Abstract

Seaweeds are a famous traditional food resource in some countries containing different types of secondary metabolites. These marine organisms have shown different biological activities. The aim of this study was to investigate the effects of hexane and methanol extracts of Sargassum plagyophylum on depression. Sargassum plagyophylum was collected from Persian Gulf. The plant was extracted by maceration with methanol-ethyl acetate solvent. The extract was evaporated and partitioned by hexane and methanol solvents. The two partitions were administered i.p. to male mice either a single dose or for 7a†days. Depression was evaluated by the forced swimming test (FST) which higher immobility time indicates depressive-like behavior. The immobility time during FST decreased significantly by all the doses of the hexane partitions (notably 40 mg/kg; 10a†s ± 2 vs. 114a†s ± 12 control group). However, only the lowest dose (20 mg/kg) of the methanol partition reduced immobility time during FST (23a†s ± 8, p<0.001). Following the long term administration both of the partitions reduced the immobility time in FST (hexane 27a†s ± 11, methanol 70a†s ± 14, p<0.05 vs. control 140a†s ± 14). The hexane partition showed antidepressant effects not only by long-term administration but also by the single dose during FST. The 7a†days therapy with methanol partition also induced antidepressant behavior, but only the lowest single dose reduced immobility in FST. The methanol partitions possibly have certain substance that interfered with behavior in the FST. Therefore, S. plagyophylum should be considered for further antidepressant studies. © 2019 2019 Walter de Gruyter GmbH, Berlin/Boston.
