The component composition of the essential oil from Laurus nobilis L. unripe fruits harvested in Ukraine

Abstract

Aim. To study the qualitative composition and the quantitative content of the essential oil components from Laurus nobilis L. unripe fruits. Results and discussion. In the essential oil from Laurus nobilis L. unripe fruits 31 compounds were determined; among them 28 substances were identified. A high content was characteristic for spatulenol (1947.1 mg/kg) and betulenol (925.3 mg/kg). Experimental part. The raw material for obtaining the essential oil (unripe fruits) of Laurus nobilis L. was harvested in November 2017 in Alushta and the village of Rybalskoe, Crimea. The component composition of the essential oil of the unripe fruits from Laurus nobilis L. was studied and the constituents of the essential oil were identified by chromato-mass spectrometry using an Agilent Technology 6890N chromatograph. The component composition of the essential oil was revealed by comparing the results obtained with data from the NIST 02 mass spectrum library (more than 174.000 substances). Conclusions. The component composition of the essential oil from Laurus nobilis L. unripe fruits harvested in Ukraine has been studied. Taking into account the set of the biologically active compounds found in the essential oil of Laurus nobilis L. it can be argued that further pharmacognostic studies of fruits of this plant as the medicinal raw material with the predicted pharmacological activity (e.g., antimicrobial and skin cleansing) are promising.
