Abstract
The present study was performed to evaluate the effect of steaming ginseng at a temperature over 100 °C on its chemical constituents and biological activities. Raw ginseng was steamed at 100, 110, and 120 °C for 2 h using an autoclave. The ginseng steamed at 120 °C was more potent in its ability to induce endothelium-dependent relaxation. Steaming the raw ginseng at 120 °C also remarkably increased the radical-scavenging activity. Ginsenosides F4, Rg3, and Rg5, which were not present in raw ginseng, were produced after steaming. Ginsenosides Rg3 and Rg5 were the most abundant ginsenosides in the ginseng steamed at 120 °C, accounting for 39% and 19% of all ginsenosides, respectively.Keywords
