Perilla is the genus of herbaceous plants of Lamiaceae family. The essential oil of Perilla is believed to be essential part of the herb. It was claimed to have anti-inflammatory, anti-hyperlipidemia, antioxidative and antimicrobial activities. Apart from pharmaceutical and nutrition purposes, It is an edible plant frequently used as a fresh vegetable. It was also applied to produce perfume and cosmetics. Due to the importance of the essential oil from the P. nanakinensis and the lack of detailed studies of them, our work aimed investigation of contents of essential compositions by GC- TOF/MS method. The materials of the study were the aerial parts of P. nankinesis collected at full flowering stage, Guria Region, Georgia. A qualitative analysis of the individual compounds in P. nankinensis essential oil performed by gas chromatography (GC) coupled with time-of-flight mass spectrometer (TOF/MS) for the identification of the resolved peaks. 28 components, which accounted for 77,7% of the oil, were identified. The main components of this essential oil were 1,3,6,10-Dodecatetraene, 3,7,11-trimethyl-, (Z,E)- (α-Farnesene) (34.3%), Caryophyllene oxide (10.2%), 1,6-Octadien-3-ol, 3,7-dimethyl- (linalool) (10.2%). Essential oil also contained humulene (3.9%),caryophyllene (1.9%), methyl salicilate (1.15%), 2-hexanoylfuran (1.0%), gernacrene (1.1%). Based on the results of our experimental data and literature reviews, Perilla essential oil can represent special interest and can be used as an important natural substance for obtaining medicinal and preventive products with the several biological activities.
