This review describes the mass spectral fragmentation of trimethylsilyl (TMS) and related alkylsilyl derivatives used for preparing samples for analysis, mainly by combined gas chromatography and mass spectrometry (GC/MS). The review is divided into three sections. The first section is concerned with the TMS derivatives themselves and describes fragmentation of derivatized alcohols, thiols, amines, ketones, carboxylic acids and bifunctional compounds such as hydroxy‐ and amino‐acids, halo acids and hydroxy ethers. More complex compounds such as glycerides, sphingolipids, carbohydrates, organic phosphates, phosphonates, steroids, vitamin D, cannabinoids, and prostaglandins are discussed next. The second section describes intermolecular reactions of siliconium ions such as the TMS cation and the third section discusses other alkylsilyl derivatives. Among these latter compounds are di‐ and trialkyl‐silyl derivatives, various substituted‐alkyldimethylsilyl derivatives such as the tert‐butyldimethylsilyl ethers, cyclic silyl derivatives, alkoxysilyl derivatives, and 3‐pyridylmethyldimethylsilyl esters used for double bond location in fatty acid spectra. © 2019 Wiley Periodicals, Inc.

Simultaneous determination of flavonoids in different citrus fruit juices and beverages by high-performance liquid chromatography and analysis of their chromatographic profiles by chemometrics

et al. 2012

Citrus fruits are of great interest because they contain flavonoids which are health promoting substances. Hesperidin, nobiletin and tangeretin are flavonoid glycosides that occur naturally in citrus. In the present study, a reversed-phase high-performance liquid chromatographic method has been developed for the rapid separation and determination of hesperidin, nobiletin and tangeretin in different fresh citrus fruit juices and commercial citrus beverages. Furthermore, principal component analysis was applied to their chromatographic profiles. Classification of orange, mandarin and hybrid was achieved. The possibility of estimating the approximate juice content of commercial beverages based on their PC1 values was attempted. These results demonstrated that the combination of HPLC and chemometrics offers a feasible and efficient approach for quality evaluation of citrus fruits and beverages.
