Abstract

The water extracts of 82 Korean medicinal herbs were prepared and were examined for the binding affinity on the glycine binding site of NMDA (N-methyl-D-aspartate) receptor prepared by the synaptic membranes from the forebrains of male Sprague-Dawley rats. Among the tested, the extracts of Dioscoreae Rhizoma, Hoveniae Semen cum Fructus, Astragali Radix, Armeniacae Semen, Huttuynia cordata Herba, Acanthopanacis Cortex, Aurantii nobilis Pericarpium, Phellinus linteus, Amomi Fructus, Artemisiae capillaris Herba, Polyporus, Agastachis Herba and of Galli Stomachichum Corium were found to exhibit significant competitions with $[^3H]-MDL$ 105,519 for the glycine specific binding site of NMDA receptor in a dose dependent manner, respectively.
