Tajikistan is a small country located in central Asia which is rich in Aromatic medicinal plants. A large number of locally available plants species are used in the preparation of traditional medicines. However, research on essential oils of medicinal and aromatic plants from Tajikistan is still limited, and only a small number of species have been investigated. In coordination with a chemist from Tajik Academy of Sciences in Dushanbe, six aromatic medicinal plants were collected and their essential oils were extracted for analysis. The targeted plants are Bunium persicum B. Fedtsch., Anethum graveolens L., Galagania frangrantissima Lipsky, Melissa officinalis L., Ocimum basilicum L., and Pelargonium graveolens L'Hér. ex Aiton. They were analyzed by using GC-MS for chemical composition and were tested for biological activity including cytotoxicity, antimicrobial, and brine shrimp lethality. In this study, the composition of targeted essential oils and their biological activities would be present.
