✦ Synopsis
Five di!erent extraction methods, namely hydrodistillation, solvent extractions using hexane, diethyl ether and chloroform, and supercritical #uid extraction using supercritical carbon dioxide were used to extract lemon oil from an inclusion complex of -cyclodextrin and lemon oil. The extraction e$ciency and volatile pro"les of 10 major selected volatiles in extracted oil were compared using GC}MS.
Volatile #avour components of the complex were successfully extracted by hydrodistillation under carefully controlled conditions. All three solvents, hexane, diethyl ether and chloroform, can be used for extraction of volatiles from the complex, however, hexane was more e$cient and easier to handle, with the organic phase easy to separate. Chloroform was the most ine$cient in terms of phase separation. The supercritical #uid extraction (SFE) method was not successful and extracted only 33% of the total encapsulated oil after 7 h at 453C and 210 kg/cm. The volatile pro"les of the solvent extracted oil were similar, SFE was signi"cantly di!erent from the other four methods and hydrodistilled oil was also di!erent, but closer to the solvent extracted oil.
