Beschreibung

A aconite alkaloid present in Aconitum fischeri Reich, A. sachalinense, Fr. Schmidt (Saghalien) and A. subcuneaturn, Nakai, this base is amorphous but yields crystalline salts, e.g. the perchlorate, m.p. 230-2°C (dec.); aurich10ride, m.p. 208-9°C (dec.) and a perbromide, m.p. 181-2°C (dec.). Boiling dilute H2S04 causes hydrolysis with the production of acetic acid and jesanisaconine (p-anisoylaconine) forming a crystalline hydrochloride, m.p. 209- 21 O°C (dec.).Alkaline hydrolysis gives acetic and p-anisic acids and aconine. Pyrolysis furnishes pyrojesaconitine, obtained as the crystalline perchlorate, m.p. 171-2°C; [α]13D - 27.4° (MeOH). Oxidation with KMn04 yields acetaldehyde, indicative of an ethylimino group. The structure of the alkaloid has been determined by con_x0002_tinuous monitoring of the pyrolysis and an examination of the products produced.
Jesaconitine is, like all of the aconitines, highly toxic producing raspiratory paralysis and a direct toxic action on the heart, the latter often terminating in ventricular fibrillation.

Occurrence

A complex aconitine alkaloid, yunaconitine has been isolated from Aconitum hemsJeyanum.
