Figure 2

Effect of ginseng extracts and individual ginsenosides on NO production in HUVECs. Confluent cells were incubated with 150 μg/mL ginseng extracts (CE, TE and DE), 26 μM Rg1, 31 μM Re, or 52 μM Rb1 for 10 min. Bio-imaging of intracellular NO (A) and NO release (B) were measured using DAF-2 DA and DAF-2, respectively. Each bar represents mean ± SD from three separate wells per condition. * P < 0.05 compared with control.
