a small amount of hypaconitine. These results revealed that the Kajigamori plants reported earlier had been a mixture of the Specimens No.3 and No.4.
2) Plants collected in the mountains of Katsuyama, Fukui Prefecture, were examined.
a) The specimen (Ochiai No.2) collected around Wasadani yielded hypognavine, Kajigamori Base, and a new Katsuyama Base-I as prisms, m. p. 283-285°, [α]D24: +90.93° (MeOH), C22H27-29O3N (no ester group according to the infrared spectrum), indicating that the Wasadani and Kabeshita specimens reported earlier had been mixed with the Akakabe specimen (Ochiai No.1).
b) The specimen (Ochiai No.22) collected around Ipponmatsu area yielded a new Katsuyama Base-II as needles, m. p. 243-245° (decomp.), C29H35O6N (presence of benzoyloxy and acetyloxy groups indicated by the infrared and ultraviolet spectra).
3) The aconite plants collected in Hieizan, Kyoto Prefecture, and Bunagatake, Shiga Prefecture, were found to contain ignavine and mesaconitine as the chief components and to be identical in componental makeup as the specimen (Ochiai No.1) collected in Akakabe, Katsuyama, Fukui Prefecture.
