Abstract

During the Belle Epoque, the use of cocaine, well known to the South American populations, spread among the European elite in the form of a tonic drink created from coca leaves macerated in Bordeaux wine, the Mariani wine. Nowadays, bottles in circulation are extremely rare but the investigations of a Parisian historian led him to the discovery of a bottle of wine that belonged to Angelo Mariani's estate at the end of the 19th century. Our laboratory was asked to analyse the contents of the bottle in order to search for the main active compounds and to estimate the state of preservation. The analysis of the centenarian product collected was aimed at identifying the alcohols and solvents by HS-GC/FID and HS-GC/MS after dilution in water, and the main alkaloids contained in all the samples by LC-HRMS screening and LC-MS/MS quantification. The Mariani wine presented an alcohol content of 15.7°. The screening and the subsequent dosage revealed the following substances: cocaine (86 ng/mL), benzoylecgonine (383 ng/mL), cocaethylene (17 ng/mL), ecgonine methyl ester (130 ng/mL), caffeine, cuscohygrine, cinnamoylcocaine and synephrine. The alkaloids found in the Mariani wine confirm the real presence of coca leaves in this drink. Their low concentrations may indicate drug instability. The presence of cocaethylene demonstrates that it can be formed without passing through the liver, which was supposed to be the site of production when cocaine and ethanol are present in the body at the same time. These appear to be the first report in the literature presenting the analysis of Mariani wine with the dosage of cocaine derivatives.
