Essential oils are mixtures of volatile, lipophilic substances isolated from whole plants or their parts. They are easily moving liquids that refract light, are colorless or light yellow in color and are most often of intense odor, which depends on the chemical composition of the oil. They have been used for antibacterial, antiviral, antimycotic, antiparasitic, antispasmodic, anti-inflammatory and anticancer activities, especially in the pharmaceutical, cosmetic, agricultural and food industries. Hydrosols are aqueous solutions saturated with constituents of essential oil that can be produced as a by-product of the distillation of volatile oils or the distillation of a plant material that does not contain volatile oils. They are mild, non-irritating and harmless compared to the essential oils. They are used in cosmetics as skin tonics and the aqueous phases of creams and masks, and in therapy in the form of dressings, nasal drops, oral and mucosal applications, and in some countries as beverages, flavors or in phytomedicine. A certain amount of dried plant material was used for aqueous distillation using a Clevenger apparatus to isolate essential oils and hydrosols. Then, GC-MS and GC-FID analysis were performed to obtain the correct composition of essential oils and hydrosols. From these results it can be seen that the essential oils are highly non-polar and lipophilic, unlike the more hydrosols, which are more polar, so that their mutual composition differed, although we found common compounds in high proportions (hexadecanoic acid, hexahydrofarnasyl acetone, phytol and heptacosane).
