“…One year later, the same research group developed a fully automatic on-line LC-GC-MS system for the analysis of bergamot oil; in that case, 67 components were identifi ed among the volatiles, which were subjected to separation into chemical classes by means of LC. [9] The same system was used in 1995 for elucidating the sesquiterpene fraction of bergamot oil. [10] A series of studies on genuine bergamot oils produced in Calabria enlarged knowledge on the chemical composition of this valuable oil.…”

Bergamot oil (Citrus bergamia) is mainly employed in the perfumery and cosmetic industries and also, in a smaller amount, in the pharmaceutical and food industries, for its fragrant notes, fi xative and antimicrobial properties. Due to the presence of some phototoxic compounds in its composition, it has become a common practice to reduce or sometimes completely eliminate these substances before using the oil. Samples of treated bergamot oils have been investigated in this study (terpeneless, furocoumarin-and bergapten-free) by means of GC-FID, GC-MS, enantio-GC-FID and HPLC. The results are reported in terms of either peak areas or g/100 g. Some considerations are made in order to discuss the technologies used for treating bergamot oil.

“…The analysis of food products may be directed to the assessment of food quality and authenticity, the control of technological processes, the determination of nutritional value and the detection of molecules with a possible beneficial or toxic effect [1]. The determination of triacylglycerols (TAGs) in lipids is highly important due to their fundamental role in the maintenance of good health [2].…”

The presence of tallow in lard is not easy to determine, due to the similarity of the composition of these two animal fats, which differ mainly in the distribution of fatty acids (FA) in the three positions of the glycerol molecule. The determination of the composition of the triacylglycerol (TAG) fraction of lard, tallow, and their mixtures was investigated by HPLC in combination with atmospheric pressure chemical ionization mass spectrometry (APCI-MS). The presence of tallow in lard was determined through the study of the sn-POP/sn-PPO ratio by multidimensional HPLC. The off-line bidimensional system was attained through the coupling of non-aqueous reversed phase (NARP)-HPLC and silver ion (Ag)-HPLC. The primary column eluate was fractionated and the fraction containing POP/PPO isomers was injected onto the secondary column, allowing the separation of positional isomers, unresolved in the first dimension. Peak assignment was carried out by combining retention data with APCI-MS spectral information. The fatty acid distribution along the glycerol backbone, determined by Ag-HPLC, was confirmed through diglyceride ion ratios derived from APCI-MS analysis. Method validation was carried out in preliminary applications on standard TAGs. The analytical results obtained show that even a 5% addition of tallow to lard modifies the distribution of positional isomers.

“…[3][4][5][6][7][8][9][10] Some relatively recent papers have reported the on-line HPLC preseparation/concentration and HRGC analysis of various volatile fractions in a fully automated mode. [3][4][5][6] These effective separations have concerned monoterpene and sesquiterpene hydrocarbons and their oxygenated derivatives, as well as aliphatic compounds. LC-GC has also been employed for the determination of enantiomeric ratios.…”

Comprehensive two-dimensional GC for the analysis of citrus essential oils

et al. 2005

The lemon essential oil volatile fraction is considered one of the most complex amongst all citrus oils being traditionally determined by monodimensional GC. This conventional method, although providing important qualitative/ quantitative information, lacks the necessary resolving power for the separation of several critical compounds. In the past, this has been often accomplished through the employment of conventional multidimensional chromatographic methods, which can only achieve the characterization of single parts of a sample and whose analysis times are generally high. Comprehensive bidimensional gas chromatography (GC × × × × × GC) is gaining an excellent reputation for the separation of complex samples. This powerful analytical technique is characterized by both an enhanced resolving power and a great potential for the classification of unknowns through chromatographic retention patterns. In this research, these features are exploited in the analysis of a lemon essential oil.
