Two Methods of Determining Total Phenolic Content of Foods and Juices in a General, Organic, and Biological (GOB) Chemistry Lab

Autor: Sam H. Leung, Lee Alan Shaver, Amy Puderbaugh, Stephen A. Angel

Publikováno v: Journal of Chemical Education. 88:492-495

The determination of total phenolics in foods and fruit juices was used successfully as a laboratory experiment in our undergraduate general, organic, and biological (GOB) chemistry course. Two different colorimetric methods were used over three year

Publikováno v: Journal of Coordination Chemistry. 60:1809-1816

The use of COSzY and NOESY 1H NMR techniques allows for the assignment of 1H NMR chemical shifts for the bis(2,2′-bipyridine)carbonatocobalt(III) ion. These assignments are further confirmed by DFT GIAO-NMR calculations using the model chemistry B3
