چکیده
Coca-Erythroxylum coca Lamarck var. coca-remains one of the most common plants of the folk medicine of Bolivia used as a general stimulant. Aymara and Quechua natives prefer to chew the sweeter coca leaves from the Yungas (tropical mountain forests of the eastern slopes of the Andes) rather than those from the Chapare lowlands. The contents in cocaine and minor constituents of leaf samples cultivated in these regions does not rationalize this choice.

Inter- and intra-specific variation among five Erythroxylum taxa assessed by AFLP.
BACKGROUND and Aims The four cultivated Erythroxylum taxa (E. coca var. coca, E. novogranatense var. novogranatense, E. coca var. ipadu and E. novogranatense var. truxillense) are indigenous to the Andean region of South America and have been cultivated for folk-medicine and, within the last century, for illicit cocaine production. The objective of this research was to assess the structure of g...
متن کاملIdentification of Erythroxylum taxa by AFLP DNA analysis.
Erythroxylum coca, indigenous to the Andean region of South America, is grown historically as a source of homeopathic medicine. However, in the last century, cultivation of E. coca and several closely-related species for the production of illicit cocaine has become a major global problem. Two subspecies, E. coca var. coca and E. coca var. ipadu, are almost indistinguishable phenotypically; a re...
متن کاملDiurnal fluctuations of cocaine and potential precursors in leaves of Erythroxylum coca.
Cocaine is abundant in leaves of Erythroxylum coca var. coca Lam. Consequently, cocaine and two of its early biosynthetic precursors were monitored for 24 h to determine whether they fluctuated diurnally. E. coca was grown under controlled environmental conditions in a growth chamber in soil at pH 3.5. After 17.5 months of growth, leaves not less than 35 days old were harvested every 2 and 4 h ...
متن کاملGenetic Characterization by RAPD Analysis of Isolates of Fusarium oxysporum f. sp. erythroxyli Associated with an Emerging Epidemic in Peru.
ABSTRACT An epidemic of vascular wilt caused by Fusarium oxysporum f. sp. erythroxyli is currently occurring on Erythroxylum coca var. coca in the coca-growing regions of the Huallaga Valley in Peru. Random amplified polymorphic DNA (RAPD) analysis of isolates of the pathogen was undertaken to elucidate its genetic complexity, as well as to identify a specific DNA fingerprint for the pathogen. ...
متن کاملCan coca leaves contribute to improving the nutritional status of the Andean population?
BACKGROUND Coca leaves (Erythroxylum coca) have been promoted as a food that could address the dietary deficiencies of the Andean population, but this is based on nutrient analyses of a small sample of leaves. OBJECTIVE We assessed the nutritional potential of eight samples of coca leaves grown in different regions of Peru. METHODS We used AOAC techniques to measure nutrients, nutrient inhi...
