the present study investigates the antioxidant potential of the ethyl acetate fraction of the aerial parts eclipta alba l. hassk (eaea) which was widely used as hepatoprotective plant. eaea was orally administered at doses of 50, 100 and 200 mg/kg for 7 days in male charles foster rats. the extent of hepatoprotective potential of e . alba was studied by assessing the biochemical parameters like...

Seed germination is considered a critical phase in plant development and relatively sensitive to heavy metals. White poplar (Populus alba) trees tend to accumulate Cd and Zn in their tissues. We tested if soil contamination can affect P. alba progeny, reduced seed germination and explored the distribution of mineral elements in the seed. For this purpose, fruits and seeds from female P. alba tr...

BACKGROUND AND AIMS Populus alba is a thermophilic forest tree present in the Mediterranean basin. Its habitat is highly fragmented and its distribution range has been subject to long-term human interference, resulting in debate surrounding whether certain populations are native or exotic in origin. In particular, populations from the islands of Corsica and Sardinia are of uncertain origin. Whi...
