The coarsely powdered drug Quassia amara was digested 
three times v;ith 50-60 percent alcohol, the liquids mixed and 
treated with a little freshly burned magnesia, a little acetic 
acid added, if necessary, to produce a slight acid reaction, and 
the solution filtered, after which the alcohol was expelled at 
the lowest possible temperature. The aqueous solution thus 
obtained was warmed gently in an open dish, and the water was 
replenished from time to time, so as to get rid of all alcohol. 
On Cooling, the separated resin was removed and the liquid 
.repeatedly shaken up with chloroform. Erom the separated 
Chloroform solution the chloroform was distilled off and the 
residue treated with a mixture of absolute alcohol and ether;
