Methylecgonidine Names Ecgonine (tropane derivative) is a tropane alkaloid found naturally in coca leaves. It has a close structural relation to cocaine : it is both a metabolite and a precursor , and as such, it is a controlled substance in many jurisdictions, as are some substances which can be used as precursors to ecgonine itself.
