Abstract Scopoletin is a phytochemical of coumarins distributed in some plants. The aim this study was the evaluation scopoletin content and antioxidant activity nettle, mallow, purslane, knot-grass, dill coriander encountered Black Sea regions. Analyses were conducted on leaves stems these plants, except knot-grass. lowest found nettle (11.48 mg/kg) highest amount knot-grass (6708.37 mg/kg). n...

Choline acetyltransferase was demonstrated in nettles (Urtica dioica), peas (Pisum sativum), spinach (Spinacia oleracea), sunflower (Helianthus annuus) and blue--green algae by using a Sepharose--CoASH affinity column. The column effected a 1500-fold purification of the enzyme from nettle homogenates and was required for demonstrating activity in the other higher plants. Demonstration of the en...

Levels of Fe, Mn, Cu, Zn, Mo, Co, Ni, Se, Sn and Al were determined in 14 medicinal plants from Serbia, which are widely used in phytopharmacy as herbal teas. The following plants were investigated: yarrow (Achillea millefolium L.), basil (Ocimum hasilicum L.), St. John's wort (Hypericum perforatum L.), peppermint (Mentha x piperita L.), field horsetail (Equisetum arvense L.), stinging nettle (...

a total of 288 broiler chickens (1 d old) were used in a 42-d growth trial to study the effects of chicory (cichorium intybus) and nettle (urtica dioica) with or without multi-enzyme on growth performance, carcass traits, and biochemical parameters. the corn-soybean based control diet and 8 experimental diets were fed to each of 3 pens of chickens (12 chickens/pen). treatments were as follows: ...

A major challenge for researchers and educators has been to discern the effect of ICT use on student learning outcomes. This paper maps the achievements in Year 10 Science of two cohorts of students over two years where students in the first year studied in a traditional environment while students in the second took part in a blended or e-learning environment. Using both quantitative and qualit...
