Abstract
GOVINDAN and GOVINDAN, Department of Chemistry, Fitchburg State College, Fitchburg, MA 01420, USA, mgovindan@fsc.edu, evaluated the usefulness of thin-layer chromatography (TLC) as a method of determining the quality of the herbal product goldenseal (Hydrastis canadensis) .
Background
Goldenseal is one of the top five herbal supplements in the international market.
Methodology
10 goldenseal samples were analysed by TLC using two solvent systems and spray reagents.
Results
Five samples contained both hydrastine and berberine, four contained berberine only, and one did not contain either of these alkaloids. The TLC results were confirmed by high-pressure liquid chromatography (HPLC).
Conclusion
TLC is a convenient method of determining the quality and possible adulteration of goldenseal products.
