Antioxidant activity of ethanol extract of poncirus fructus immaturus

초록

The present study investigated the antioxidant activity of ethanol extracts derived from Ponciri fructus immaturus using various in vitro antioxidant assays. Poncirus fructus immaturus samples were pulverized and extracted using 70% of ethanol and it was concentrated using a rotary evaporator. The concentrated samples were dissolved in respective solvent for antioxidant tests including DPPH radical scavenging, superoxide radical scavenging, metal-chelating reducing power and total antioxidant assays. Analytical results revealed that ethanol extract of Poncirus fructus immaturus contains the phenolic content of 60.81 mg TAE.g -1 and flavonoid content of 17.50 mg QE.g -1 . Further, same extracts exhibited the concentration dependent antioxidant activity. Among the different level of concentrations tested, 800 μg.ml -1 of Poncirus fructus immaturus extract bared the higher 2,2-diphenyl-1-picrylhydrazyl (DPPH), superoxide radical scavenging, metal-chelating, reducing power and total antioxidant activities. Present findings revealed the importance of Poncirus fructus immaturus as a potent source for antioxidant ingredient. © 2019, World Research Association. All rights reserved.
