As a continuation of the previous study, a second group of sixty two aqueous extracts(freeze dried) from natural products was screened for the inhibitory effect of platelet activating factor(PAF) binding to rabbit platelet using 0.6 nM [$^{3}$H]PAF as a radioligand. The results demonstrated that three medicinal plants inhibited 40~50% of [$^{3}$H]PAF equilibrium binding at the concentration of 200 $\mu\textrm{g}$/ml.
