BACKGROUND The common nettle (Urtica dioica L.) is co-associated with willows (Salix spp.) in riparian habitats across Europe. We sampled the widespread nettle psyllid, Trioza urticae (Linné, 1758), from Urtica in willow habitats on a megatransect of Europe from the Aegean to the Arctic Ocean. The aim of this study was to use an unusually widespread insect to assess the influence of geographic ...

Ursolic acid is a triterpenoid compound in the plant kingdom and has important biological functions. In this study, ursolic contents of nine herbs including Anethum graveolens (dill), Camellia sinensis L. (green tea), Lepidium sativum (garden cress), Ocimum basilicum (sweet basil), Petroselinum crispum (parsley), Rosmarinus officinalis (rosemary), Salvia (sage), Thymus vulgaris (thyme) Urtica d...

Objective: A research was carried out to investigate the effects of nettle (Urtica dioica) powder (NP) and essential oil (NE) on performance, blood metabolites, carcass characteristics and antioxidant stability in broiler chicks. Methods: The treatments were T1: control diet, T2: control diet + 5g/kg NP, T3: control diet + 10 g/kg NP, T4: control diet + 5g/kg NE and T5: control diet + ...

Study in uitro on the anticestodal activity of Coleus blu111ei leaves extracts against Hy111e11olepis 111icrosfolll11 was conducted. Leaves of C. blwuci were collected and extracted ·with hexane, chloroform, ethanol and water. Anthelmintic activity was evaluated with an assay using H. 111icrosfolllll in a serial microplate dilution method by determination of mortality time. The parasites were t...

A test system is described, which allows the search for compounds interfering with human sex hormone-binding globulin (SHBG) even in complex plant extracts. The method has been evaluated and applied to Urtica dioica root extracts. The lignan secoisolariciresinol (5) as well as a mixture of isomeric (11 E)-9,10,13-trihydroxy-11-octadecenoic and (10 E)-9,12,13-trihydroxy-10-octadecenoic acids (3 ...
