What is it about?
Volatile components in the essential oil of basil were identified by gas chromatography/mass spectrometry (GC/MS) with electron ionization (EI) mode. The major volatile components of basil under investigation are α-pinene, sabinene, β-pinene, d-limonene, eucalyptol, l-linalool and estragole. Electron ionization mass spectra of these compounds have been obtained and investigated. Furthermore, the semi-empirical MNDO [Modified Neglect of Diatomic Overlap] method was used to calculate the thermochemical data for the structural properties of these compounds.

Why is it important?
The experimental investigations show that the application of GC-MS can provide a rather detailed analysis of basil leaves by using a good obtained chromatogram and mass spectra. These experimental data together with the theoretical quantum chemical calculations (MNDO) give us more information about the chemical behaviour of the studied molecules which may be important for many chemical and medical applications.
Perspectives
The chemistry and reactivity of medicinal plants such as basil have always been of great interest because of its importance role in the treatments of various kinds of diseases. Knowledge of mass spectrometric fragmentation mechanisms of the volatile components in Basil together with the calculated data obtains by the semi-empirical MNDO method is very important in order to understand the chemical processes that shared in biological systems.
