ISOLATION

 

 

The process of the isolation of resin from crude drug can be a difficult task due to the presence of various combinations. However the most generalized technique can be the extraction of the drug with alcoholic solvents and then subsequent precipitation of resin by adding concentrated alcoholic extract to a large proportion of water. The method of distillation or hydrodistillation can be used for the separation of volatile oils from resin. This process is used largely for the separation of resin from turpentine.
