“…Vitamin C is mainly ingested as ascorbic acid (the major form in plants) but also as dehydroascorbic acid (oxidized form). The four Polygonaceae species R. ulmifolius (Barros et al, 2010e;Pereira et al, 2013), R. induratus (Pereira et al, 2011;Pinela et al, 2016c), R. acetosella (Pereira et al, , 2011 and R. papillaris (Morales et al, 2014;Sánchez-Mata et al, 2012), the wild asparagus T. communis and A. acutifolius (Martins et al, 2011;Pereira et al, 2013;Sánchez-Mata et al, 2012), P. oleracea (Petropoulos et al, 2016(Petropoulos et al, , 2015, H. stoechas (Barros et al, 2010e;Pereira et al, 2013) and M. sylvestris flowers (Barros et al, 2010a) were reported as having a high content of ascorbic acid (Table 6). Based on the mean values of this vitamin, it is possible to conclude that a 100-g portion of these WEPs is sufficient to provide more than 30% of the RDA of vitamin C for male and/or female individuals with 19 or more years old (Table A1).…”
