Cathinone (also known as benzoylethanamine, or β-keto-amphetamine) is a monoamine alkaloid found in the shrub Catha edulis ( khat) and is chemically similar to ephedrine, cathine, methcathinone and other amphetamines. It is probably the main contributor to the stimulant effect of Catha edulis. Cathinone differs from many other amphetamines in that it has a ketone functional group. Other phenethylamines that share this structure include the stimulants methcathinone, MDPV, mephedrone and the antidepressant bupropion among others.
