Characterizing Phenolic Compounds in Fava Beans
Fava beans are a good source of polyphenols and are located in different parts of the plant. Phenolic compounds are thought to contribute to the overall antioxidant activities of plant foods. However, there is a lack of information on the phenolic composition of the seeds (beans) of some edible varieties. This has led a team of researchers based in Chile and Spain to use high performance liquid chromatography (HPLC) to identify the composition of a variety of immature fava seeds. More... |

Recent Developments in Protein Glycosylation Analysis by HPLC with Charged Aerosol and Mass Spectrometric Detection
Tuesday, September 17, 2013
8:00 am PDT/ 11:00 am EDT/ 16:00 BST/ 17:00 CEDT.
This web seminar will discuss promising improvements to glycosylation analysis that couple unique HPLC stationary phases with direct measurement of glycans by charged aerosol detection and with flow-splitting for simultaneous mass spectrometry MS-MS detection. These strategies avoid problematic O-linked glycan degradation (“peeling”) associated with some other quantitative methods, and employs optimal conditions for heightened characterization using additional offline MS techniques for characterization. |
