| Study Title | Metabolomics Analysis of Blood Plasma and Stool from Six Week Flaxseed Dietary Intervention in Postmenopausal Women (Serum/GC) |
| Study Summary | Samples were taken before and after 6 weeks of flaxseed dietary intervention. Serum and fecal metabolomics were performed to characterize the metabolomic profiles of serum and stool metabolites pre- and post-intervention. |

| MS Comments: | Gas Chromatography conditions: A 30 m long, 0.25 mm i.d. Rtx-5Sil MS column (0.25 μm 95% dimethyl 5% diphenyl polysiloxane film) with additional 10 m integrated guard column is used (Restek, Bellefonte PA). 99.9999% pure Helium with built-in purifier (Airgas, Radnor PA) is set at constant flow of 1 ml/min. The oven temperature is held constant at 50°C for 1 min and then ramped at 20°C/min to 330°C at which it is held constant for 5 min. Mass spectrometer settings: A Leco Pegasus IV time of flight mass spectrometer is controlled by the Leco ChromaTOF software vs. 2.32 (St. Joseph, MI). The transfer line temperature between gas chromatograph and mass spectrometer is set to 280°C. Electron impact ionization at 70V is employed with an ion source temperature of 250°C. Acquisition rate is 17 spectra/second, with a scan mass range of 85-500 Da. |
