Table 2 Antioxidant potential and total flavonoids in methanol and ethanol extracts of E. crassipes leaf powder through DPPH and FRAP assays

	DPPH assay (% scavenging activity)	FRAP assay (mM Fe²⁺/mg extract)	Total flavanoids (μg QEs/mg extract)
Methanol extract	48.15 ± 1.02^b	231.89 ± 2.95^b	30.46 ± 1.71^a
Ethanol extract	30.89 ± 1.21^a	192.24 ± 0.83^a	36.54 ± 0.76^b
Ascorbic acid	92.66 ± 1.02	1428.28 ± 146.20	--
Gallic acid	85.80 ± 3.76	2907.48 ± 299.71	--

Values are represented as mean ± SEM. Antioxidant potential of methanol and ethanol extracts were compared by calculating p values using t test, and p values less than 0.05 were considered significant. Dissimilar superscripts “a” and “b” in each assay represent that they are statistically different. Ascorbic acid and gallic acids were used as positive controls for DPPH and FRAP assays, respectively
