Medicinal plants play a crucial role in traditional medicine and in the maintenance of human health worldwide. Sesquiterpene lactones represent an interesting group of plant-derived compounds that are currently being tested as lead drugs in cancer clinical trials. Achillea falcata is a medicinal plant indigenous to the Middle Eastern region and belongs to the Asteraceae family, which is known t...

objectives the current research aimed to study achillea millefolium and thymus vulgaris antiviral activity against newcastle disease virus (ndv). materials and methods the antiviral activity of the plants was measured by the reduction assay of viral titer, and explained by inhibition percentage (ip). background nowadays natural products such as pure compounds and plant extract scan provide unli...

the cytotoxic activity of ethanolic extracts of thymus vulgaris, thuja orientalis and achillea millefolium was investigated on various growing tumor cell lines. mtt colorimetric assay was used for measuring the inhibition of cell proliferation. all of the three extracts showed a relatively dose-dependent inhibition of proliferation of human breast cancer (sk-br-3, mda-mb-435) and leukemia (u937...

Invasive species may undergo rapid change as they invade. Native species persisting in invaded areas may also experience rapid change over this short timescale relative to native populations in uninvaded areas. We investigated the response of the native Achillea millefolium to soil from Holcus lanatus-invaded and uninvaded areas, and we sought to determine whether differential responses between...

Thirteen plant extracts, selected for their high ̄avonoid content, were screened on their action on fermentation and protozoa numbers in 1 l dual out ̄ow fermenters supplied with a 50:50 orchard grass hay‡ barley diet. Using a 214ÿ10 fractional factorial design, we tested each extract at the rate of 0.5 g per day. The corresponding organic matter in ̄ow was equal to 3.4% of the basal hexoses ferm...
