| Study ID | ST000508 |
| Study Title | Metabolic Profiling of Date Palm Fruits |
| Study Summary | In this study, two independent large cohorts of mature dates exhibiting substantial diversity in origin, varieties and fruit processing conditions were measured by metabolomics techniques in order to identify major determinants of the fruit metabotype. Additional samples reflecting different stages of date fruit ripening process has been included for 10 different fruit varieties. |

| Chromatography Summary: | The 5% diphenyl/ 95% dimethyl polysiloxane GC column and the temperature ramp was from 40° to 300° C in a 16 minute period. Samples were analyzed on a Thermo-Finnigan Trace DSQ fast-scanning single-quadrupole mass spectrometer using electron impact ionization. The instrument was tuned and calibrated for mass resolution and mass accuracy on a daily basis. |

| Chromatography ID: | CH000558 |
| Chromatography Summary: | The LC/MS portion of the platform was based on a Waters ACQUITY ultra-performance liquid chromatography (UPLC) and a ThermoFisher Scientific Orbitrap Elite high resolution/accurate mass spectrometer, which consisted of a heated electrospray ionization (HESI) source and orbitrap mass analyzer operated at 30,000 mass resolution. The MS analysis alternated between MS and data-dependent MS2 scans using dynamic exclusion. |
