Characteristic constitents

Characteristic constituents

Chemically defined substances that are specific for a medicinal plant and can be used for identification purposes: characteristics constituents.

Consistent quality for products of herbal origin can only be assured if the starting plant materials are defined in a rigorous manner.

Herbal substances are a diverse range of botanical materials including leaves, herbs, roots, seeds, bark etc.
Herbal substances and herbal medicinal products are a complex mixture of phytochemical constituents with natural variations depending on the origin, climatic and growing conditions.

A comprehensive specification must be developed for each herbal  preparation :

   -  A qualitative statement of the botanical source,
   -  A qualitative statement about the organoleptic characters and the macroscopic and microscopic characters,
   - Identification of the characteristic constituents by Chromatographic tests such as TLC- densitometry, HPLC, GC, (constituents with known therapeutic activity, or analytical markers, toxic constituents),
   - Quantitative determination of the composition of the active substance or analytic marker,
  -  Profile and stability of the phytochemical constituents.

The Extrasynthese’s catalogue proposes the product range with HPLC/HPTLC/GC quality. These products have been purified to the highest known level. There are delivered with their chromatographic analysis details.
