Previous studies of propofol (2,6-diisopropylphenol) pharmacology have shown that this widely used anaesthetic drug is extensively cleared from the body by conjugation of the parent molecule or its quinol metabolite. On the basis of potential influen

The aim of this work was to study the influence of labelling on caffeine metabolism according to the incubation mode. It has been observed that labelling induces an isotopic effect on metabolisation speed: apparent half-lives are systematically incre

Saffron is one of the most expensive spices. Consequently, it is not so difficult to understand that fraudulent saffron exists. Thus, it was interesting to study the most important flavouring component, in terms of aroma, volatile compound of saffron
