The treatment of malignant tumors following surgery is important in preventing relapse. Among all the post-surgery treatments, immunomodulators have demonstrated satisfactory effects on preventing recurrence according to recent studies. Ginsenoside is a compound isolated from panax ginseng, which is a famous traditional Chinese medicine. Ginsenoside aids in killing tumor cells through numerous ...

BACKGROUND Ginsenoside Rg3 is a promising anticancer agent. It is usually produced by heat treatment of ginseng, in which ginsenoside Rb1 is the major ginsenoside. A kinetic study was conducted to optimize ginsenoside Rg3 production by the heat treatment of ginsenoside Rb1. METHODS Ginsenoside Rb1 was heated using an isothermal machine at 80°C and 100°C and analyzed using HPLC. The kinetic pa...

Cultured Schwann cells were treated with 5.6 mM and 50 mM glucose alternating every 8 hours to simulate intermittent high glucose. The present study analyzed the neuroprotective effects of 1, 10 and 100 μM ginsenoside Rb1 on oxidative damage and apoptosis in Schwann cells induced by intermittent high glucose. Flow cytometry demonstrated that ginsenoside Rb1 reduced intermittent high glucose-med...

Ginsenoside Rb2 is one of the major active components of Panax ginseng. There is little research about cardioprotective effect of ginsenoside Rb2. The aim of this study was to explore the cardioprotective effects of ginsenoside Rb2 on animal model of myocardial ischemia/reperfusion (MI/R) injury in vivo and H2O2-induced stress in H9c2 cells in vitro. Pretreatment with ginsenoside Rb2 (10 and 20...

Ginsenoside‑Rg1, the main active component of Panax notoginseng, exhibits a number of pharmacological functions, including promoting protein synthesis in the brain, increasing the number of synapses, improving memory and promoting recovery of brain function following injury. The effect of ginsenoside‑Rg1 on proliferation and glial‑like‑directed differentiation in the cortical neural stem cells ...

A high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) method was successfully developed and validated for the identification and determination of eight ginsenosides: ginsenoside Rg₁ (1); 20(S)-ginsenoside Rh₁ (2); 20(S)-ginsenoside Rg₂ (3); 20(R)-ginsenoside Rh₁ (4); 20(R)-ginsenoside Rg₂ (5); ginsenoside Rd (6); 20(S)-ginsenoside Rg₃ (7); and ...

The present study was carried out to evaluate the inhibitory effects of ginsenoside Rh2 on nuclear-factor- (NF-) κ B in lipopolysaccharide- (LPS-) activated RAW 264.7 murine macrophages. RAW 264.7 cells were pretreated with indicated concentrations of ginsenoside Rh2 for 1 h prior to the incubation of LPS (1  μ g/mL) for indicated time period. Ginsenoside Rh2 reduced CD14 and Toll-like receptor...

BACKGROUND Root of Panax ginseng C. A. Mey (Renseng in Chinese) is a famous Traditional Chinese Medicine. Ginsenosides are the major bioactive components. However, the shortage and high cost of some ginsenoside reference standards make it is difficult for quality control of P. ginseng. OBJECTIVE A method, single standard for determination of multicomponents (SSDMC), was developed for the simu...

To determine the hapten number in hapten-carrier protein conjugate matrix-assisted laser desorption/ionization (MALDI) tof mass spectrometry was applied. Highly specific anti-ginsenoside Rb1 and Rg1 monoclonal antibodies (MAbs) were prepared. Ginsenosides were developed on thin layer chromatography (TLC) plates which were covered by a polyvinylidene difluoride (PVDF) membrane resulting in blott...

BACKGROUND Minor saponins or human intestinal bacterial metabolites, such as ginsenosides Rg3, F2, Rh2, and compound K, are more pharmacologically active than major saponins, such as ginsenosides Rb1, Rb2, and Rc. In this work, enzymatic hydrolysis of ginsenoside Rb1 was studied using enzyme preparations from cultured mycelia of mushrooms. METHODS Mycelia of Armillaria mellea, Ganoderma lucid...
