... To date, their chemical structure has been thoroughly explored as well as their biological activity. Allium species are rich in phytonutrients, mostly flavonoids and organosulfur compounds which exhibit strong antioxidative, antimicrobial, anti-inflammatory and anticarcinogenic activity (AHIABOR et al., 2016;ALBISHI et al., 2013;ASHRAF et al., 2011;BENEKEBLIA, 2004;BOROWSKA et al., 2013;CHANG et al., 2013;COLINA-COCA et al., 2017;HERMAN-ANTOSIEWICZ and SINGH, 2004;JOHNSON et al., 2016;KAUR et al., 2016;KHAZAEI et al., 2017;KOCA et al., 2016;KUMARI and RANJAN, 2014;KWON et al., 2002;LANZOTTI et al., 2014;LANZOTTI, 2006;LI et al., 2014;MIN KIM et al., 1997;NDOYE FOE et al., 2016;ORTIZ, 2015;PAN et al., 2018;QUINTERO-FABIÁN et al., 2013;SHIN et al., 2013;SULEIMAN and ABDALLAH, 2014;THOMAS et al., 2017;THOMSON and ALI, 2003;YANG et al., 2001b). Many epidemiological studies showed that regular consumption of Allium vegetables can decrease the risk of various diseases such as cardiovascular, respiratory, gastrointestinal diseases and different types of cancer FLEISCHAUER et al., 2000;GONZÁLEZ et al., 2006;GUERCIO et al., 2014;KIM et al., 2018;O'GARA et al., 2000;POURZAND et al., 2016;TURATI et al., 2015TURATI et al., , 2014YOU et al., 1989;ZHOU et al., 2011). ...
