L. and &lt;em&gt;Cosmos caudatus&lt;/em&gt; Kunth. are rich in flavonoids, saponins and essential oils. This study was carried out to determine the antiplatelet effect of the three plant extracts on ADP-induced platelet aggregation. &lt;strong&gt;Methods:&lt;/strong&gt; The samples consisted of clopidogrel as positive control, aquadest as negative control and test extracts with concentrations of 40, 60, 80 and 100 mg/ml. Platelet Rich Plasma (PRP) was added for each extract concentration. The absorbance test of the samples was measured at 600 nm, before and after the addition of 20 &amp;mu;L adenosine diphosphate (ADP) 5 mM. After ADP added, then measured again the plasma absorbance was measured of the same wavelength. Antiplatelet aggregation activity was determined by calculating plasma absorbance before and after addition of ADP. &lt;strong&gt;Results:&lt;/strong&gt; The results showed that the inhibitory percentage of platelet aggregation with extract concentrations of 100, 80, 60 and 40 mg/ml were &lt;em&gt;Lantana camara&lt;/em&gt; L. leaf extract (91.17%; 73.27%; 72.86% and 37.15%), &lt;em&gt;Eclipta prostrata&lt;/em&gt; (L.) L. leaf extract (74.55%; 65.60%; 48.00% dan 39.08%) and &lt;em&gt;Cosmos caudatus&lt;/em&gt; Kunth. Leaf extract (59.17%; 52.56%; 14.25% dan 13.82%), respectively. The test extracts inhibited in vitro ADP-induced platelet aggregation with IC&lt;sub&gt;50&lt;/sub&gt; value were as follows: 47.09 mg/ml (&lt;em&gt;Lantana camara&lt;/em&gt; L), 59.02 mg/ml (&lt;em&gt;Eclipta prostrata&lt;/em&gt; (L.) L.) and 87.26 mg/ml (&lt;em&gt;Cosmos caudatus&lt;/em&gt; Kunth.) &lt;strong&gt;Conclusion:&lt;/strong&gt; The present work demonstrated that the three extracts could inhibit in-vitro ADP-induced platelet aggregation and the best potency was shown by &lt;em&gt;Lantana camara&lt;/em&gt; L leaf extract. </style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">581</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Ni Made Dwi Sandhiutami&lt;sup&gt;*&lt;/sup&gt;, Yesi Desmiaty, Noviyanti &lt;/strong&gt;&lt;/p&gt;
