Total polyphenol, total phenolic and antioxidant activities of different peanut (Arachis hypogaea L.) market types by Different Techniques Combined with Chemometrics (PCA and HCA)

In this study, it is aimed to determine the antioxidant activity, total polyphenol and total flavonoid content of peanuts from four different market types, for the first time, and group them with principal component analysis (PCA) and hierarchical cluster analysis (HCA). The total polyphenol content changed 1.556 to 2.899 mg GAE/g.The lowest value have seen at Spanish merket type to determine the antioxidant activities of peanut samples were maked FRAP and DPPH assay, the lowest FRAP value (8.136 µmol FeSO47H2O/g sample) was seen at Valencia market type, the highest (14.004 µmol FeSO47H2O/g sample) was seen at Virginia market type. It was determined that the total flavonoid, total polyphenol, and antioxidant activities of the Virginia, Valencia, Spanish, and Runner market types included in the study were different from each other, and the Virginia market type showed superior characteristics compared to the others.PMID:38380875 | DOI:10.1002/cbdv.202301419
