Polydatin research

is widely distributed in plants, and the content is relatively high. At present, Polydatin have been found in at least 70 plants and are the main functional components of Polygoni Cuspidati. Research show that it has significant effects on cardiomyocytes, vascular smooth muscle cells, and improving microcirculation. In addition, Polydatin can reduce tissue and organ damage caused by many factors, protect the liver, inhibit platelet aggregation, relieve cough and asthma, resistance to germs & virus, Lowering blood lipids and anti-lipid peroxidation effects [1-7] . Polydatins are functional components that exist in natural plants and have a variety of pharmacological effects. Due to the low cost of raw materials and abundant resources, they are ideal raw materials for the production of health foods. At present, more than ten countries and regions in the world are developing raw materials and preparations of Polydatins. According to relevant statistics, the global market for Polydatins has an annual demand of more than 100 tons. In the next few years, the demand will remain to increase, and the current annual production capacity of polydatins is about 50-60t. It can be seen that the demand gap is large and the market prospect is extremely broad [8]. However, the current research on polydatins in China is mainly focused on pharmacological research. The lack of theoretical and technical research on the stability of polydatins of is likely to cause unnecessary losses during the extraction and purification process. Unable to effectively preserve Polydatins. Therefore, the reference substance for polydatins was selected as the research object, and its stability was studied under different conditions, which laid a theoretical foundation for the extraction, purification, development and utilization of polydatins.
