LC-MS Analysis of Ginsenosides in Different Parts of Panax quinquefolius and Their Potential for Coronary Disease Improvement.

Seven main ginsenosides, including ginsenoside Re, ginsenoside Rb, pseudoginsenoside F, ginsenoside Rb, ginsenoside Rb, ginsenoside Rd, and ginsenoside F, were identified by LC-QTOF MS/MS from root, leaf and flower extracts of . These extracts promoted intersegmental vessel growth in a zebrafish model, indicating their potential cardiovascular health benefits. Network pharmacology analysis was then conducted to reveal the potential mechanisms of ginsenoside activity in the treatment of coronary artery disease. GO and KEGG enrichment analyses elucidated that G protein-coupled receptors played a critical role in VEGF-mediated signal transduction and that the molecular pathways associated with ginsenoside activity are involved in neuroactive ligand-receptor interaction, cholesterol metabolism, the cGMP-PKG signaling pathway, etc. Moreover, VEGF, FGF2, and STAT3 were confirmed as the major targets inducing proliferation of endothelial cells and driving the pro-angiogenic process. Overall, ginsenosides could be potent nutraceutical agents that act to reduce the risks of cardiovascular disease. Our findings will provide a basis to utilize the whole plant in drugs and functional foods.
