Antiprotozoal activity of Achillea ptarmica (Asteraceae) and its main alkamide constituents.
In the course of our ongoing screening of plants of the family Asteraceae for antiprotozoal activity, a CH2Cl2-extract from the flowering aerial parts of Achillea ptarmica L. (sneezewort yarrow) was found to be active in vitro against Trypanosoma brucei rhodesiense (IC50 = 0.67 µg/mL) and Plasmodium falciparum (IC50 = 6.6 μg/mL). Bioassay guided fractionation led to the isolation and identifica...
متن کاملExudate flavonoid aglycones in the alpine species of Achillea sect. Ptarmica: Chemosystematics of A. moschata and related species (Compositae-Anthemideae).
In completion of our studies on Achillea exudate flavonoids, 11 alpine species of Achillea sect. Ptarmica were analyzed for their aglycone profiles. The study focuses on species commonly associated with A. moschata. The major flavonoid constituents found in exudates of most taxa were 6-hydroxyflavonol 3,6,4'-trimethyl ethers, except in A. ageratifolia and its subspecies, which are characterized...
متن کاملN-alkylamide profiling of Achillea ptarmica and Achillea millefolium extracts by liquid and gas chromatography–mass spectrometry
Achillea millefolium and Achillea ptarmica are both plants belonging to the Asteracea family and are traditionally used for their medicinal properties. It has already been shown that some N-alkylamides (NAAs) are responsible for these pharmacological actions. Therefore, in the present study, the NAA content of the two plants was analytically characterised. Different extracts were prepared from ...
متن کاملAllelopathic Potential of Achillea biebersteinii Afan. (Asteraceae)
The effects of different concentrations (0, 25, 50, 75 and 100%) of aqueous leachate of Achillea biebersteinii on germination characteristics, seedling growth, photosynthetic pigments and protein contents of pepper (Capsicum annuum L.) were investigated through conducting laboratory and greenhouse experiments. Leachate of A. biebersteinii affected negatively germination percentage, germination ...
متن کاملPalearctic species of the genus Tephritis (Diptera, Tephritidae) associated with plants of the tribe Senecioneae (Asteraceae).
Tephritis arnicae (Linnaeus, 1758) from Europe was the hitherto only Palearctic species of the genus Tephritis known to infest flowerheads of asteraceous plants of the tribe Senecioneae. An additional species with similar biology, Tephritis arsenii, new species, recently discovered in Iran and Armenia is described. It is very similar to T. arnicae in the shape of the aculeus and spermathecae, a...
