Aconitine, also known as acetylbenzoylaconitane, is a C19 norditerpenoid alkaloid. Its molecular formula is C34H47NO112. It has 3 hydrogen bond donors, 12 hydrogen bond acceptors, 7.7 flexible bonds. Aconitine belongs to the family of aconitum alkaloids and is barely soluble in water, but very soluble in organic solvents such as chloroform or diethyl ether. Aconitine is also soluble in mixtures of alcohol and water if the concentration of alcohol is high enough. Aconitine is synthesized by the aconitum plant via terpenoid biosynthesis from methylerythritol phosphate pathway that polymerizes subsequent to phosphorylation.
