Table 1.
Comparison of total polyphenol, flavonoid and tannin contents of extracts from Amaranth seeds.

Sample	Total phenolic content (mg GAE1)/g)	Total flavonoid content (mg CE2)/g)	Tannin content (mg TAE3)/g)
Methanol ext.	1.69±0.12	1.53±0.17	0.316±0.048
Water ext.	4.23±1.00	0.08±0.00	0.511±0.012

Total phenolic content was expressed as mg/g gallic acid equivalent (GAE).
Total flavonoid content was expressed as mg/g catechin equivalent (CE).
Tannic acid content was expressed as mg/g tannic acid equivalent (TAE).
Each value is mean±SD of triplicate determinations (n=3).
