microwave-assisted hydrodistillation (mahd) method has been compared with hydrodistillation (hd) conventional technique for extraction of essential oil from achillea millefolium. microwave-assisted hydrodistillation were examined at three levels of microwave powers (300, 500, and 700 w) .   obtained results show that   mahd offers important advantages over hd in terms of energy savings and extr...

the selected parts of four medicinal plants, achillea millefolium, hibiscus rosasinensis, linum usitatissimum and pluchea lanceolata were extracted in absolute methanol to determine their analgesic activity. analgesic activity was assessed on intact mice by tail flick latency via the tail immersion method. the analgesic activities of these plant extracts were compared with acetylsalicylic acid ...

The Achillea millefolium aggregate is one of the most diverse polyploid complexes of the Northern hemisphere and has its western Eurasian boundary in the Iberian Peninsula. Four ploidy levels have been detected in A. millefolium, three of which have already been found in Iberia (diploid, hexaploid and octoploid), and a fourth (tetraploid) reported during the preparation of this paper. We collec...

The evolution of increased competitive ability (EICA) hypothesis predicts that escape from intense herbivore damage may enable invasive plants to evolve higher competitive ability in the invasive range. Below-ground root herbivory can have a strong impact on plant performance, and invasive plants often compete with multiple species simultaneously, but experimental approaches in which EICA predi...

Acute, subchronic and chronic effects of the P-9801091 plant mixture extract at a dose of 20 mg/kg body mass were assessed in serum of healthy CBA/HZg mice at 24 hours, 7 days, 3 months and 6 months of treatment (experimental group), and compared with the values obtained in the control group of untreated healthy CBA/HZg mice. The P-9801091 plant mixture extract is an antihyperglycemic preparati...
