“…Flavanones and catechin were also enantioseparated with highly succinylated cyclic b-(1,2)-a-(1,6) glucans (family III) on CE [28,115]. Using highly sulfated cyclic b-(1,2) glucans, basic chiral drugs were separated via strong ionic interactions on the CE system, and some chiral flavonoids were successfully visualized in micellar electrokinetic chromatography [98,116].…”

Cyclic b-glucans are unique constituents that are found in the periplasmic space and extracellular media of Agrobacterium, Rhizobium, Bradyrhizobium, Rhodobacter, Xanthomonas, and Ralstonia species. Based on their glycosidic linkages, they are classified into three groups composed of cyclic b-(1,2), b-(1,3)-b-(1,6), and b-(1,2)-a-(1,6) linked glucans. Their degrees of polymerization vary ranging from 10 to 40 glucose residues, and the backbone structure can be modified with non-sugar moieties. Since the macrocyclic oligosaccharides possess their own characteristics such as inherent three-dimensional structures, hydrogen bonding, and complex-forming abilities, various possible applications would be of interest in the field of green chemistry, separation science, pharmaceutical, and food industries. In this review, we have addressed the properties and current applications of bio-sourced cyclic bglucans and their derivatives.

“…A glucose‐derived cyclic oligosaccharide different from CDs, which has been studied as chiral selector is α‐cyclosophorooctadecaose (α‐C18), a macrocycle produced by Rhodobacter sphaeroides . α‐C18 is composed of 18 glucose units linked by β‐(1→2) linkages and one α‐(1→6) linkage and highly substituted by acetyl and succinyl groups.…”

“…α‐C18 is composed of 18 glucose units linked by β‐(1→2) linkages and one α‐(1→6) linkage and highly substituted by acetyl and succinyl groups. The selector was applied for the CE enantioseparation of catechin and flavanones and flavanone‐7‐ O ‐glycosides . The succinyl residues proved to be essential for the recognition of the analytes because unsubstituted α‐C18 prepared by alkaline hydrolysis showed no enantioresolution.…”

Capillary electromigration techniques have developed into significant analytical separation tools especially for enantioseparations. While CE can be considered a mature technique as documented by its wide applications, CEC is still in a developmental state despite many research efforts. The success of stereospecific CE separation methods is due to the high specificity and flexibility of the technique as well as the availability of many types of chiral selectors. Thus, numerous methods have been developed for the analysis of chiral compounds in chemical, biochemical, pharmaceutical, environmental, and forensic sciences. However, most reported applications deal with pharmaceuticals. The search for new chiral selectors also continued despite the fact that most applications were performed using cyclodextrins. Furthermore, CE has been combined with spectroscopic and molecular modeling studies in attempts to understand the interactions between chiral selectors and analytes. The present review focuses on recent examples of mechanistic aspects of capillary enantioseparations with regard to mathematical modeling of enantioseparations, investigations of the analyte-complex structures as well as new chiral selectors and applications of chiral analyses by CE and CEC. It covers the literature published between January 2011 and August 2012.

This review is the seventh update of the original article published in 1999 on the application of MALDI mass spectrometry to the analysis of carbohydrates and glycoconjugates and brings coverage of the literature to the end of 2012. General aspects such as theory of the MALDI process, matrices, derivatization, MALDI imaging, and fragmentation are covered in the first part of the review and applications to various structural types constitute the remainder. The main groups of compound are oligo- and poly-saccharides, glycoproteins, glycolipids, glycosides, and biopharmaceuticals. Much of this material is presented in tabular form. Also discussed are medical and industrial applications of the technique, studies of enzyme reactions, and applications to chemical synthesis. © 2015 Wiley Periodicals, Inc.
