Table 4

FRAP and IC₅₀ of DPPH values of turmeric varieties (mura and chora) collected from the Khulna and Chittagong divisions.

Parameters	KMW	KME	KCW	KCE	CMW	CME	CCW	CCE
DPPH radical-scavenging activity, IC50 (µg/mL)	5.31	1.08	12.51	3.03	13.42	1.97	16.55	1.19
FRAP (µM Fe per 100 g of sample)	646.67 ± 2.48	3475.36 ± 173.10	1015.52 ± 3.11	4204.46 ± 74.48	681.18 ± 24.20	3231.89 ± 337.10	976.61 ± 2.48	1972.66 ± 104.78

FRAP data are expressed as the mean ± SD. IC₅₀: inhibitory concentration 50%. Different letters (a, b, c, and d) in each row indicate a significant difference ().
