An alkaloid is a naturally occurring nitrogenous organic molecule that has a pharmacological effect on humans and other animals. The name derives from the word alkaline ; originally, the term was used to describe any nitrogen-containing base (an amine in modern terms).
The first individual alkaloid, morphine, was isolated in 1804 from the opium poppy (Papaver somniferum). [1] Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral [2] and even weakly acidic properties. [3]

This article is a list of Acacia species (sensu lato) that are known to contain psychoactive alkaloids, or are suspected of containing such alkaloids due to being psychoactive. The presence and constitution of alkaloids in nature can be highly variable, due to environmental and genetic factors.
Some indole alkaloids interact with other types of receptors. Mitragynine is an agonist of the μ-opioid receptor. [30] Harmal alkaloids are antagonists to the GABA A-receptor, [59] and ibogaine – to NMDA-receptors. [60] Physostigmine is a reversible acetylcholinesterase inhibitor.
