Platelet aggregation and anti-inflammatory effects of garden pea, Desi chickpea and Kabuli chickpea.

Inflammation is the natural body defense mechanism for the removal of injurious agents, necrosed cells and tissues from the body. This study was aimed to evaluate the anti-inflammatory and platelet aggregation effects of three medicinal plants of Pakistan. Methanolic extract of garden pea inhibited arachidonic acid (AA)-induced platelet aggregation (IC50 = 35 microg/mL) and platelet activating factor (PAF)-induced platelet aggregation (IC50 = 38 microg/mL) in a dose dependent fashion. Methanolic extract of Desi chickpea inhibited arachidonic acid (AA) induced platelet aggregation (IC50 value = AA = 46 microg/mL) in dose dependent fashion while was found not active against PAF-induced platelet aggregation. Methanolic extract of Kabuli chickpea was found not active against both arachidonic acid (AA)-induced platelet aggregation and PAF-induced platelet aggregation. The best potential to inhibit in vitro COX-2 activity showed garden pea (Pisum sativum: the synthesis of PGE2 reduced by 92% in comparison with untreated control wells) followed by Desi chickpea (Cicer arietinum var; 87% inhibition) and Kabuli chickpea extracts (Cicer arietinum var: 65% inhibition). All extracts were tested at concentration 20 microg/mL. in COX-2 assay. The results indicate that if the same were happening in vito, Garden pea, Desi chickpea and Kabuli chickpea could be useful as natural antithrombotic anti-inflammatory materials.
