Abstract
Due to its biological qualities and safety for human consumption, sweet lime essential oil is employed in food and pharmaceutical industries. Geographical cultivation site is one strategy for modifying the composition of essential oils, which also broadens the range of their biological effects and enhances their natural sources. In the new reclamation zones, Egyptian government favours the cultivation of a variety of Citrus trees. Therefore, the objective of this study was to assess the leaf, flower and peel essential oils of sweet lime trees which are grown in different locations in order to determine the significance of growing sweet lime trees in those locations for utilizing them in essential oil production. From Egypt’s west, south and north, sweet lime leaves, flowers, and peels were gathered. Hydrodistillation was used to separate the essential oils from various organs at various locations, which were then subjected to gas chromatography and gas chromatography/mass spectroscopy analysis. As a result of varied agricultural sites, collected data indicated that different variations were found in the leaf, flower, and peel essential oils content. The main constituents in leaf, flower, and peel essential oils, respectively, were citronellal (53.8–54.1%), nerol (49.5–53.3%), and limonene (69.3–73.4%). Leaf and flower essential oils mostly contained oxygenated monoterpenes, while peel essential oil primarily contained monoterpene hydrocarbons. With samples collected from the south location, the highest values of the major components and fundamental chemical classes of the essential oil concentrations (%) were noted. In order to enhance the sources of essential oils as a natural product, sweet lime trees should be planted in recently reclaimed lands.
