The in vitro antioxidant and antimicrobial activities of the essential oil and methanolic extract of Achillea sieheana Staf. (Asteraceae) were investigated in this study. The chemical composition of the essential oil isolated by hydro-distillation from the aerial parts of A. sieheana was analyzed by
Achillea millefolium L. is a plant widely used in traditional medicine. Nowadays, there is a growing concern about the study of its bioactive properties in order to develop food and nutraceutical formulations. Supercritical anti-solvent fractionation (SAF) of an A. millefollium extract was carried
Variations in the essential oil composition of Achillea millefolium L. growing in Estonia and in other European countries, were determined. The oils were obtained in yields of 0.9-9.5 mL kg-1. A total of 102 components were identified. The quantitatively most important components of yarrow were
Essential oils obtained by steam distillation from the aerial parts of Achillea fragrantissima (Forssk.) Sch. Bip. and the flower, leaf and stem of A. santolina L. as well as their lipophilic constituents obtained by solvent extraction were analysed using GLC and GLC-mass spectrometry. Nineteen
Achillea millefolium L. is a member of the Asteraceae family and has been used in folk medicine in many countries. In this study, 19 compounds in A. millefolium essential oil (AM-EO) have been identified; the major components are artemisia ketone (14.92%), camphor (11.64%), linalyl acetate (11.51%)
Four Achillea species, A. millefolium, A. nobilis, A. eriophora and A. biebersteinii, were grown in small field plots in Iran and harvested at four developmental stages: vegetative, at the appearance of the first flower heads, at full flowering, and at late flowering. The composition of the main
Representatives of the Achillea genus are widely used as foods or nutraceuticals. Considering the increasing demand for herbal dietary supplements with health promoting effects, the objective of this research was to evaluate the chemical composition and biological activities of the essential oils
In phytochemical and chemotaxonomic research work mass spectrometry plays an outstandingly important role. Using gas chromatography/mass spectrometry (GC/MS) we established the chemotaxa of Tanacetum vulgare L. Chemotypes with essential oils containing 60-90% of artemisia ketone, carveol,
