Background: Achillea tenuifolia Lam. (Compositae) with small yellow flowers and several times pinnately divided leaves in worm shape is known for many years in the folk medicine. It has been used to reduce sweating and to stop bleeding. It helps regulation of the menstrual cycle and reduces heavy bleeding and pain. Materials and Methods: Plant material (flower, leaf and stem) was collected in...

background and aims: the achillea genus has a wide distributional range, and the differences in oil composition may be affected by different environmental factors such as plant genetic type, seasonality, and developmental stage. the aim of this research was to determine the chemical combination of the essential oils derived from flowering aerial parts of achillea millefolium, a. biebersteinii a...

Essential oils from plants used in traditional medicine are known as a rich source of chemically diverse compounds with specific biological activities. Achillea millefolium essential oil (AEO) was screened for vitro activity against Babesia canis. The AEO obtained by hydrodistillation and analysed gas chromatography coupled to mass spectrometry (GC-MS). GC-MS revealed the presence 47 oil. Those...

Oxidative stability of chia seed oil enriched with oregano (Origanum vulgare L.) and yarrow (Achillea millefolium) extracts at different concentrations (600, 1200, 1800 ppm) was evaluated under accelerated oxidation conditions for 5 days. The total phenolic compounds antioxidant activity extract were higher than the extract. With decreasing increasing time, oxidative decreased significantly ( <...

This study evaluated the influence of seasonal variation on the yield and composition of essential oil of Lippia origanoides occurring in the Middle Rio Amazonas, Brazil, and the impact on its antimicrobial potential. The average oil yield was 1.7% ± 0.2% in the rainy season and 1.6% ± 0.3% in the dry season. Some correlations with climatic parameters were observed. The major components were ca...

Rates of hydrocarbon biodegradation were estimated by following oxygen uptake during mineral oil oxidation or oxidation of [1-14C]hexadecane to 14CO2, when these substrates were added to natural water samples from Wisconsin lakes. A lag phase preceded hydrocarbon oxidation, the length of which depended on population density or on factors influencing growth rate and on the presence of nonhydroca...
