Invitro Antioxidant Activity Of Ginger

Author(s) Eshanika S

Abstract Ginger, or Zingiber officinale Rosc., is a medicinal spice commonly employed for antioxidant activities. The present study was designed to assess the antioxidant activity of ginger extract using different antioxidant assays. Fresh ginger was collected, cleaned, dried, and powdered, and the extract was prepared using methanol as a solvent. The extract was concentrated using a Soxhlet apparatus or maceration. The extract was tested for antioxidant activity using different assays. Phytochemical screening of ginger extract showed the presence of polyphenols, flavonoids, and terpenoids. The antioxidant activity of ginger extract was evaluated using DPPH, ABTS, FRAP, hydrogen peroxide, and phenolic content assays. The results of this study showed that ginger extract possessed antioxidant activity, as indicated by DPPH and ABTS radical scavenging activity, and the IC50 value of ginger extract was within the range of [50-100] µg/mL. The antioxidant activity of ginger extract was comparable to that of ascorbic acid or gallic acid. The antioxidant activity of ginger extract was also evident from the FRAP assay, in which ginger extract showed significant antioxidant activity. The hydrogen peroxide scavenging activity of ginger extract increased with increasing concentration. The phenolic content of ginger extract was within the range of [80-120] mg/g.. The antioxidant activities observed are consistent with the phenolic constituents of ginger, which confirms the traditional use of ginger as a health-promoting food and indicates its possible use as a natural antioxidant for the production of functional foods and nutraceuticals.
