objective(s):one strategy for the treatment of diabetes is inhibition of pancreatic α- amylase. plants contains different chemical constituents with potential for inhibition of α-amylase and hence maybe used as therapeutic. materials and methods: urtica dioica and juglans regia linn were tested for α-amylase inhibition. different concentrations of leaf aqueous extracts were incubated with enzym...

Drought is one of the most brutal environmental factors limiting productivity fruit trees. The search for new and efficient microorganisms from unexplored environments that can be used to mitigate negative effects water stress an interesting alternative alleviate drought experienced by plants. This study aimed determine PGPR inoculation on growth physioecological characteristics walnut (Juglans...

Dyeing properties of different fabric species were investigated using leaf extract Juglans regia L. For this purpose, the cotton and wool fabrics dyed brown napthaquinon colorant extracted from walnut leaves by pre-mordanting, meta-mordanting post-mordanting methods in presence copper sulfate (CuSO4.5H2O), ferrous (FeSO4.7H2O) alum (AIK(SO4)2.12H2O) at medium pH. Color codes determined with Pan...

Walnut oil is a high-value product. Investigation of the variation and main climatic factors affecting oil’s chemical composition vital for breeding quality improvement. Therefore, fatty acid, micronutrients, secondary metabolites compositions contents in walnut were determined three species: Juglans regia L. (common walnut), J. sigillata Dode (iron their hybrids (Juglans × L.), which cultivate...
