Metabolite profiling and biological activity are reported from organic and aqueous extracts of the fruit from the desert palm Hyphaene thebaica. Phenolics and oxylipids profiles were determined using UPLC-PDA-TOF (ultra performance-photodiode array-time of flight) high-resolution mass spectrometry in order to obtain the molecular formula and exact mass Under optimized conditions, 17 compounds were simultaneously identified and quantified including 2 cinnamic acid derivatives, 5 flavonoids, 6 fatty acids, 2 sphingolipids, a lignan, and a stilbene. Sugars composition in the fruit was characterized and quantified by H-1-NMR (nuclear magnetic resonance) with sucrose detected as the major component in fruit at a level of 219 mg/g. Fruit organic extracts anti-inflammatory potential was assessed in vitro by cyclooxygenase-1 enzyme inhibition.
