Selective Removal of Monoterpenes from Bergamot Oil by Inclusion in Deoxycholic Acid

A new approach for removing monoterpenes (MTs) from bergamot oil by selective inclusion in deoxycholic acid (DCA) is proposed. The inclusion process is very efficient, the included fraction being composed mainly of limonene (71.7%) and g-terpinene (19.8%). On the other hand, the deterpenated bergamot oil fraction showed for the linalool and linalyl acetate derivs. significant increases from 16.6 and 21.4% to 18.3 and 42.2%, resp. The major advantages of this methodol. are its simplicity, the mild conditions employed, and the quant. recovery of both host (DCA) and guest monoterpenes) compds. Differential scanning calorimetry (DSC), thermal gravimetry (TG), powder X-ray diffractometry (XRPD), IR spectroscopy (IR), and proton magnetic resonance (1H NMR) anal. were used to investigate and characterize the inclusion compds.
