Panax notoginseng

Reference standards.

Notoginsenoside Fc has perfect anti-platelet aggregatory effect.

Notoginsenoside R1(NR1) is the main ingredient with cardiovascular activity in Panax notoginseng, which has some neuronal protective, antihypertensive,antioxidant, anti-inflammatory, antiapoptotic, and immune-stimulatory activities. NR1 can counteract endotoxin-induced activation of endothelial cells in vitro and endotoxin-induced lethality in mice in vivo. NR1 inhibits TNF-α-induced PAI-1 overexpression via extracellular signal-related kinases (ERK1/2) and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (PKB) signaling pathways, it attenuates amyloid-β-induced damage in neurons by inhibiting reactive oxygen species and modulating MAPK activation.

Notoginsenoside Ft1 is a novel stimulator of angiogenesis, it stimulates angiogenesis via HIF-1α-mediated VEGF expression, with PI3K/AKT and Raf/MEK/ERK signaling cascades concurrently participating in the process; it has the potential therapeutic effect on human neuroblastoma, it can arrest the proliferation and elicited the apoptosis of SH-SY5Y cells possibly via p38 MAPK and ERK1/2 pathways.Notoginsenoside Ft1 activates both glucocorticoid and estrogen receptors to induce endothelium-dependent, nitric oxide-mediated relaxations in rat mesenteric arteries. Notoginsenoside Ft1 also provides a great potential application of it in clinics for patients with diabetic foot ulcers, it may accelerate diabetic wound healing by orchestrating multiple processes, including promoting fibroblast proliferation, enhancing angiogenesis, and attenuating inflammatory response.

Zingibroside R1 has anti-HIV-1 activity.

Notoginsenoside Fe can induce gap junction-mediated intercellular communication (GJIC) reductions; and gap junctions have been shown or are believed to be involved in the pathogenesis of many inherited and acquired human diseases, agents that regulate the GJIC function may facilitate prevention and treatment of GJIC-involved diseases.
