Table 1. Total phenolic content and evaluation of the free radical scavenging activity of EE96 and eluates EL30–EL70.

Eluate	Total phenolic content (g GAE/L)	Free radical scavenging activity (g GAE/L)
EE96	1.99±0.01^a	1.88±0.01^a
EL30	0.26±0.01^d	0.18±0.08^d
EL40	0.39±0.01^c	0.33±0.08^c
EL50	0.26±0.01^d	0.30±0.05^c
EL60	0.82±0.01^b	1.20±0.03^b
EL70	0.83±0.02^b	1.22±0.02^b

Data are means ±S.D. (n = 3); values in the same column followed by the same letter (a-d) are not statistically different (P<0.05), as measured by Duncan’s test.

EE96, ethanolic extract of crude propolis extract prepared using SPE with 96% ethanol elution.

EL30-EL70, eluates of the crude propolis extract prepared using SPE with 30% to 70% ethanol elution.

GAE, gallic acid equivalent.
