Total phenolic contents of R. emodi fractions using the different solvents.

Fraction	Total Phenolic Content (mg GAE/g 1)
n-hexane	27.76 ± 0.49 a
n-butanol	133.49 ± 0.58 c
Ethyl acetate	209.21 ± 5.81 d
Dichloromethane	66.27 ± 0.34 b
Water	139.00 ± 2.12 c

¹ Total phenolic content is expressed as milligrams of gallic acid equivalents (GAE) per gram of dry weight for the sample. ^a–d Values within a column followed by different letters are significantly different (Duncan test, n = 3, p < 0.05).
