Berberine is a quaternary ammonium salt from the group of isoquinoline alkaloids. It is found in such plants as Berberis, goldenseal (Hydrastis canadensis), and Coptis chinensis, usually in the roots, rhizomes, stems, and bark. Berberine is strongly yellow colored, which is why in earlier times berberis species were used to dye wool, leather and wood. Wool is still today dyed with berberine in Northern India. Under ultraviolet light, berberine shows a strong yellow fluorescence. Because of this it is used in histology for staining heparin in mast cells. As a natural dye berberin has a Colour Index (CI) of 75160.
