The aim of the present study is the determination of the chemical composition of Vitex agnus-castus fruits essential oils growing wild in two different zones of Albania. Vitex agnus-castus L. (Verbenaceae) is a small tree or deciduous shrub, native to the Mediterranean region and Asia. It is known in Albania as “ konopicë ” and grows wild in the western lowland. The GC/FID and GC/MS analyses of the fruit soils revealed that the major constituents identified were sabinene from 8.98% (Tepelena) to 16.41% (Divjaka); 1,8 cineole from 9.38% (Tepelena) to 12.63% (Divjaka); ß-caryophyllene from 7.88% (Divjaka) to 10.97% (Tepelena); ß-farnesene from 9.23% (Tepelena) to 10.84% (Divjaka); α-terpinyl acetate from 3.64% (Divjaka) to 6.56% (Tepelena) ect.
The major group of components in both areas are the total sesquiterpenes, 34.47% and 33.34%, respectively inDivjaka and Tepelena, with the main rapresentatives β-caryophyllene and β-farnesene. Aromadendrene was found in Divjaka oils with 6.24%, but was not dedected in Tepelena zone. The quantity of the monoterpene hydrocarbons was higher in Divjaka fruits oils, due to the high quantity of sabinene (16.41%). Meanwhile the quantity of total diterpenes was higher in Tepelena oils because of the higher percentage of manoyl oxide. It was also found verticiol in the Tepelena fruits oils which was not detected in Divjaka oils. The examination of the data reveals differences in the chemical composition of Agnus Castus L. fruits essential oils, from two different areas of Albania.
Key words: Vitex agnus-castus, verbenaceae, sabinene, 1,8-cineole, β-pinene, β-farnesene and ß-caryophyllene.
