SBHE = Salix babylonica hydroalcoholic extract. ASB = Aqueous fraction. ACSB = Organic fraction. F1AC to F10AC = subfractions obtained from ACSB. NA = No activity. ND = No determined due to solubility problems. Different literals in the column show significant differences (p ≤ 0.05) among the compounds evaluated.
