In our continuing effort to investigate compounds having anti-inflammatory activity from natural products, Ailanthus altissima was examined. Among six compounds isolated from Ailanthus altissima, Luteolin-7-O-glucoside (L7G) along with ethanol extract of Ailnathus altissima (EAa) were chosen to determine their inhibitory activity on secretory recombinant phospholipase $A_2s$ enzyme activity in vitro. As a results, EAa inhibited human recombinant $sPLA_2-V$ ($IC_{50}$ of about 100 ${mu}g/ml$) and $cPLA_2$, ($IC_{50}$ of about 59 ${mu}g/ml$), while L7G showed strong inhibitory effect on $sPLA_2-A$, V and $cPLA_2$ with an $IC_{50}$ value of approximately 40 ${mu}M$, respectively.
