Patent ID: 8445037

Claim:
A process for preparing an adjuvant composition capable of increasing the bioavailability of a bioactive composition, comprising: a. subjecting dried mint leaves to direct steam heat to obtain a crude mint oil; b. heating said crude mint oil while applying and increasing a vacuum to volatilize and condense discreet fractions of said crude mint oil; c. collecting said discreet fractions of said crude mint oil and separating low-boiling fractions as byproduct fractions from higher boiling flavor fractions; d. analyzing the discreet byproduct fractions obtained in step c; and e. selecting and combining suitable byproduct fractions so as to obtain an adjuvant composition comprising less than 10% limonene and less than 5% of any of menthol, menthone, menthofuran, menthyl acetate and germacrene D.
