Separation of quercetin from a Ginkgo Biloba mother tincture using the PrepChrom C-700

Separation of quercetin from a Ginkgo Bilabo mother tincture

The aim of this application note was to isolate a flavonol, quercetin, from a Ginkgo Biloba mother tincture. The prepurification of the mother tincture was performed on a reversed phase flash column by the means of dry loading. The target compound was identified by its characteristic UV-VIS spectra and the retention time determined by running a standard. Subsequently, the purification of the pre-purified fraction of the target compound was performed with a 10 μm reversed phase prep-HPLC column.
