Sample Preparation for Metabolomics Study For the GC/MS analysis, myocardial tissue samples were subjected to pretreatment, extraction, and derivatization as previously reported ( Identification of metabolites was carried out through comparison of the mass spectra (MS) and the retention indices of the detected compounds with the reference standards and those from the databases below: Wiley 9 (WileyVCH Verlag GmbH & Co
Additional antioxidants like ascorbic acid (vitamin C) help release the NO that was bound to glutathione, recapturing the NO that the body has already produced.[52] This may be one mechanism by which antioxidants and natural substances like pomegranate and quercetinwhich provide high levels of polyphenols, which are natural antioxidantsalso have a positive effect on ED of a vascular etiology.[53],[54],[55] Antioxidants are also important for the formation of the NOS enzyme as well as maintaining it in its active, coupled state.[56],[57] When NOS becomes uncoupled, it reduces molecular oxygen to superoxide (a damaging free radical) instead of NO.[58] This may be one means by which the French Maritime pine bark [CD2] also has a positive impact on erectile function
