[99] Cyanidin-3glucoside (red kernel color, RKC) Beverages UHPLC-ESI-TOF-MS/ MS Study of their degradation and a new component was identified when RKC degraded under various pH conditions and a degradation pathway is proposed. The results will assist in understanding the degradation mechanism of the colorant Cyd-3-Glu.

[101] Natural Toxins Mycotoxins Herbal medicine UHPLC-QqTOF-MS Mass range m/z 50–1000 MSE (two full scan functions at low and high collision energy) Each of the accurate masses of the markers obtained was searched in a mycotoxins/fungal metabolites database.

Efforts must also be made regarding the instrumental phase to overcome sensitivity/selectivity limits and interferences. For this purpose, high-resolution full-scan analysis in MS is an interesting alternative to the traditional tandem approach. Modern HRMS instruments can be operated at resolutions up to R = 240,000 using Orbitrap technology with mass accuracy <5 ppm in full-scan mode. Another advantage of HRMS is that the acquired data can even be evaluated retrospectively for additional compounds or reprocessing of raw data by another compound class database.
