Cytotoxicity and Anti-cancer Activity of the Genus Achillea L

BACKGROUND

The genus Achillea L. is rich in bioactive sesquiterpenes and flavonoids; most of the studied species exhibit several biological activities and are used as emmenagogue, wound healing and analgesic agents. Some species are also used in local folklore medicine.

OBJECTIVE

Following a literature survey, we discuss the anti-cancer properties of Achillea species, taking into consideration ethnopharmacological data on their use in traditional medicine for the treatment of cancer. In addition, we screened extracts and isolated secondary metabolites from A. coarctata for cytotoxicity, upon information based on local traditional medicine. The plant was collected in Kozani (Northern Greece), where it is locally used for treating gastrointestinal disorders, including stomach cancer.

METHODS

A selection of the relevant data was performed through a search in PubMed, Scopus, Google Scholar and Science Direct databases. In addition, extracts and isolated compounds from A. coarctata were tested for their in vitro activity against the human cancer cell lines MCF-7 and HeLa.

CONCLUSION

The genus Achillea L. is a valuable source of bioactive secondary metabolites. The most significant outcome of the investigation of medicinal plants is the documentation and the assessment of the traditional information and its use and perspectives in the light of modern pharmacology.

Essential Oil Chemical Composition and Headspace Volatiles Profile of Achillea coarctata from Serbia

This study reports the essential oil composition and headspace volatiles profile of Achillea coarctata Poir. from Serbia. The inflorescences, stems and leaves, and the aerial parts of A. coarctata were analyzed separately. Germacrene D, α-terpineol and 1,8-cineole were the main constituents of the aerial parts essential oil; 1,8-cineole, cis-cadin-4-en-7-ol and α-terpineol were the most dominant compounds in the inflorescence essential oil, while the most abundant components in the stem and leaf oil were germacrene D, cis-cadin-4-en-7-ol and ledol. The percentages of monoterpenoids and sesquiterpenoids in the aerial parts were the same, while there were differences in distribution of these compound classes in inflorescence and stem and leaf essential oils. The major components of the headspace volatiles were the same for aerial parts, inflorescence and stem and leaves: 1,8-cineole, β-pinene and α-pinene.
