| Abstract | The objective of this study was to evaluate total phenolic content (TPC), total anthocyanin content (TAC), antioxidantactivities (AOA) and identify the components of phenolic and anthocyanin in each type of purple waxy corn (PWC) waste,including tassel, cob, kernel pericarp and silk. The results revealed that the silk had the greatest amount of TPC related to thehighest AOA, while the cob had the highest TAC. Cyanidin-3-glucoside was the dominant anthocyanin in PWC, followed bypeonidin-3-glucoside and pelargonidin-3-glucoside in rank order. Protocatechuic acid was the most abundant phenolic compoundin kernel pericarp and silk, while rutin was the dominant component detected in tassel and cob. Additionally, hydroxybenzoic,vanillic, caffeic, syringic, p-coumaric, ferulic and sinapic acid as well as quercetin and kaempferol were also detected in differentparts of PWC. |
