Apoatropine (atropatropine) is a member of class of tropane alkaloids. Chemically, it is an ester formed from tropine and atropic acid. Apoatropine can be found in plants of family Solanaceae. It is a bitter crystalline alkaloid. Examples of related tropane alkaloids include atropine, hyoscyamine, and hyoscine. Though apoatropine is found in various plants, it can also be prepared by the dehydration of atropine using nitric acid . Apoatropine is used as a pigment.^{[citation needed]}
