The $CHCl_3$, EtOAc, and n-BuOH fractions showed a marked inhibition of 5% fatal bovine serum (FBS)-induced cell proliferation. The $IC_{50}$ values of the chloroform fractions from leaf, stem, and root as well as the n-BuOH and EtOAc fraction from root on cell proliferation were $1.2{\pm}0.4$, $17.2{\pm}6.4$, $81.8{\pm}33.2$, $40.8{\pm}8.0$, and $237.1{\pm}85.6\;{\mu}g/mL$, respectively. On the other hand, the EtOAc fractions, and the $CHCl_3$ fraction significantly inhibited collagen-, arachidonic acid-, U46619-, and thrombin-induced platelet aggregations. The $IC_{50}$ values of EtOAc fraction from leaf, and the $CHCl_3$ and EtOAc fraction from stem were $214.1{\pm}12.2$, $134.3{\pm}2.5$, and $42.6{\pm}7.0\;{\mu}g/mL$ with collagen, $312.4{\pm}7.5$, $158.9{\pm}1.7$, and $82.2{\pm}2.7\;{\mu}g/mL$ with arachidonic acid, $31.1{\pm}2.4$, $48.7{\pm}0.3$, and $29.7{\pm}1.1\;{\mu}g/mL$ with U46619, and $36.7{\pm}2.4$, $69.1{\pm}11.3$, and $34.2{\pm}0.1\;{\mu}g/mL$ with thrombin, respectively. Taken together, these data provide new evidence that fractions from Allium victorialis var. platyphyllum (AVP) are able to inhibit vascular smooth muscle cell (VSMC) proliferation and platelet aggregation, which may be a novel resource for the development of anti-atherothrombotic agents.
