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 metabolic distinction between American ginseng and Asian ginseng in diet-induced obese (DIO) mice. The results show that American ginseng and Asian ginseng alleviate glucose and lipid metabolism disorder in DIO mice. A total of 45 differential metabolites were confirmed between the drug-naïve and American ginseng group, and 32 metabolites were confirmed between the drug-naïve and Asian ginseng group. Metabolic pathways analysis shows that these two ginsengs treatment dynamic rectifies metabolic disorder in DIO mice mainly via regulating linoleic acids metabolism, cysteine and methionine metabolism and biosynthesis of unsaturated fatty acid. Moreover, American ginseng’s specific function in monitoring the carnitines and taurine/hypotaurine metabolism might make it more effective in meliorating lipids metabolism disorder than Asian ginseng.

Abstract (sommario):

TLC, DCC and HPLC were used to study the ginsenoside composition of the main root, lateral root, rhizomem leaves and seeds of Panax ginseng cultivated in Jilin, China. Each of these methods has advantages of its own and the ensemble reveal the special features of Jilin ginseng. Total saponin content of various plant parts in Jilin ginseng showed a mid-range value as compared to those in ginsengs reported in literature. Fresh as well as sun-dried specimens from the same batch possessed a high percentage of Rg1 in the main root and this might account for the traditional preference of this plant part despite its lowest percentage of saponin in the whole plant. Large amounts of polar saponins were also observed in roots and rhizome of fresh Jilin ginseng, the nature and significance of which remained to be investigated.

Abstract (sommario):

Ginseng has been shown to be effective on cardiac dysfunction. Recent evidence has highlighted the mediation of peroxisome proliferator-activated receptors (PPARs) in cardiac function. Thus, we are interested to investigate the role of PPARδin ginseng-induced modification of cardiac contractility. The isolated hearts in Langendorff apparatus and hemodynamic analysis in catheterized rats were applied to measure the actions of ginsengex vivoandin vivo. In normal rats, ginseng enhanced cardiac contractility and hemodynamicdP/dtmaxsignificantly. Both actions were diminished by GSK0660 at a dose enough to block PPARδ. However, ginseng failed to modify heart rate at the same dose, although it did produce a mild increase in blood pressure. Data of intracellular calcium level and Western blotting analysis showed that both the PPARδexpression and troponin I phosphorylation were raised by ginseng in neonatal rat cardiomyocyte. Thus, we suggest that ginseng could enhance cardiac contractility through increased PPARδexpression in cardiac cells.

Abstract (sommario):

The grading of ginseng (Panax ginseng) including the evaluation of internal quality attributes is essential in the ginseng industry for quality control. Assessment for inner whitening, a major internal disorder, must be conducted when identifying high quality ginseng. Conventional methods for detecting inner whitening in ginseng root samples use manual inspection, which is time-consuming and inaccurate. This study develops an internal quality measurement technique using near-infrared transmittance spectral imaging to evaluate inner whitening in ginseng samples. Principle component analysis (PCA) was used on ginseng hypercube data to evaluate the developed technique. The transmittance spectra and spectral images of ginseng samples exhibiting inner whitening showed weak intensity characteristics compared to normal ginseng in the region of 900–1050 nm and 1150–1400 nm respectively, owing to the presence of whitish internal tissues that have higher optical density. On the basis of the multivariate analysis method, even a simple waveband ratio image has the great potential to quickly detect inner whitening in ginseng samples, since these ratio images show a significant difference between whitened and non-whitened regions. Therefore, it is possible to develop an efficient and rapid spectral imaging system for the real-time detection of inner whitening in ginseng using minimal spectral wavebands. This novel strategy for the rapid, cost-effective, non-destructive detection of ginseng’s inner quality can be a key component for the automation of ginseng grading.

Abstract (sommario):

In this study, the feasibility of near infrared reflectance spectroscopy for the quality evaluation of the main bioactive compounds, ginsenosides, in Panax ginseng was examined. Second derivative NIR spectra of standard reagents of ginsenoside Rg1, Re, Rb1, Rc, Rb2 and Rd were used for analysis. Characteristic bands were observed at around 5250 cm−1 in the spectra of ginsenoside Rg1 group (including Rg1 and Re); however, this was not to be observed on the spectra of ginsenoside Rb1 group (including Rb1, Rc, Rb2 and Rd). PLS regression models were constructed of air-dry ginseng powder samples and ginsenoside content in ginsengs was determined by HPLC methods. The calibration models covered various types of ginseng (white ginseng, red ginseng and bleached ginseng) from various cultivated areas (Japan, China and Korea) and were well established for each kind of ginsenoside. It was shown that NIR spectroscopy can be used for the accurate prediction of ginsenoside.

Abstract (sommario):

In this study, we investigated the effects of methanolic extracts of white ginseng (Panax ginseng C.A. MEYER) and two kinds of heat-treated ginseng made by steaming fresh ginseng at 100°C for 3 hours (HTG-100) or 120°C for 3 hours (HTG-120) on the cell growth of human fibroblasts. All of the tested ginseng extracts stimulated cell growth, although the effect of HTG-120 was weaker than that of the other extracts. However, none of the ginseng extracts exhibited any effect on the growth of old cells with a population doubling level (PDL) of 48.7. Flow cytometric analysis showed that ginseng extracts raised the population of cells in G 0/ G 1 phase after treatment for 24 hours, but did not exert any effect after treatment for 48 hours. These results suggest that ginsengs exert their cell growth-promoting action mainly on younger cells at an early stage of the cell cycle, and that this effect is closely associated with an increase in the population of cells in the G 0/ G 1 phase.

Abstract (sommario):

SPL (SQUAMOSA promoter binding protein-like) gene family is specific transcription factor in the plant that have an important function for plant growth and development. Although the SPL gene family has been widely studied and reported in many various plant species from gymnosperm to angiosperm, there are no systematic studies and reports about the SPL gene family in Panax ginseng C. A. Meyer. In this study, we conducted transcriptome-wide identification, evolutionary analysis, structure analysis, and expression characteristics analysis of SPL gene family in Panax ginseng by bioinformatics. We annotated the PgSPL gene family and found that they might involve in multiple functions including encoding structural proteins, but the main function were still focused on the binding function. The result showed that 106 PgSPL transcripts were classified into two clades - A and B, both of which respectively consisted of three groups. Besides, we profiled PgSPL transcripts’ genotypic, temporal, and spatial expression characteristics. Furthermore, we calculated the correlation of PgSPL transcripts in the 14 tissues of a 4 years old ginseng and 42 farmers’ cultivars farmers’ cultivars of 4 years old ginsengs’ roots with both results showing that SPL transcripts formed a single network, which indicated that PgSPLs inter-coordinated when performing their functions. What’s more, we found that most PgSPL transcripts tended to express in older ginseng instead of younger ginseng, which was not only reflected in the expression of more types of SPL transcripts in older ginseng, but also in the higher expression of SPL transcripts in older ginseng. Additionally, we found that four PgSPL transcripts were only massively expressed in roots. According to PgSPL transcripts’ expression characteristics, we found that PgSPL23-35 and PgSPL24-09 were most proper two transcripts to further study as ginseng age’s molecular marker. These results provide the basis for further elucidation of the PgSPL transcripts’ biological function in ginseng and ginseng genetics improvement and gene breeding in the future.

Abstract (sommario):

Recently Panax ginseng has been grown as a secondary crop under a pine tree canopy in New Zealand (NZ). The aim of the study is to compare the average content of ginsenosides from NZ-grown ginseng and its original native locations (China and Korea) grown ginseng. Ten batches of NZ-grown ginseng were extracted using 70% methanol and analyzed using LC-MS/MS. The average content of ginsenosides from China and Korea grown ginseng were obtained by collecting data from 30 and 17 publications featuring China and Korea grown ginseng, respectively. The average content of total ginsenosides in NZ-grown ginseng was 40.06 ± 3.21 mg/g (n = 14), which showed significantly (p < 0.05) higher concentration than that of China grown ginseng (16.48 ± 1.24 mg/g, n = 113) and Korea grown ginseng (21.05 ± 1.57 mg/g, n = 106). For the individual ginsenosides, except for the ginsenosides Rb2, Rc, and Rd, ginsenosides Rb1, Re, Rf, and Rg1 from NZ-grown ginseng were 2.22, 2.91, 1.65, and 1.27 times higher than that of ginseng grown in China, respectively. Ginsenosides Re and Rg1 in NZ-grown ginseng were also 2.14 and 1.63 times higher than ginseng grown in Korea. From the accumulation of ginsenosides, New Zealand volcanic pumice soil may be more suitable for ginseng growth than its place of origin.

Abstract (sommario):

Two quantitative methods (−ESI full scan and −ESI PRM MS) were developed to analyze ginsenosides in ginseng stem-leaf by using UPLC-Q-Exactive Orbitrap/MS. By means of −ESI PRM MS method, the contents of eighteen ginsenosides in Asian ginseng stem-leaf (ASGSL) and American ginseng stem-leaf (AMGSL) were analyzed. The principal component analysis (PCA) model was built to discriminate Asian ginseng stem-leaf (ASGSL) from American ginseng stem-leaf (AMGSL) based on −ESI PRM MS data, and six ginsenosides (F11, Rf, R2, F1, Rb1, and Rb3) were obtained as the markers. To further explore the differences between cultivated ginseng stem-leaf and forest ginseng stem-leaf, the partial least squares-discriminant analysis (PLS-DA) model was built based on −ESI full scan data. And twenty-six markers were selected to discriminate cultivated ginseng stem-leaf (CGSL) from forest ginseng stem-leaf (FGSL). This study provides reliable and effective methods to quantify and discriminate among different types of ginseng stem-leaf in the commercial market.

Abstract (sommario):

[Truncated abstract] Traditional medicines are used by millions of people throughout the world as their primary source of medical care. A range of materials are in used traditional medicines including plant and animal parts. Even though the traditional medicine trade is estimated to be worth sixty billion dollars annually the trade remains largely unregulated. Unscrupulous practices by vendors to increase their profit margins such as substituting and adulterating expensive material with cheaper varieties go unchecked. This can be dangerous to consumers because some substitutions involve poisonous material. Also, animal parts from endangered species can find their way into traditional medicines, therefore there needs to be a way to identify them in traditional medicines to prosecute poachers. The traditional techniques used for the identification of material used in Traditional Chinese Medicine (TCM) include, morphological, histological, chemical and immunological analysis. However, these techniques have their limitations. This makes applying multiple techniques essential to provide thorough authentication of the material. DNA profiling provides a technique well suited to analysing material used in TCM. DNA profiling is advantageous over other techniques used to authenticate material used in TCM because it requires only a small sample amount, can determine the cultivator, be used on all forms of TCM and potentially distinguish the components of mixtures. ... Therefore, profiles of different species/individual are different and species? can be distinguished. Commercially sold traditional medicines are processed which is likely to degrade the DNA of the sample making extraction and amplification difficult. Here an organic Phenol:Chloroform extraction technique extracted DNA from commercial dried root samples. The extracted DNA was amplifiable using RAPD primers. The RAPD primers used here produced enough polymorphic bands to distinguish different plant species. They were used to distinguish commercial samples that were sold as three different species within the Panax genus, Panax ginseng, Panax quinquefolium and Panax notoginseng and genetically unrelated plant material; Potato and Eleutherococcus senticosus. Liquid samples and mixtures were also profiled with the RAPD primers to determine whether the RAPD primers provide enough distinguishing ability to analyse these forms of TCM. DNA was extracted from the liquid samples, one a ginseng drink and the other an ginseng extractum. However, there was no reliability in the production of PCR products. The analysis of the mixture samples found that not enough polymorphic bands were produced by the RAPD primers used here to identify Panax species within mixtures of two Panax species. While when P. ginseng was mixed with a genetically unrelated sample there was enough polymorphism to differentiate the two samples in the mixture. The results of this research show that RAPD analysis provides a simple and inexpensive technique to begin analysis of materials used in TCM. Using RAPD analysis it is possible to distinguish Panax plant species from each other. However, the RAPD primers used here did not provide enough reproducibility or polymorphism to analyse liquid and mixtures of Panax species plants.

Abstract (sommario):

Writing Nature is the first full-length ecocritical study of Cold War American literature. The book analyses the function and representation of Nature in a wide range of Cold War texts, and reveals the prevalence of portrayals of Nature as an infinite, interdependent ecological system in American literature written between 1945 and 1971. It also highlights the Cold War’s often overlooked role in environmental history, and argues for the repositioning of Rachel Carson’s Silent Spring (1962) within what is shown to be a developing trend of ecological presentations of Nature in literature written after 1945. Ecocritical analysis is combined with historicist research to expose the unacknowledged role of a globally diverse range of non-Western and non-Anglocentric philosophies in shaping Cold War writers’ ecological presentations of Nature, including Sufism, Taoism and Zen Buddhism. The book contains chapters on J. D. Salinger, Jack Kerouac and Allen Ginsberg, Paul Bowles and Mary McCarthy. It also introduces the regional writer Peggy Pond Church, exploring the synergies between the depictions of Nature in her writings and in those of her neighbour and correspondent, the atomic scientist J. Robert Oppenheimer. The place and function of Nature in each writer’s work is assessed in relation to the most recent developments in the field of ecocriticism, and each of the book’s six author case studies is investigated through a combination of textual analysis and detailed archival and historicist research.

Abstract (sommario):

Deterioration of a rotordynamic system changes its modal properties. This paper initiates a study of the degree to which such changes can be detected by monitoring modal metrics obtained by a modern technique for experimental modal analysis (EMA). The eigenvalues and residues associated with a complex modal description of the frequency response are identified by processing response data derived from an analytical model. This model, which features an elastic shaft with attached rigid rotor and supported by hydrodynamic bearings, was previously used by Wagner and Ginsberg [Proc. of the 23rd International Modal Analysis Conf. (IMAC), forthcoming, 2005] to explore the merits of using standard or directional frequency response functions to perform EMA. The techniques used there, specfically the original version of the Algorithm of Mode Isolation (AMI) for FRFs and Two-Sided AMI for dFRFs, are used to extract the modal properties from the model’s frequency domain response. The modal eigenvalues and residues are identified for a range of bearing clearances within the limit of acceptable wear. One set of metrics that are considered describes the behavior of the system’s eigenvalues as clearance increases. Another set of metrics describes the modal residue factors, which depend on the drive and response locations. A defect is considered to be detectable if the change in the value of a metric due to deterioration exceeds the uncertainty in that metric’s value associated with the inexact nature of EMA. Although the eigenvalues are identified with great accuracy, they are found to be relatively insensitive to bearing clearance, so that metrics derived from them do not meet the detectability criterion. In contrast, the residue values are identified less accurately, but they are highly sensitivity to the clearance. It is concluded that metrics describing the behavior of the modal residue factors can unambiguously indicate bearing wear that is large, but still acceptable for continued operation. It also is found that it is preferable to monitor the residues obtained by processing standard FRFs using the original AMI version, rather than using Two-Sided AMI to process dFRFs.

Abstract (sommario):

Abstract Noise and vibration reduction is a critical concern in planetary gear applications. During the design process, system parameters are varied to evaluate alternative design choices, avoid resonances, optimize load distribution, and reduce weight. It is important to characterize the effects of parameter variations on the natural frequencies and vibration modes for effective vibration tuning. In planetary gear dynamic models (Figure 1), the key design parameters include the mesh stiffness, support/bearing stiffness, component mass, and moment of inertia. Some plots of natural frequencies versus planetary gear parameters are presented by Cunliffe et al. (1974), Botman (1976), Kahraman (1994), and Saada and Velex (1995). Lin and Parker (1999a) analytically characterized the unique, highly-structured properties of planetary gear natural frequency spectra and vibration modes. They also derived simple, closed-form expressions for the sensitivities of natural frequencies and vibration modes to these parameters (Lin and Parker, 1999b). The natural frequency plots in the above literature show natural frequency veering phenomena where two eigenvalue loci approach each other as a parameter is varied but then abruptly veer away like two similar charges repelling (Figure 2a). The phenomenon has been extensively studied (Leissa, 1974; Perkins and Mote, 1986; Pierre, 1988; Chen and Ginsberg, 1992; Happawana et al., 1998). The vibration modes of the veering eigenvalues are strongly coupled and undergo dramatic changes in the veering neighborhood. Eigenvalue veering is also related to mode localization that can occur when disorder is introduced into nominally symmetric systems like turbine blades, space antennae, multi-span beams and other structures (Pierre, 1988). In the case of especially sharp veering, it is sometimes difficult to distinguish between intersection and veering just by observing eigenvalue plots. Curve veering/crossing complexity obstructs the tracing of eigenvalue loci under parameter changes. Also, when multiple curves veer or intersect close together (Figure 3), strong modal coupling (and associated operating condition response changes) occurs that is not identifiable from frequency loci plots. The objective of this work is to analytically characterize the rules of eigenvalue veering in planetary gear vibration. The special veering patterns derived here help to trace natural frequencies and examine impacts of design parameters on vibration. These veering patterns, combined with the unique modal properties (Lin and Parker, 1999a) and the eigensensitivies analysis (Lin and Parker, 1999b), provide designers considerable insight into planetary gear free vibration.
