TEK - Making a crude coca leaf extract ?

[Benga]

SWIM was wondering if any of you great minds would have an idea for performing a VERY CRUDE coca extraction, something which could be performed on the quantities used in coca chewing ( say 10g), the idea being to isolate the alkaloids from the plants, not seperating out cocaine only, but obtaining some form of paste which could used orally, as in coca chewing but bypassing the traditional 45 minutes of having leaves and base in your mouth for absorption through the mouth's mucous membranes.
with such small quantities, the extraction procedure shouldn't take long, say 45 minutes to one hour and should require all the labour and chemicals of an acid/base extraction.
Reconsidering the process of coca chewing, leaves are placed in mouth for 45 minutes, swimming in saliva ( slightly acidic) with an added base ( limestone paste, sodium bicarbonate, or traditional quinoa ashes).
this effectively extracts alkaloids ( including cocaine) which are then absorbed through the mouth mucosa. Would there be a way to work on this procedure and obtain some kind of extract ( maybe extracting in liquid, water and alcohol, using sodium bicarbonate and say citric acid, then filtering, evaporating, rinsing? ) in which the alkaloid mass would be seperated from the plant material and concentrated, thus allowing a more convinient use without going for actual cocaine isolation ? reading of other plant extractions, this has been on swim's mind for some time...
Any ideas or comments ?
