The purpose of this study was to investigate the antibacterial activity of extracts from Zostera marina against the pathogens of Apostichopus japonicus skin ulceration disease.When 95% ethanol (v/v) solvent was used to extract Zostera marina at 50℃,aqueous extract (ZA) showed obvious bacteriostatic effects on the tested bacterial strains (inhibition halo diameters between 8.23 mm and 13.62 mm),whereas the ethyl acetate extract (ZE) was almost inactive.The minimal inhibitory concentration (MIC) of ZA against four pathogens were homogeneous at 12.8 g L-1.ZA components were analyzed by thin layer chromatography (TLC) assay and six fractions were obtained.In another study,the six fractions showed inhibitory effects against the tested bacteria while their functions seemed to counteract the ZA activity.

Whhen 95% ethanol (v / v) solvent was used to extract Zostera marina at 50 ° C, aqueous extract (ZA ) showed obvious bacteriostatic effects on the tested bacterial strain (inhibition halo halo between between 8.23 mm and 13.62 mm), while the ethyl acetate extract (ZE) was almost inactive. These minimal inhibitory concentrations (MIC) of ZA against four pathogens were homogeneous at 12.8 g L-1. ZA components were analyzed by thin layer chromatography (TLC) assay and six fractions were obtained. Another study, the six shares showed inhibitory effects against the tested bacteria while their functions seemed to counteract the ZA activity.
