Abstract
Essential oils are highly appreciated raw materials due to a variety of their intrinsic characteristics and properties. They are complex mixtures of volatile compounds produced by plants as secondary metabolites; communicational and defence roles were attributed to constituents of essential oils [1]. Over the years, many researchers have reported a great variety of properties of essential oils including antimicrobial and antioxidant activities, as well as, some other effects of biological interest that could be used in human and veterinary medicine [2].

We reported the occurrence in the market of adulterated clove essential oil, and the adulterant was benzyl alcohol [3]
The technique considered the gold standard for the quality control of essential oils is gas chromatography (GC), ideally, coupled to mass spectrometry (MS)
Summary
Essential oils are highly appreciated raw materials due to a variety of their intrinsic characteristics and properties. Many researchers have reported a great variety of properties of essential oils including antimicrobial and antioxidant activities, as well as, some other effects of biological interest that could be used in human and veterinary medicine [2]. Considering the high demand and the highly appreciated properties of some essential oils, for example, those extracted from lavender or frankincense, there is no wonder that counterfeit and adulterated essential oils can be offered in the market.
