Abstract
Benzodiazepine (BDZ)-like compounds, present in trace amounts in normal subjects increase in the blood of liver cirrhotic patients. The origin of these compounds is still unknown but they are present in medicinal plants and foods. Herein we report the detection of BDZ-like molecules in fruits, vegetables, cereals, meat, milk and cheeses and in different cultivars of potatoes, tomatoes and carrots. The extracted food was separated by HPLC purification and the collected fractions were tested by radioreceptor binding assay in order to evaluate their ability to selectively bind the central benzodiazepine receptors. The mean value was 14.80 ng of diazepam equivalent (DE)/g in fruits, 4.34 ng DE/g in vegetables, 6.35 in cereals and 4.09 in meat. BDZ-like compounds are poorly present in cheeses and completely absent in olive and seeds oil. From these findings it is possible to select food with low amount of BDZ-like molecules useful for cirrhotic diet in order to prevent hepatic encephalopathy.Pubblicazioni consigliate
