Abstract:

In this study, the American ginseng flower is pre-treated by high temperature and pressure and the ethanol extract of American ginseng flower is divided by n-hexane, chloroform, ethyl acetate and n-butanol consequently. A total of 10 different polar components are obtained. The best active fraction is screened by oxidative-induced H9c2 Cardromyocytes. The ability of free radical scavenging and chemical composition of the fractions are analyzed by LC-MS. The results show that the processed ethyl acetate extraction (PEE) of American ginseng flowers effectively protects oxidative-induced H9c2 Cardromyocytes, significantly improves cell viability and reduces cell ROS levels. Compared with the original ethyl acetate extraction (OEE), the ginsenoside content of the two groups is similar and shows strong antioxidant capacity. Through LC-MS analysis, it is preliminarily determined that Rk1 and Rg5 generated by high temperature and pressure transformation in PEE. Therefore, processed American ginseng flower has better protective effect on oxidative-induced H9c2 Cardromyocytes than original.
