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...

In this research, supercritical CO2 extraction is applied to extract bioactive compounds from Lamium album (white dead nettle, Lamiaceae). Extraction was performed at various temperatures (40, 50, and 60 °C) using methanol as co-solvent a constant flow rate of CO2, methanol, pressure. The collected extracts were characterized in terms antioxidant capacity by DPPH, ABTS FRAP vitro activity assay...

Conventional methods for extraction of the active constituents from herbal plants, in addition to their high processing costs, are harmful to the environment owing to their time and energy consumption, uncontrollable parameters, use of toxic and dangerous solvents, loss of the extract, thermal instability, the contamination of the product with organic solvents and the loss of water-soluble comp...

Increasing public concerns about fungicide residues have prompted interests in biological control especially use of herb extracts derived from several medicinal plants as an alternative strategy for disease management. Recently tomato leaf spot disease caused by Alternaria alternata has become epidemic in almost areas of Iran. This study was conducted for the identification of the effect of ant...

Crop yields and root growth were studied in a 6-year trial comparing conventional, organic, and biodynamic methods of fertilization. Intense use of a set of biodynamic preparations, including a nettlecontaining compound preparation, was found to have a balancing effect on the yields of maize and winter wheat. This effect may have been caused by greater root growth and improved root health. Intr...

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...

conclusions acute administration of u. dioica impairs the object-recognition task if it is used only before the training session. this may be due to its modulation on the acquisition processing of object-recognition. u. dioica has no significant effects on the consolidation or retrieval processing stages of the nor task. these results emphasize the unfavorable effect on cognitive function of pr...

Introduction: Stinging nettle (Urtica dioica L.) is the most important genus in the plant family Urticaceae. Urtica Dioica root Extract (UDE) is widely used for the treatment of prostate hyperplasia. Side effects of UDE were not studied on other organs such as testes (an important organ of the male reproductive system). Furthermore, antagonist effects of UDE on testosterone were considered. The...
