Three data fusion strategies (low-llevel, mid-llevel, and high-llevel) combined with a multivariate classification algorithm (random forest, RF) were applied to authenticate the geographical origins of Panax notoginseng collected from five regions of Yunnan province in China. In low-level fusion, the original data from two spectra (Fourier transform mid-IR spectrum and near-IR spectrum) were directly concatenated into a new matrix, which then was applied for the classification. Mid-level fusion was the strategy that inputted variables extracted from the spectral data into an RF classification model...

Panax notoginseng saponins (PNS) have been widely used in the cardiovascular system for the treatment of cardiovascular diseases and stroke in China. In this study, we investigated the anti-apoptotic effect of PNS on cardiomyocytes in the natural aging rat and explored the potential mechanisms regarding oxidative stress and mitochondrial function signaling pathways. Male Sprague-Dawley rats were randomly divided into five groups: adult control (3-month old), aging control (24-month old), and different doses of PNS-treated aging rat groups (10, 30, 60 mg/kg/day, orally)...

Although Panax notoginseng (PN) roots in raw and steamed forms were historically supposed to be different in the efficacies, the raw materials and steamed ones were often undifferentiated in the use and market circulation, which might bring unstable curative effects or even adverse reactions. To uncover chemical constituents responsible to different activities of raw and steamed PN, chemometrics analyses including partial least squares regression (PLSR) and multi-linear regression analysis (MLRA) were used to establish the relationships between the chromatographic fingerprints and activities of PN samples...

Coronary artery disease (CAD) is a major public health problem and the chief cause of morbidity and mortality worldwide. Panax notoginseng, a valuable herb in traditional Chinese medicine (TCM) with obvious efficacy and favorable safety, shows a great promise as a novel option for CAD and is increasingly recognized clinically. Firstly, this review introduced recent clinical trials on treatment with PNS either alone or in combination with conventional drugs as novel treatment strategies. Then we discussed the mechanisms of P...

Impaired angiogenesis is one of the crucial factors that impede the wound healing process in diabetic foot ulcers (DFUs). In this study, we found that 20(S)-protopanaxadiol (PPD), an aglycone of ginsenosides in Panax notoginseng, stimulated angiogenesis and benefited wound healing in genetically diabetic mice. In HUVECs, PPD promoted cell proliferation, tube formation and VEGF secretion accompanied by increased nuclear translocalization of HIF-1α, which led to elevated VEGF mRNA expression. PPD activated both PI3K/Akt/mTOR and Raf/MEK/ERK signaling pathways in HUVECs, which were abrogated by LY294002 and PD98059...

Methanol and water are commonly used solvents for chemical analysis and traditional decoction, respectively. In the present study, a high-performance liquid chromatography with ultraviolet detection method was developed to quantify 11 saponins in Panax notoginseng Flower extracted by aqueous and methanol solutions, and chemical components and anti-inflammatory effects of these two extracts were compared. The separation of 11 saponins, including notoginsenoside Fc and ginsenoside Rc, was well achieved on a Zorbax SB C18 column...

To achieve a molecular method to identify Panax ginseng, P. notoginseng,P. quinquefolius and their admixture. The ITS,18S and matK sequences of Panax genus were analyzed to develop species-specific SNP marker. Three pairs of species-specific primers were designed to establish a multiplex allele-specific polymerase chain reaction (MAS-PCR) and the samples from different region were tested. The results showed that when the annealing temperature was 60 ℃ and the cycle number was 35, approximately 250, 500,1 000 bp specific band were obtained from P...

Panax notoginseng medicinal liquor (PML) has a long history of use in the function of blood circulation. However, the processing of PML is currently dependent on experience, which results in low efficiency and unstable quality of PML. A variety of substances of P. notoginseng have a strong ability to scavenge free radicals and antioxidant activity, but the antioxidant activity of PML has not been formally researched. The aim of the present study was to optimize the processing technology of PML and to verify the anti-oxidation and anti-deposition of melanin functions of PML...

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 (NSCs) of embryonic rat brain was investigated. The present study used MTS assays to identify the optimum dose and window time of ginsenoside‑Rg1 administration to stimulate the proliferation of cortical NSCs in the rat embryonic tissue...

Natural products are of great surge in the identification of chemopreventive agents and biologically active molecules for the development of new promising therapeutic agents. These agents influence the cascade of biochemical and molecular signalling pathways involved in numerous physiological and pathological processes. The natural agents combat the dogma associated with the most dreaded, unconquered health concern and a multigenic disease- cancer. A category of plants known as adaptogens maintain perturbed homoeostasis, augment adaptations to noxious stimuli (exposure to cold, heat, pain, general stress, infectious organisms) and offer endurance to attenuate several disorders in human beings...

Ginsenoside Rk3 (Rk3) is present in the roots of processed Panax notoginseng herbs and it exerts anti-platelet aggregation, pro-immunogenic and cardioprotective effects. However, little is known regarding the anticancer activities of this compound, especially in lung cancer. This study was designed to investigate the anticancer effects of Rk3 on non-small cell lung cancer (NSCLC) cells and in an H460 xenograft tumor model. Our results showed that Rk3 reduced cell viability, inhibited both cell proliferation and colony formation, and induced G1 phase cell cycle arrest by downregulating the expression of cyclin D1 and CDK4 and upregulating the expression of P21...
