Quality Assessment of Eucalyptus Oils Available in Nairobi County, Kenya

Abstract

This study assessed eucalyptus oil quality in Nairobi County, Kenya, a product that garnered global attention during the COVID-19  pandemic. Twelve Eucalyptus oil product samples were obtained from local retailers encompassing community pharmacies,  supermarkets and health shops. Gas chromatography was utilized for the identification and assay of the primary component, Eucalyptol.  Additionally, an evaluation of product attributes, including optical rotation, refractive index, and relative density, was performed on the  samples. The examination also extended to product labels and packaging to ensure conformity with established standards. Seven  samples adhered to the stipulated labelling and packaging criteria, while two failed the refractive index test, and nine did not meet the  relative density specifications. All samples met the optical rotation acceptance criteria. Only one sample conformed to the prescribed  content specifications. These findings shed light on the quality of eucalyptus oils and have public health and regulatory implications,   particularly given their increased use during the COVID-19 pandemic.
