The plant's roots contain several polyphenolic compounds, such as 1,3-Dihydroxyanthraquinone (purpuroxanthin), 1,4-Dihydroxyanthraquinone (quinizarin), 1,2,4-Trihydroxyanthraquinone (purpurin) and 1,2-dihydroxyanthraquinone . This last compound gives it its red colour to a textile dye known as Rose madder. It was also used as a colourant ...
They consist of several to many flowers, found at both the ends of branches and in the leaf axils.
