TOTAL ANTI-OXIDANT CAPACITY, FLAVONOID, PHENOLIC ACID AND POLYPHENOL CONTENT IN TEN SELECTED SPECIES OF ZINGIBERACEAE RHIZOMES
Background: Natural products such as herbs, fruits, spices, beverages, vegetables are becoming more popular among scientific community and consumers because of their potential to arrest the effect of free radicals in human system. This study determined the total antioxidant capacity of ten selected...

| description | Background: Natural products such as herbs, fruits, spices, beverages,
vegetables are becoming more popular among scientific community and
consumers because of their potential to arrest the effect of free
radicals in human system. This study determined the total antioxidant
capacity of ten selected species of Zingiberaceae (Ginger) used as
spices and for medicinal purposes in Southeast Asia. Materials and
Methods: Methanol was used as the extraction solvent, 2,2 -
diphenyl -1- picrylhydrazil (DPPH) for free radical scavenging activity
and ferric reducing antioxidant power (FRAP) assays. Phenolic compounds
were measured using Total flavonoid, Phenolic acid and Polyphenols
content assay to evaluate the quality of the antioxidant capacity of
the rhizomes and vitamin C as positive control. Results: The results
obtained revealed that Curcuma longa and Zingiber officinale had
the highest free radical scavenging capacity of 270.07mg/TE/g DW and
266.95mg/TE/g DW and FRAP assay, Curcuma longa and Zingiber officinale
also gave the highest ferric reducing power of 231.73mg/TE/g DW and
176.26mg/TE/g DW respectively. For Phenolic compounds, Curcuma longa
and Curcuma xanthorrhiza gave the highest values of flavonoid
(741.36mg/NGN/g DW and 220.53mg/NGN/g DW), phenolic acid (42.71mg/GAE/g
DW and 22.03mg/GAE/g DW) and polyphenols (39.38mg/GAE/g DW and
38.01mg/GAE/g DW) respectively. Significant and positive linear
correlations were found between Total antioxidant capacity and Phenolic
compounds (R = 0.65 - 0.96). Conclusion: This study provides
evidence that extracts of Zingiberaceae (Ginger) rhizomes are a
potential source of natural antioxidants and could serve as basis for
future drugs and food supplements |
