Using GC-MS Technology to Identify the Compounds Resulting from Mixing of Alcoholic Extracts of Some Medicinal Plants

Phytochemicals are considered as one of the most important pharmaceutical compounds used in pharmacy at all, due to their high therapeutic efficacy and few side effects compared with chemically prepared drugs. On the other hand, the modern techniques of analysis such as GC-MS made it easier to know the chemicals that make up the materials to be studied. In our study, alcoholic extracts of (Punica granatum peel, Ziziphusspina-christi leaves, and Eucalyptus camaldulensis leaves) were prepared, in addition to prepare the mixtures of these extracts by mixing the equal proportions of two extracts only of three plant extracts each time. The result was 3 pure extracts and 3 mixture extracts. After that, these samples were analyzed with the GC-MS device, and the results of the analysis were compared with each other to find out the structural differences occurred after mixing. The results proved the presence of new chemical compounds in the mixture extracts completely different from the chemical compounds found in the pure compounds, whether in terms of chemical composition or biological activity.
