Metabolite profiling is one of the most challenging fields in applied mass spectrometry. Mass spectrometry was used to characterize the metabolites of propranolol, a beta-adrenergic receptor antagonist containing numerous oxidation sites. Propranolol is extensively metabolized, with most metabolites

Abstract
The metabolic profile of polar (methanol) and non‐polar (hexane) extracts of Curcuma domestica, a widely used medicinal plant, was established using various different analytical techniques, including GC‐FID, GC‐MS, HR‐GC‐MS and analytical HPLC‐ESI‐MS/MS by means of LTQ‐Orbitrap technology. The major non‐volatile curcuminoids curcumin, demethoxycurcumin and bisdemethoxycurcumin were identified when their chromatographic and precursor ion masses were compared with those of authentic standard compounds. In this paper we describe for the first time a GC/MS‐based method for metabolic profiling of the hydrophilic extract. We also identified 61 polar metabolites as TMS derivatives.
