Methylecgonine, also known as ecgonine methyl ester is a prominent tropane alkaloid found in coca leaves. It is metabolite of cocaine, and may be used as a precursor for it. It also occurs as minor alkaloid in roots of many Datura species such as Datura stramonium and Datura innoxia. ==Alkaloids== Cocamine (a-Truxilline) aka isatropylcocaine [490-17-5] and isococamine (beta-Truxilline) [490-15-3] are alkaloids present in Erythroxylun truxillense Rusby.

Methylecgonine, also known as ecgonine methyl ester is a prominent tropane alkaloid found in coca leaves. It is metabolite of cocaine, and may be used as a precursor for it. It also occurs as minor alkaloid in roots of many Datura species such as Datura stramonium and Datura innoxia. ==Alkaloids== Cocamine (a-Truxilline) aka isatropylcocaine [490-17-5] and isococamine (beta-Truxilline) [490-15-3] are alkaloids present in Erythroxylun truxillense Rusby. The Victorian era references disclosed in John Glasby's dictionary of alkaloids indicate the longevity of these compounds. Although these citations are outdated, a newer citation proposes different structures. These compounds are understood to be esters of truxillic acid and/or truxinic acid that are formed as a consequence of methylecgonine cinnamate photodimerizing. Cocamine was reported to be a heart poison in later work.
== Biosynthesis == It is the last step before cocaine is biosynthesized in coca plants with the help of BAHD acyltransferase.
