High-performance liquid chromatography interfaced with thermospray mass spectrometry is described for the identification of various flavonol glycosides from Ginkgo biloba, Calendula officinalis and Tilia cordata. Thermospray ionization gave parent species with few and diagnostic fragment ions, thus allowing structure elucidation as well as discrimination between different glycosylation sites.

Abstract
High-performance liquid chromatography interfaced with thermospray mass spectrometry is described for the identification of various flavonol glycosides from Ginkgo biloba, Calendula officinalis and Tilia cordata. Thermospray ionization gave parent species with few and diagnostic fragment ions, thus allowing structure elucidation as well as discrimination between different glycosylation sites.
