 "The root produces a fine red colouring material which has been used as a dye in the Mediterranean region since antiquity. The root as a dyestuff is soluble in alcohol, ether, and the oils, but is insoluble in water... In alkali environments the alkanet dye has a blue color, with the color changing again to crimson on addition of an acid."

 "From the roots of Alkanna tinctoria Tausch, the alkannin esters of the following acids were isolated and identified: β,​β-dimethylacrylic acid, β-acetoxy-isovaleric acid, isovaleric acid, and angelic acid. These esteric pigments showed excellent wound healing properties in a clinical study on 72 patients with ulcus cruris."​ \\ "From the roots of Alkanna tinctoria Tausch, the alkannin esters of the following acids were isolated and identified: β,​β-dimethylacrylic acid, β-acetoxy-isovaleric acid, isovaleric acid, and angelic acid.
