Evaluation of Phenolics Content, Flavonoids and Antioxidant activity of Curcuma amada (Mango Ginger) and Zingiber officinale (Ginger).
The Zingiberaceae, the largest family in Zingeberales, comprises generally 300 genera and 1000 species,and in pantropical, concentrated mainly in the old world, chiefly in Indonasia. Members of the family yield spices,dyes, perfumes, medicines, and number of ornamental species are cultivated for their showy flowers.Recently this plant has acquired great importance in the present day world with its antiaging, anticancer, antioxidant, anti-alzheimer’s diseases, and varity of other medicinal properties due to its significant potential. The present study aims at comparing the Phenolics content, Flavonoids and Antioxidant activity of Curcuma amada and Zingiber officinale. The antioxidant activity and phenolic contents of the leaves as determined by the 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay and the total amounts of phenolics and flavonoids were higher than those of the rhizomes. Zingiber officinale had higher antioxidant activities as well as total contents of phenolic and flavonoid in comparison with Curcuma amada. This study validated the medicinal potential of the leaves and rhizome of Zingiber officinale and the positive relationship between total phenolics content and antioxidant activities in Zingiber officinale.
