Abstract
American ginseng (Panax quinquefolius) has gained recognition as a medicinal and functional food homologous product with several pharmaceutical, nutritional, and industrial applications. However, the key regulators involved in ginsenoside biosynthesis, the spatiotemporal distribution characteristics of ginsenosides, and factors influencing ginsenosides are largely unknown, which make it challenging to enhance the quality and chemical extraction processes of the cultivated American ginseng. This review presents an overview of the pharmacological effects, biosynthesis and spatiotemporal distribution of ginsenosides, with emphasis on the impacts of biotic and abiotic factors on ginsenosides in American ginseng. Modern pharmacological studies have demonstrated that American ginseng has neuroprotective, cardioprotective, antitumor, antidiabetic, and anti-obesity effects. Additionally, most genes involved in the upregulation of ginsenoside biosynthesis have been identified, while downstream regulators (OSCs, CYP450, and UGTs) require further investigation. Futhermore, limited knowledge exists regarding the molecular mechanisms of the impact of biotic and abiotic factors on ginsenosides. Notably, the nonmedicinal parts of American ginseng, particularly its flowers, fibrous roots, and leaves, exhibit higher ginsenoside content than its main roots and account for a considerable amount of weight in the whole plant, representing promising resources for ginsenosides. Herein, the prospects of molecular breeding and metabolic engineering based on multi-omics to improve the unstable quality of cultivated American ginseng and the shortage of ginsenosides are proposed. This review highlights the gaps in the current research on American ginseng and proposes solutions to address these limitations, providing a guide for future investigations into American ginseng ginsenosides.

Abstract
Colorectal cancer (CRC) is among the most common malignant diseases with high morbidity and mortality rates. Ginseng and its major extracts, ginsenosides, have been used in medical fields for thousands of years. In particular, their huge anti-cancer potential has drawn a great deal of attention in recent years. There is a large body of evidence that has shown that ginseng and its extracts could significantly inhibit tumor development and progression by suppressing cell proliferation, tumor growth, invasion and metastasis, inducing tumor cell apoptosis, regulating tumor-associated immune responses, and improving the therapeutic effect of chemotherapy. Notably, different subtypes of ginsenosides, even those extracted from the same ginseng, have exhibited distinct anti-cancer functions through different mechanisms. Over the past few years, a large number of studies have focused on how ginseng or various ginsenosides influence CRC development. Therefore, the roles and the potential of ginseng and ginsenosides in the treatment of CRC are summarized in this review. In addition, the biochemical properties of ginseng and ginsenosides are also briefly described.

Abstract
Ginsenoside Re is a protopanaxatriol-type saponin extracted from the berry, leaf, stem, flower bud, and root of Panax ginseng. In recent years, ginsenoside Re (Re) has been attracting attention as a dietary phytochemical. In this review, studies on Re were compiled by searching a combination of keywords, namely “pharmacology,” “pharmacokinetics,” and “toxicology,” in the Google Scholar, NCBI, PubMed, and Web of Science databases. The aim of this review was to provide an exhaustive overview of the pharmacological activities, pharmacokinetics, and toxicity of Re, focusing on clinical evidence that has shown effectiveness in specific diseases, such as diabetes mellitus, nervous system diseases, inflammation, cardiovascular disease, and cancer. Re is also known to eliminate virus, enhance the immune response, improve osteoporosis, improve skin barrier function, enhance intracellular anti-oxidant actions, regulate cholesterol metabolism, alleviate allergic responses, increase sperm motility, reduce erectile dysfunction, promote cyclic growth of hair follicles, and reduce gastrointestinal motility dysfunction. Furthermore, this review provides data on pharmacokinetic parameters and toxicological factors to examine the safety profile of Re. Such data will provide a theoretical basis and reference for Re-related studies and future applications.

J Food Biochem 2022; 46:e14042. [PMID: 34981530 DOI: 10.1111/jfbc.14042] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 11/05/2021] [Accepted: 11/08/2021] [Indexed: 12/28/2022]
Abstract
American ginseng berry (AGB) is a new medicinal source. Total saponins of American ginseng berry (TSAGB) are the main active ingredients. The effects and active saponins of TSAGB on myocardial ischemia (MI) rats were evaluated for the first time. First, there were 69 saponins identified or tentatively characterized by Ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q/TOF-MS/MS) combined with UNIFI platform, among which, about 28 saponins were first identified in AGB. Second, MI model was established by ligating left coronary artery. It has been demonstrated that TSAGB could prevent the ST-segment elevation, reduce myocardial infarct size and levels of aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH), malondialdehyde (MDA), and elevate the superoxide dismutase (SOD) level. Finally, network pharmacology combined with molecular docking to screen out four active saponins (ginsenoside Re, Rb3 , Rg3 , and PF11 ) and five key targets (SOD1, LDHA, CKB, GOT2, and ROS1) closely related to MI. PRACTICAL APPLICATIONS: This study enriches the chemical composition of TSAGB, and provides a basis for clarifying the pharmacological substances for anti-myocardial ischemia. TSAGB might be a potential anti-myocardial ischemia agent. The effect might be related to alleviating oxidative stress.

Comparative Analysis of Panax ginseng Berries from Seven Cultivars Using UPLC-QTOF/MS and NMR-Based Metabolic Profiling. Biomolecules 2019; 9:biom9090424. [PMID: 31466413 PMCID: PMC6770912 DOI: 10.3390/biom9090424] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2019] [Revised: 08/27/2019] [Accepted: 08/27/2019] [Indexed: 11/16/2022] Open
Abstract
The commercial use of Panax ginseng berries is increasing as P. ginseng berries are known to contain large amounts of ginsenosides, and many pharmacological activities have been reported for the various ginsenosides. For the proper use of P. ginseng berries, it is necessary to study efficient and accurate quality control and the profiling of the overall composition of each cultivar. Ginseng berry samples from seven cultivars (Eumseung, Chung-buk Province, Republic of Korea) were analyzed using ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-QTOF/MS) for profiling of the ginsenosides, and high-resolution magic-angle-spinning nuclear magnetic resonance (HR-MAS NMR) spectroscopy for profiling of the primary metabolites. Comparing twenty-six ginsenoside profiles between the variant representatives and between the violet-stem variant, Kumpoong and Sunwon were classified. In the case of primary metabolites, the cultivars Kumpoong and Gopoong were classified. As a result of correlation analyses of the primary and secondary metabolites, in the Gopoong cultivar, the metabolism was found to lean toward energy metabolism rather than ginsenoside synthesis, and accumulation of osmolytes was low. The Gopoong cultivar had higher levels of most of the amino acids, such as arginine, phenylalanine, isoleucine, threonine, and valine, and it contained the highest level of choline and the lowest level of myo-inositol. Except for these, there were no significant differences of primary metabolites. In the Kumpoong cultivar, the protopanaxatriol (PPT)-type ginsenosides, ginsenoside Re and ginsenoside Rg2, were much lower than in the other cultivars, while the other PPT-type ginsenosides were inversely found in much higher amounts than in other cultivars. The Sunwon cultivar showed that variations of PPT-type ginsenosides were significantly different between samples. However, the median values of PPT-type ginsenosides of Sunwon showed similar levels to those of Kumpoong. The difference in primary metabolites used for metabolism for survival was found to be small in our results. Our data demonstrated the characteristics of each cultivar using profiling data of the primary and secondary metabolites, especially for Gopoong, Kumpoong, and Sunwon. These profiling data provided important information for further research and commercial use.

Abstract
The root of Asian ginseng (Panax ginseng C.A. Meyer) has been used for centuries in Oriental medicine to improve general well-being and to relieve various medical conditions. It is commonly understood that ginsenosides are responsible for the pharmacological activities of ginseng. Compared to the root of ginseng, studies on the berry are considerably limited. In this study, we evaluated the effects of polysaccharides from Asian ginseng berries on plasma lipid levels, chemically-induced enteric inflammation and neoplasm, and cancer chemoprevention in different experimental models. We tested two polysaccharide preparations: regular ginseng berry polysaccharide extract (GBPE) and ginseng berry polysaccharide portion (GBPP, removed MV [Formula: see text]). We first observed that both oral GBPE and oral GBPP significantly reduced plasma cholesterol and triglycerides levels in a dose-related manner in ob/ob mice, without obvious body weight changes. Then, in AOM/DSS-induced acute colitis mice, GBPE and GBPP significantly ameliorated the increased gut disease activity index and inhibited the reduction of the colon length. Further, the berry polysaccharides significantly suppressed chemically-induced pro-inflammatory cytokine levels. This is consistent with the observation that GBPE and GBPP attenuated tumorigenesis in mice by significantly and dose-dependently reducing tumor load. Finally, in vitro HCT-116 and HT-29 human colon cancer cells were used. While these berry preparations had better antiproliferation effects on the HCT-116 than the HT-29 cells, the GBPE had significantly stronger inhibitory effects than GBPP. The observed in vitro GBPE's effect could contribute to the actions of its small-molecule non-polysaccharide compounds due to their direct antiproliferative activities. Results obtained from the present study suggest that ginseng berry polysaccharides may have a therapeutic role in the management of high lipid levels, enteric inflammation, and colon malignancies.

Abstract
Recently, most anticancer drugs are derived from natural resources such as marine, microbial, and botanical sources, but the low success rates of chemotherapies and the development of multidrug resistance emphasize the importance of discovering new compounds that are both safe and effective against cancer. Ginseng types, including Asian ginseng, American ginseng, and notoginseng, have been used traditionally to treat various diseases, due to their immunomodulatory, neuroprotective, antioxidative, and antitumor activities. Accumulating reports have shown that ginsenosides, the major active component of ginseng, were helpful for tumor treatment. 20(S)-Protopanaxadiol (PDS) and 20(S)-protopanaxatriol saponins (PTS) are two characteristic types of triterpenoid saponins in ginsenosides. PTS holds capacity to interfere with crucial metabolism, while PDS could affect cell cycle distribution and prodeath signaling. This review aims at providing an overview of PTS and PDS, as well as their metabolites, regarding their different anticancer effects with the proposal that these compounds might be potent additions to the current chemotherapeutic strategy against cancer.

Abstract
American ginseng (Panax quinquefolius L.) is one of the most commonly used herbal medicines in the West. It has been reported to possess significant antitumor effects that inhibit the process of carcinogenesis. However, the mechanisms underlying its anticancer effects remain largely unresolved. In this study, we investigated the cancer chemopreventive effects of American ginseng on the progression of high fat (HF) diet-enhanced colorectal carcinogenesis with a genetically engineered Apc(Min/+) mouse model. The metabolic alterations in sera of experimental mice perturbed by HF diet intervention as well as the American ginseng treatment were measured by gas chromatography time-of-flight mass spectrometry (GC-TOFMS) and liquid chromatography time-of-flight mass spectrometry (LC-TOFMS) analysis. American ginseng treatment significantly extended the life span of the Apc(Min/+) mouse. Significant alterations of metabolites involving amino acids, organic acids, fatty acids, and carbohydrates were observed in Apc(Min/+) mouse in sera, which were attenuated by American ginseng treatment and concurrent with the histopathological improvement with significantly reduced tumor initiation, progression and gut inflammation. These metabolic changes suggest that the preventive effect of American ginseng is associated with attenuation of impaired amino acid, carbohydrates, and lipid metabolism. It also appears that American ginseng induced significant metabolic alterations independent of the Apc(Min/+) induced metabolic changes. The significantly altered metabolites induced by American ginseng intervention include arachidonic acid, linolelaidic acid, glutamate, docosahexaenoate, tryptophan, and fructose, all of which are associated with inflammation and oxidation. This suggests that American ginseng exerts the chemopreventive effects by anti-inflammatory and antioxidant mechanisms.

Abstract
Ginsenoside compound K (C-K) is an intestinal microbiota metabolite of ginsenoside Rb1, a major constituent in American ginseng. However, previous ginseng anti-cancer observations were largely focused on ginseng parent compounds but not metabolites, and anti-colorectal cancer studies on C-K were limited. This study investigated the anti-proliferative effects of C-K when compared to those of Rb1, and the related mechanisms of action, in HCT-116 and SW-480 colorectal cancer cells. The effects of Rb1 and C-K on the proliferation of HCT-116 and SW-480 human colorectal cancer cells were compared using an MTS assay. Cell cycle and cell apoptosis were assayed using flow cytometry. Enzymatic activities of caspases were determined by colorimetric assay, and interactions of C-K and caspases were explored by docking analysis. C-K showed significant anti-proliferative effects in HCT-116 and SW-480 cells at concentrations of 30-50 µM. At the same concentrations, Rb1 did not show any effects, while C-K arrested the cells in the G1 phase, and significantly induced cell apoptosis. Compared to HCT-116 (p53 wild-type), the p53 mutant cell line SW-480 was more sensitive to C-K as assessed by cell cycle regulation and apoptosis induction. C-K activated expression of caspases 8 and 9, consistent with docking analysis. The docking data suggested that C-K forms hydrogen bonds with Lys253, Thr904 and Gly362 in caspase 8, and with Thr62, Ser63 and Arg207 in caspase 9. C-K, but not its parent ginsenoside Rb1, showed significant anti-proliferative and pro-apoptotic effects in human colorectal cancer cells. These results suggest that C-K could be a potentially effective anti-colorectal cancer agent.

Abstract
Ginsenoside F2 (F2) was assessed for its antiproliferative activity against breast cancer stem cells (CSCs). F2 induced apoptosis in breast CSCs by activating the intrinsic apoptotic pathway and mitochondrial dysfunction. Concomitantly, F2 induced the formation of acidic vesicular organelles, recruitment of GFP-LC3-II to autophagosomes, and elevation of Atg-7 levels, suggesting that F2 initiates an autophagic progression in breast CSCs. Treatment with an inhibitor of autophagy enhanced F2-induced cell death. Our findings provide new insights into the anti-cancer activity of F2 and may contribute to the rational use and pharmacological study of F2.
