“…In addition to well-established buffer systems novel additives have been reported for flavonoid analysis. Kwon et al [68] added microbial cyclic X-(1-3),(1-6)-glucans as chiral selectors to a borax buffer. This resulted in an excellent separation of several isomeric flavonoids such as R/S hesperitin, R/S naringenin or R/S isosakuranetin.…”

Herbal preparations, particularly those from traditional Chinese or Indian medicine, are becoming increasingly popular in Europe and the USA. Their application is often based on long-term historic use rather than on scientific evidences; thus, analytical tools to assure their efficacy, safety and consistency are in great demand. This review evaluates the importance of CE for quality control of herbal medicinal products during the last five years. After briefly describing the general characteristics of natural products analysis by CE, numerous applications on medicinal plants or herbal products are summarized. These examples not only reflect the enormous variability of CE with respect to buffer systems and detection modes employed, but also indicate an increasing importance of this separation technique for quality control purposes compared with more established ones such as HPLC.

This review is the fifth update of the original review, 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 2008. The first section of the review covers fundamental studies, fragmentation of carbohydrate ions, use of derivatives and new software developments for analysis of carbohydrate spectra. Among newer areas of method development are glycan arrays, MALDI imaging and the use of ion mobility spectrometry. The second section of the review discusses applications of MALDI MS to the analysis of different types of carbohydrate. Specific compound classes that are covered include carbohydrate polymers from plants, N- and O-linked glycans from glycoproteins, biopharmaceuticals, glycated proteins, glycolipids, glycosides and various other natural products. There is a short section on the use of MALDI mass spectrometry for the study of enzymes involved in glycan processing and a section on the use of MALDI MS to monitor products of the chemical synthesis of carbohydrates with emphasis on carbohydrate-protein complexes and glycodendrimers. Corresponding analyses by electrospray ionization now appear to outnumber those performed by MALDI and the amount of literature makes a comprehensive review on this technique impractical. However, most of the work relating to sample preparation and glycan synthesis is equally relevant to electrospray and, consequently, those proposing analyses by electrospray should also find material in this review of interest.

“…In fact, various bulky compounds such as amphotericin B, paclitaxel, indomethacin, reserpine, steroids, and vitamins have formed inclusion complexes with cyclic b-(1,2) glucans [22][23][24][25][26]. Recent study has also shown some results induced by the complexing ability of cyclic b-(1,3)-b-(1,6) and cyclic b-(1,2)-a-(1,6) glucans as well as the chemically derivatized cyclic b-(1,2) glucans [27][28][29][30][31].…”

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.
