Rhizoma Polygoni Cuspidati, a Chinese herbal drug, has actions of dispelling dampness, alleviating jaundice, clearing heat, subsiding toxin, activating blood, and removing stasis. Polydatin (PD), one of its chief active ingredients, has been proved by modern pharmacological studies to possess extensive cardiovascular pharmacological activity, showing marked effects on protecting cardio-myocyte, dilating blood vessel, antagonizing platelet aggregation, thrombosis, and atherosclerosis. The progress of the research on cardiovascular pharmacological actions and the acting mechanism of PD was reviewed in this paper.

Rhizoma Polygoni Cuspidati, a Chinese herbal medicine, has been widely used in traditional Chinese medicine for a long time. Polydatin, one of the major active ingredients in Rhizoma Polygoni Cuspidati, has been recently shown to possess extensive cardiovascular pharmacological activities. In present study, we examined the effects of Polydatin on the formation of peritoneal macrophage-derived foam cells in Apolipoprotein E gene knockout mice (ApoE−/−) and explored the potential underlying mechanisms. Peritoneal macrophages were collected from ApoE−/− mice and cultured in vitro. These cells sequentially were divided into four groups: Control group, Model group, Lovastatin group, and Polydatin group. Our results demonstrated that Polydatin significantly inhibits the formation of foam cells derived from peritoneal macrophages. Further studies indicated that Polydatin regulates the metabolism of intracellular lipid and possesses anti-inflammatory effects, which may be regulated through the PPAR-γ signaling pathways.

RYR has the anti-atherosclerotic and stabilizing unstable plaque effects. The mechanism might be related to the inflflammatory signaling pathways.
