Values with the different superscript alphabets in the same row differ significantly at P < 0.05. Means preceded by different superscript letters differ significantly (P < 0.05) from one another: a and b (between DW and ALB, Extract and fractions), c and d (between ALB and the fractions), e and f (between the extract)
DW, distilled water; ALB, albendazole; CME, crude methanol extracts; HF, hexane fraction; BF, butanol fraction; EAF, ethyl acetate fraction
