Abstract The metabolic effects of an oral supplementation with a Curcuma longa extract, at a dose nutritionally relevant with common human use, on hepatic metabolism in rats fed a high fructose and saturated fatty acid (HFS) diet was evaluated. High-

Seized samples of illegally produced cocaine have a very large variability in composition; a fact that may result in a challenge to their analysis. We demonstrate here a simple and fast method to detect the presence of cocaine in both hydrochloride a

An NMR protocol based on multiple-quantum spectroscopy is presented for an analytical screening of polyphenols in olive oils. Three Italian olive oils with different total polyphenols content were used as study case. A total of 24 compounds were iden
