title: Analytical characterisation of homoeopathic mother tinctures.
abstract: Quality of homoeopathic mother tinctures is assured by the definition of the starting material, the manufacturing process and the analytical characteristics described in the monograph. Traditionally analytical characterisation of the mother tincture comprises appearance, odour, identity, density and dry residue. According to annex I of directive 2001/83/EC an assay is only performed in case of a health hazard due to toxic compounds. The concept of marker substances as usually used in phytotherapy cannot be transferred to mother tinctures without research effort. For example the marker substances echinacoside, apigenin-7-glucoside and rosmarinic acid found in dried underground parts of Echinacea pallida Nutt., dried flower heads of Matricaria recutita L. and dried herb of Pulmonaria officinalis L. cannot be found in homoeopathic mother tinctures prepared from fresh material thereof.
