“…As reported previously, m ‐cresol and p ‐cresol have different contributions to the overall aroma of the matrix, due to their different flavour character and odour threshold . In contrast, a modification of the method from Mauri‐Aucejo and co‐workers, as well as our research team, using β ‐CD as a mobile phase component, offered good separation for the volatile phenols tested, especially for m ‐cresol and p ‐cresol, both in standard mixtures and real samples. Therefore, to obtain good chromatographic separation of 10 target volatile phenols, β ‐CD was utilized as a resolving agent in the mobile phase, and gradient elution with mobile phase A and mobile phase B was also performed.…”

Volatile phenols have been considered as a class of highly flavour‐active compounds in non‐alcoholic and alcoholic beverages. However, the information on volatile phenols in Chinese liquors remains limited. This article presents a high‐performance liquid chromatography with a fluorescence detector (HPLC‐FLD) method for the determination of 10 volatile phenols in Chinese liquors. The method was based on the fluorescent nature of volatile phenols, the separation of the isomers p‐cresol and m‐cresol with β‐cyclodextrin as the resolving agent, and the use of a protective barrier layer for the capture of volatile phenols during the concentration process of the extract solution. The effects of several experimental parameters on recoveries of target volatile phenols were investigated. The correlation coefficients (R2) for calibration curves of the 10 phenols studies were in the range 0.9991–0.9998 when the linearity range was from 0.05 to 4 µg/ml. The proposed RP‐HPLC method was successfully applied to the analysis of Chinese liquors and the recoveries of the phenols were in the range 91.5–100.4% with RSD 0.9–2.2%, and the limits of detection were 0.0072–0.0234 µg/ml. Volatile phenols of different types and in differing amounts were found in several Chinese liquors. The method could be of use for routine evaluation of the quantity of volatile phenols during the production and ageing process of Chinese liquors. Copyright © 2013 John Wiley & Sons, Ltd.

“…Also, note that the presence of multiple peaks with the use of chiral separation media does not guarantee that the separations obtained are chiral. For instance, cyclodextrin-based selectors have also been used to separate ortho-, meta-, and para-isomers (152,153). To circumvent these issues, numerous strategies have developed.…”

The main goal of this review is to provide a brief overview of chiral separations to researchers who are versed in the area of analytical separations but unfamiliar with chiral separations. To researchers who are not familiar with this area, there is currently a bewildering array of commercially available chiral columns, chiral derivatizing reagents, and chiral selectors for approaches that span the range of analytical separation platforms (e.g., high-performance liquid chromatography, gas chromatography, supercritical-fluid chromatography, and capillary electrophoresis). This review begins with a brief discussion of chirality before examining the general strategies and commonalities among all of the chiral separation techniques. Rather than exhaustively listing all the chiral selectors and applications, this review highlights significant issues and differences between chiral and achiral separations, providing salient examples from specific classes of chiral selectors where appropriate.
