Platelets are the key players in the development of cardiovascular diseases as the microparticles generated by apoptotic platelets and platelet aggregation contribute actively towards the disease propagation. Thus, the aim of this study was to demonstrate the effect of a phytochemical which can prevent these two processes and thereby project it as a cardio-protective compound. Crocin, a natural carotenoid exhibits a wide spectrum of therapeutic potentials through its antioxidant property. The study demonstrated its effects on cytoplasmic apoptotic events of mitochondrial pathway in platelets. Collagen/calcium ionophore-A23187 stimulated platelets were treated with crocin and endogenous generation of reactive oxygen species (ROS) and hydrogen peroxide (H₂O₂) were measured. H₂O₂-induced changes in crocin-pretreated platelets such as intracellular calcium, mitochondrial …
