Abstract

Highlights

• Sugar-free extracts of tamarillo, horned melon (kiwano), and raspberry inhibited ADP-induced platelet aggregation in platelet-rich plasma.

• Analysis of untargeted metabolites revealed the presence of platelet inhibitory components such as benzoic acid, caffeic acid, and gallic acid in the sugar-free extracts of tamarillo, raspberry, and kiwano but not in pear extract.

• Extract of pear had no platelet anti-aggregatory effect.

• Tamarillo, horned melon (kiwano), and raspberry reduced the synthesis of TxB2 and the release of platelet factor 4.

Abstract

In addition to their roles in thrombosis, hyperactive platelets contribute to atherosclerosis. Since anti-platelet drugs are not recommended for the vulnerable population with hyperactive platelets to reduce the risk of cardiovascular disease, a search is on to find alternative dietary antiplatelets that can be safely used. We here describe that in a dose-dependent manner, sugar-free extracts of tamarillo, horned melon (kiwano), and raspberry inhibited ADP-induced platelet aggregation in platelet-rich plasma, whereas pear extract had no effects. Furthermore, analysis of untargeted metabolites revealed the presence of platelet inhibitory components such as benzoic acid, caffeic acid, and gallic acid in the sugar-free extracts of tamarillo, raspberry, and kiwano but absent in pear extract. All these three fruit extracts inhibited the platelet production of TxB2 and the release of platelet factor 4. Our work suggests that these fruits inhibit platelet aggregation partly due to anti-platelet compounds such as benzoic, caffeic, and gallic acids.
