| Summary: | We investigated the aqueous and ethanolic extracts of different forms (local names: mura and chora) of turmeric (Curcuma longa)
from the Khulna and Chittagong divisions of Bangladesh for their antioxidant properties and polyphenol, flavonoid, tannin, and
ascorbic acid contents. The antioxidant activity was determined using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radicalscavenging
activity and ferric reducing antioxidant power (FRAP) values. The ethanolic extract of Chittagong’s mura contained
the highest concentrations of polyphenols (16.07%), flavonoids (9.66%), and ascorbic acid (0.09mg/100 g) and chora resulted in
high yields (17.39%). The ethanolic extract of Khulna’s mura showed a higher DPPH radical-scavenging activity with the lowest
50% inhibitory concentration (IC50) (1.08
