Screening of acetylcholinesterase inhibitors in marine organisms from the Caribbean Sea
The acetylcholinesterase inhibitory activity of 89 organic extracts
from marine organisms was evaluated through a TLC bioautography
methodology. Extracts from soft corals (Eunicea and Plexaura) were
the most active ...
Characterization of a humic acid extracted from marine sediment and its influence on the growth of marine diatoms
(Cambridge University Press, 2014-04)
Due to the input of humic substances from freshwater run-off into the marine habitat, the influences of such substances on marine organisms should not be neglected. We here investigate the effect of a humic acid (HA) extract ...
Comparative study on extracts from the tissue covering the stingers of freshwater (Potamotrygon falkneri) and marine (Dasyatis guttata) stingrays
