| Résumé : |
This master's thesis focuses on the extraction of essential oils from three aromatic and medicinal plants, using two methods. In our work, we aimed to study the effect of extraction method on the quality and weight yield of EOs. In fact, the results indicate that essential oils extracted from, Rosmarinus officinalis L., Eucalyptus globulus Labill. and Citrus sinensis were compatible with those of previous studies, reported in literature. All essential oils were extracted using Clevenger-type apparatus and simple hydrodistillation. The findings of this research provide valuable insights into the extraction methods and properties of essential oils derived from rosemary and eucalyptus leaves and orange peels. Furthermore, the integration of these essential oils in soap production highlights their potential as natural additives, offering fragrance and potential therapeutic benefits. |
