SWIM has a KG or so of Coca leaves SWIM's friend brought back from a trip to Peru that SWIM would like to use. SWIM is not interested in extracting and purifying cocaine from these leaves or trying to get high from them. SWIM is instead interested in methods which could easily and (somewhat) efficiently extract all of the various alkaloids from some of these leaves, perhaps into a tincture or powder which SWIM would add to food or beverages for use as a general purpose health tonic, appetite reducer, mood elevator, etc.
SWIM was thinking of drying the leaves, pulverizing and then triple extracting into a solution containing citric acid (pH <> 3) and hot 95% EtOH, then filtering off the plant material, followed by evaporation of the EtOH to yield the citrate salts of coca alkaloids.
Would this extract most of the good stuff from the leaves or would a more complex extraction bee required?
Thanks.
