In Mexico, Cnidoscolus aconitifolius (chaya) has been used to treat cardiovascular diseases (CVD). Because CVD are the number one cause of mortality, chaya use has become a health strategy. The aim of this study was to evaluate the antithrombotic activity and identify the metabolites in the most active extract. Aqueous (Aq), ethanolic (EtOH), acetonic (An), ethyl acetate (AcOEt), diethyl ether (Et₂O), and hexanic (Hx) extracts were obtained. Platelet aggregation, phospholipase A₂, prothrombin time (PT), activated partial thromboplastin time (aPTT), and clot lysis were evaluated. Metabolites were identified by gas chromatography–mass spectrometry (GC-MS). EtOH showed the greatest inhibition of platelet aggregation and phospholipase A₂. Ac had the greatest effect on PT and aPTT. AcOEt had the greatest effect on clot lysis. EtOH, with the highest potential, was analyzed by GC-MS; fatty acids and triterpenes were identified. Thus, EtOH showed greater antiplatelet activity and other extracts showed moderate activity. This is a preliminary antithrombotic study. Future research will allow the development of nutraceuticals or functional ingredients for the prevention and treatment of thrombosis.
