Essential oils are a mixture of volatile compounds, products of the secondary metabolism of plants. Once these oils are extracted, they can be deteriorated losing their organolpetic and therapeutic properties due to various environmental factors. Exposure to light in aerobic conditions is the main cause of these decomposition and leads to the generation of allergenic compounds responsible for dermatitis, eczemas, among others [1]. These degradations can be caused by reactive oxygen species (ROS) photogenerated from endogenous sensitizers. In this work the photodegradation of the essential oil of oregano (OEO) in presence of vitamin B2 (Riboflavin, Rf) was studied.
