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.
