Plants are the most important source of biological compounds that used to achieve activity. The originating crude extracts plants is broadly as therapeutic drugs treat various infectious damages. present study was arranged investigate potential Alkanna tinctoria Tausch, roots extract, collected from district Bannu, Pakistan in contradiction human pathogenic infections, resistant and antioxidant...

Alkannin is the main coloring matter of Alkanet, a natural red dye extracted from root Alkanna tinctoria L. Shikonin, optical isomer alkannin, Lithospermum erythrorhizon. As both dyes are only slightly soluble in water, application ordinary Raman spectroscopy limited. Thus, Surface-enhanced (SERS) can be successfully applied to study solutions. Solid alkannin and shikonin were characterized by ...

In this work, dyeing properties of wool samples with Alkanna tinctorum root extract was investigated. For purpose, two different dyestuff extracts, red and blue are gained from its roots acetone ethanol solvents, as well. Wool fabrics (194 pieces) dyed AIK(SO4)·12H2O, FeSO4·7H2O, CuSO4·5H2O, AgNO3 CoCI2·6H2O mordants at pH 2, 4, 6 8, respectively. Unmordanting, pre-mordanting, meta-mordanting, ...
