| description | Ginger rhizome (Zingiber officinale Roscoe) has many diverse properties and medicinal values such as antioxidant potential combined with the properties of a spice. Dried ginger (DG) were extracted with aqueous ethanol and freeze-dried. The extract was evaluated for antioxidant potential, using 1,1'-diphenyl-2-picryl-hydrazyl radical scavenging, antioxidant capacity and reducing power assays. DG extract was further fractionated into methanol (Mfr) and water-soluble (Wfr) fractions. The Mfr exhibited higher antioxidant capacity when compared to DG extract. Higher antioxidant potential of the methanol fraction may be due to the presence higher polyphenols and [6]-gingerol content. This suggests that alcoholic soluble fraction possess enormous scope to enhance the antioxidant potential when used as a supplement in various food as well as pharmaceutical formulations / products. |
