Correlation of phytochemical content with antioxidant potential of various sweet potato (Ipomoea batatas) in West Java, Indonesia

Objective: To determine antioxidant activity and phytochemical content from various tubers extracts of sweet potato (Ipomoea batatas) and to explore the correlation of phytochemical content with their antioxidant activities. Methods: Antioxidant activities were tested using DPPH and FRAP assays. Total phenolic was calculated by Folin-Ciocalteu reagent, flavonoid content by Chang's method and correlation with their antioxidant activities were analyzed by Pearson's method. Results: PO2 showed highest antioxidant activity, which had the lowest IC
