Abstract (sommario):

American ginseng and Asian ginseng, which occupy prominent positions in the list of best-selling natural products in the West and East, are suitable for different indications in the traditional pharmacological uses. Currently, the effects of American ginseng and Asian ginseng in the protection against metabolic dysfunction and the differences between them are still unknown. Herein, an untargeted metabolomics based on liquid chromatography-quadrupole time-of-flight mass spectrometry (LC-Q-TOF-MS) was determined. The serum metabolomics and dynamic feces metabolomics revealed significant metaboli

Abstract (sommario):

American ginseng (Panax quinquefolius L.) has been recognized as a valuable herb medicine, and ginsenosides are the most important components responsible for the health-beneficial effects. This study investigated the secondary metabolites responsible for the differentiation of wild and cultivated American ginsengs with ultrahigh-performance liquid chromatography-high resolution mass spectrometry (UHPLC-HRMS)-based metabolomic approach. An in-house ginsenoside library was developed to facilitate data processing and metabolite identification. Data visualization methods, such as heatmaps and volc

The term ginseng refers to the dried roots of several plants belonging to the genus Panax of the Araliaceae family. The 3 major commercial ginsengs are Panax notoginseng (Burk.) F.H. Chen (Notoginseng), P. ginseng C.A. Meyer (Ginseng), and P. quinquefolius L. (American ginseng), which have been used as herbal medicines. Over 18,000 papers on ginsengs have been published on the basis of their structural diversity and biological activities.

Abstract (sommario):

It has been reported that American ginseng attenuates hyperglycemia and may present itself as a supplement to diabetes therapy. However, the lack of standardization in the usage of ginseng root leads to inconclusive results when applied to diabetes treatment. The mechanisms of American ginseng root in the treatment of diabetes remains a mystery. This greatly limits the effective utilization of American ginseng in facilitating diabetic therapy.

In North America, a high proportion of pregnant women use herbal medications including North American ginseng. This medicinal plant contains high amounts of triterpene saponins (ginsenosides), which are the main bioactive compounds. It is important to assess ginseng’s impact on all reproductive functions to ensure the safety of pregnant women and fetuses.

Abstract Oriental ginseng (Panax ginseng C.A.

Abstract (sommario):

Both ginseng and American ginseng are world-famous traditional medicines with multiple bioactivities. The deep dormancy of their seeds causes serious problems in artificial cultivation. However, little is known about the physiological mechanism of seed dormancy and how to shorten the seed dormancy period for these two plant species. An experiment was conducted to determine whether endosperm removal would promote embryo development in ginseng and American ginseng and if in vitro embryos would suffer nutrient deficiency during seedling establishment. The results show that excised embryos develop

Abstract The AOAC INTERNATIONAL guidelines for validation of botanical identification methods were applied to the detection of Asian Ginseng [Panax ginseng (PG)] as an adulterant for American Ginseng [P. quinquefolius (PQ)] using spectral fingerprints obtained by flow injection mass spectrometry (FIMS). Samples of 100% PQ and 100% PG were physically mixed to provide 90, 80, and 50% PQ. The multivariate FIMS fingerprint data were analyzed using soft independent modeling of class analogy (SIMCA) based on 100% PQ. The Q statistic, a measure of the degree of non-fit of the test samples with the ca

Abstract (sommario):

The fungus Alternaria panax Whetzel causes leaf and stem blight of American ginseng ( Panax quinquefolius L.). Six isolates of A. panax, collected from widely separated ginseng-growing areas in North America, were characterized on the basis of their colony and conidial morphology, molecular characteristics, and virulence. Colony morphology on standard media and conidial morphology based on light microscopy showed some variation with geographic locality: Wisconsin isolates were slightly different from Ontario and British Columbia isolates. Isolates from each locality were equally virulent on Am

Abstract (sommario):

American ginseng root displays the ability to achieve glucose homeostasis both experimentally and clinically but the unknown mechanism used by ginseng to achieve its therapeutic effects on diabetes limits its application. Disruption in the insulin secretion of pancreatic β cells is considered the major cause of diabetes. A mitochondrial protein, uncoupling protein-2 (UCP-2) has been found to play a critical role in insulin synthesis and β cell survival. Our preliminary studies found that the extracts of American ginseng inhibit UCP-2 expression which may contribute to the ability of ginseng pr

Abstract (sommario):

Premature ovarian failure (POF) is defined as lost ovarian functions before the age of 40. Three possible molecular markers (PLA2G4A,miR-29a, andmiR-144) have been identified in our previous study by integrated analysis of mRNA and miRNA expression profiles. The present study aimed to evaluate American ginseng root’s protective potential against POF by studying transcriptional and protein variations between American ginseng treatments and controls in rats. 4-Vinylcyclohexene diepoxide (VCD) was administered to rats for 14 days to induce POF. Additionally, American ginseng was administered to P

Abstract (sommario):

Eccentric muscle contractions such as those experienced during downhill running are associated with inflammation, delayed-onset of muscle soreness, myofiber damage, and various functional deficits. North American ginseng (Panax quinquefolius L.) has been reported to possess anti-inflammatory properties and thus may offset some of this exercise-induced damage. Hence, we tested the hypothesis that intervention with North American ginseng would reduce eccentric exercise-induced muscle damage and inflammation. Male Wistar rats were fed (300 mg/(kg·day)–1) of either an alcohol (AL) or aqueous (AQ)

Asian ginseng, American ginseng, and notoginseng are three major species in the ginseng family. Notoginseng is a Chinese herbal medicine with a long history of use in many Oriental countries. This botanical has a distinct ginsenoside profile compared to other ginseng herbs. As a saponin-rich plant, notoginseng could be a good candidate for cancer chemoprevention. However, to date, only relatively limited anticancer studies have been conducted on notoginseng. In this paper, after reviewing its anticancer data, phytochemical isolation and analysis of notoginseng is presented in comparison with A

Methylphenidate and American Ginseng were recognized for promising results and safe to use as a single therapy. Psycho-stimulants are commonly used and are effective in moderate to severe fatigue. The mechanism behind the evidence for methylphenidate is rebalancing dopamine neurotransmission which is altered in fatigue. The mechanism behind ginseng benefits appears to be improvement in muscle metabolism and reduction in infla

Abstract (sommario):

In the Northeast, wild American ginseng (Panax quinquefolium L.) is typically found growing in the dense shade provided by deciduous hardwood tree species such as a sugar maple, in slightly acidic soils with relatively high calcium content. Woods cultivated ginseng is often grown in forest farming agroforestry systems under similar conditions. Supplemental calcium by soil incorporation of gypsum (CaSO4·2H2O) is often recommended for woods cultivated ginseng. The objective of this study was to investigate the effects of this practice on soil chemical properties, plant growth and quality of Amer

A total of 420 random decamers were initially screened against DNA from four ginseng plants and 78.8% of them generated RAPD fragments. Thirty-six of the decamers that generated highly repeatable polymorphic RAPD markers were selected for further RAPD analysis of the ginseng population. With these primers, 352 discernible DNA fragments were produced from DNA of 48 ginseng p
