The purpose of this study was to analyze the  Foeniculum vulgare  Mill. collection by the content and component composition of essential oil. The study was carried out in 2017-2019. The collection is located in the experimental site of the Research Institute of Agriculture of Crimea, located in the Crimea Foothill (Krymskaya Roza village) in accordance with the developed methods. The component composition of  F. vulgare  essential oil was determined by the method of gas chromatography on the “Crystal 5000.2”. It was found that the essential oil content in mature  F. vulgare  fruits amounted to the average of 5,88± 0.10%, which was higher than in the green plants’ material - 2,36± 0.06%. The main component of the essential oil is anethole. The anethole content in essential oil from fruits was higher than from the green plants’ material: 64.9-84.3% and 33.5-74.6%, respectively. 66.0% of the analyzed samples corresponded to ISO 17412:2007 requirements. Essential oil from the green plants’ material contained more α-phellandrene compared to essential oil from fruits: 1.5-19.9% and 0.1-0.4%, respectively. According to the research results, 9 promising samples with a high content of essential oil in fruits - from 6,52 ± 0.88 to 8,10± 0.91% were distinguished.
