Patent ID: 8722105

Claim:
An isolated fraction of mastic gum produced by a process consisting of the steps of: (a) treating mastic gum with a polar organic solvent; (b) isolating a fraction soluble in said polar organic solvent; (c) optionally removing said polar organic solvent; (d) treating the soluble fraction obtained in step (b) or (c) with a non-polar organic solvent; (e) isolating a fraction soluble in said non-polar organic solvent; and (f) removing said non-polar organic solvent, wherein the fraction is characterized in that it is soluble in at least one polar organic solvent and in at least one non-polar organic solvent, and wherein said fraction is substantially devoid of compounds which are soluble in said polar organic solvent but insoluble in said non-polar organic solvent and wherein extraction with the polar organic solvent precedes extraction with the at least one non-polar organic solvent.
