Allium Cepae Extract
Total polyphenol and main flavonoid antioxidants in different onion (Allium cepa L.) varieties.
In onion, spiraeoside (quercetin-4'-O-β-D-glucoside), rutin and quercetin and 3 other not identified compounds were found as the major constituents. Significant cultivar differences were found. The most abundant compound was spiraeoside (32 234 mg/kg DM in red onion, 23 283 mg/kg DM in yellow onion and 265 mg/kg DM in white onion).
During storage, an increase in flavonoids could be observed, especially at a laboratory temperature co***red to storage at a lower temperature.
