Barbiturates are derivatives of barbituric acid. They act as central nervous depressants. These drugs are frequently used as sedatives or anesthetics. It is a simple and reproducible method for the analysis of barbiturates.

Usage of these drugs is increased in recent days and the analysis of barbiturates by GC/MS is very fast. As they are used as sedatives their usage has been increased to relieve the stress. But the over usage of these drugs may lead to death. Different barbiturates like phenobarbital, pentobarbital can be analyzed by their molecular weights. Because of the over usage of the drugs the interest to analyze them has been enhanced in order to know the characteristics.
