INTRODUCTION
Coca leaves contain alkaloids derived from ecgonine, including cocaine, cinnamylcocaine (cinnamoylcocaine), a-truxilline and β-truxilline. Alkaloids such as hygrine, hygroline and cuscohygrine, which are based on the structure of hygrine, are also constituents of coca leaves. Tropacocaine and other alkaloids based on the structure of φ-tropine are also present.4
