Thermo Fisher Scientific is pleased to announce
a new method that uses
high-performance liquid chromatography (HPLC)
combined with
charged aerosol detection (CAD) to enable
improved quantitation of triterpene content in gotu kola. Low-wavelength UV detection
commonly used for triterpene analysis often results in strongly sloping
baselines, and interferences from minor components can adversely affect
quantitation. Customer Application Note (CAN) 111:
Determination of Triterpenes in Centella asiatica (Gotu Kola) by HPLC-CAD demonstrates
that charged aerosol detection minimizes these interferences and improves the
baseline, thereby enabling improved quantitation of triterpenes in gotu kola.
Gota kola is a small herbaceous annual plant
used as a medicinal herb in Ayurvedic medicine and used in traditional Chinese
medicine to treat a wide variety of conditions including improvement of memory
and blood flow. Gota kola is also used as a topical application for skin
conditions such as ulcers, wounds, and eczema. The chemical compounds of
interest in gotu kola are usually considered to be the ursane- and
oleanane-type triterpenes and the triterpene glycosides including asiaticoside,
madecassoside (asiaticoside A), asiaticoside B, madecassic acid, asiatic acid,
and terminolic acid.
