DETERMINATION AND IDENTIFICATION OF THE ESSENTIAL OIL OF VOLATILE OIL EXTRACTED FROM THE EUCALYPTUS LEAF OF THE CITRIODORA SPECIES

The antifungal bacterial and essential features of essential oils have been reported in many sources around the world which illustrates the potential role of plant bioactive compounds in the various sciences. The identification of the main components of these natural herbal products can be very effective in the pursuit of research in the various fields of science, In this regard, the present research has been carried out to identify and introduce the main components of eucalyptus of the citriodora species. The volatile oil of young and adult eucalyptus leaves was extracted utilizing a Clevenger apparatus and after injection to the extent necessary to the chromatograph gas, using inhibition time and inhibition index, the essential oil composition was studied. From the decomposition of volatile oil of the young and mature eucalyptus leaves of the citriodora, 11 mixtures were extracted. The composition of the citronella in the volatile oil of mature leaves and young leaves were respectively 65.23% and 77.49% as the main composition of the volatile oil and the amount of compounds such as a-pinene, cineol and linalool were reported in the mature and young leaves' volatile oil.
