Clovamide and clovamide-rich extracts of three Trifolium species as antioxidants and moderate antiplatelet agents in vitro

This is the first study on clovamide-rich preparations from Trifolium clypeatum, T. obscurum and T. squarrosum. The extracts displayed considerable antioxidant properties, slightly reduced the haemostatic activity of blood platelets and were non-cytotoxic in vitro.251
