Chemical profile and biological activities of root oil from Vetiveria zizanioides (L.) Nash

Vetiveria zizanioides (L.) Nash (Chrysopogon zizanioides (L.) Roberty syn.), is a perennial plant of the family Poaceae (subfamily Panicoideae), native to India and widely found in Asia, Africa, Central and South America. Vetiver essential oil was described as a viscous liquid with low volatility, diverse colour from pale yellow to dark brown, as well as a deep and woody odour. Vetiver oil is commonly used as a main odour contributor in the perfumery industry, and also can be beneficial in the food industry as a flavouring agent. The root essential oil possesses various functional properties, such as antioxidant, antibacterial and anti- inflammatory properties, with applications in aromatherapy. Due to various properties, current studies have focused on the optimisation of vetiver oil extraction techniques in order to reduce production costs, solving problems related to environmental pollution, and the exhaustive characterisation of its chemical profile, using different chromatographic methods.

The aim of the project is to evaluate the bioactivities, especially antimicrobial, antioxidant and anti- inflammatory of vetiver oil obtained by different extraction techniques, to determine if the non- conventional extraction methods can have an impact on the extraction yield and biological properties of the oil. Moreover, it is necessary to use advanced and suitable analytical techniques, due to the fact that conventional chromatographic methods are no longer being used as the only chromatographic technique for vetiver essential oil because of its chemical complexity.
