Column liquid chromatography/electrospray ionization-time of flight-mass spectrometry and ultraperformance column liquid chromatography/mass spectrometry methods for the determination of ginkgolides and bilobalide in the leaves of Ginkgo biloba and dietary supplements.

27 Feb 2009 Column liquid chromatography/electrospray ionization-time of flight-mass spectrometry (LC/ESI-TOF-MS) and ultraperformance column liquid chromatographiclMS (UPLC/MS) methods were developed for the determination of 5 terpenelactones in the leaves of ... Read more...

Chemical analysis and quality control of Ginkgo biloba leaves, extracts, and phytopharmaceuticals.

13 Jan 2009 The chemical analysis and quality control of Ginkgo leaves, extracts, phytopharmaceuticals and some herbal supplements is comprehensively reviewed. The review is an update of a similar, earlier review in this journal [T.A. van Beek, J. Chromatogr. A ... Read more...

Determination of the derivative from ginkgolide B.

30 Dec 2007 A new compound decomposed from ginkgolide B(GB) is discovered and identified by MS and UV spectrum. It is the dehydrate of GB, which was named as ginkgolide K before. Differently, it cannot exist independently, but only in equilibrium with GB. It is ... Read more...
