In the 70s, reports began to appear of phenolic metabolites of brown algae with the characteristics of tannins; these compounds, initially termed phaeophyte tannins, marine algal polyphenols or polyphloroglucinols, are known as phlorotannins, the youngest group of plant polyphenolics. Despite over 40 years of research in phlorotannins, this area is still in the exponential growth phase; however...

Lipophilicity (logP) represents one of the most studied and most frequently used fundamental physicochemical properties. At present there are several possibilities for its quantitative expression and many of them stems from chromatographic experiments. Numerous attempts have been made to compare different computational methods, chromatographic methods vs. computational approaches, as well as ch...

The newest results in the chromatographic analysis of pesrticides present in foods and food products are collected and the results are critically evaluated. Examples for the employment of preconcentration and prepurification technologies, gas chromatography using ECD, NPD, MS and MS/MS detection methods, liquid chromatographic methodologies such as thin-layer chromatography, high performance li...
