Antioxidant Activity of Branches of Fuyu and Nishimurawase Persimmon Trees

Abstract

The antioxidant activities of two persimmon (Diospyros kaki T.) branches were evaluated. After preparing acetone, 70% acetone, and methanol extracts from Fuyu and Nishimurawase persimmon branches, DPPH radical scavenging activity (RSA), ABTS RSA, reducing power (RP), and total phenol contents (TPC) were determined. The acetone extracts of Fuyu and Nishimurawase showed higher antioxidant properties than the other extracts. The highest TPC (22.48 mg/g), DPPH RSA (IC 50 =701.48 µg/mL), ABTS RSA (IC 50 =493.76 µg/mL), and RP (IC 50 =1218.57 µg/mL) were found in acetone extract of Fuyu, while the lowest antioxidant activities were in 70% acetone extract of Nishimurawase. The results suggest that sweet persimmon branches exhibit considerable antioxidant activity.

Antioxidative Properties of Different Solvent Extracts from Persimmon (Diospyros kaki cv. Fuyu) Flower-Buds

“…There was no correlation between TPC and ABTS RSA. In the study of the antioxidant activity of fuyu persimmon tree branches, the IC 50 value of the acetone extract for ABTS RSA was determined as 493.76 μg/mL (23). The branch of persimmon had lower antioxidant activity, because the amount of polyphenol was lower than persimmon flower-bud (23).…”
