A comprehensive and systemic review of ginseng-based nanomaterials: Synthesis, targeted delivery, and biomedical applications. Med Res Rev 2023; 43:1374-1410. [PMID: 36939049 DOI: 10.1002/med.21953] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 11/22/2022] [Accepted: 02/26/2023] [Indexed: 03/21/2023]
Abstract
Among 17 Panax species identified across the world, Panax ginseng (Korean ginseng), Panax quinquefolius (American ginseng), and Panax notoginseng (Chinese ginseng) are highly recognized for the presence of bioactive compound, ginsenosides and their pharmacological effects. P. ginseng is widely used for synthesis of different types of nanoparticles compared to P. quinquefolius and P. notoginseng. The use of nano-ginseng could increase the oral bioavailability, membrane permeability, and thus provide effective delivery of ginsenosides to the target sites through transport system. In this review, we explore the synthesis of ginseng nanoparticles using plant extracts from various organs, microbes, and polymers, as well as their biomedical applications. Furthermore, we highlight transporters involved in transport of ginsenoside nanoparticles to the target sites. Size, zeta potential, temperature, and pH are also discussed as the critical parameters affecting the quality of ginseng nanoparticles synthesis.

Wang Y, Han Q, Zhang S, Xing X, Sun X. New perspective on the immunomodulatory activity of ginsenosides: Focus on effective therapies for post-COVID-19. Biomed Pharmacother 2023; 165:115154. [PMID: 37454595 DOI: 10.1016/j.biopha.2023.115154] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 07/09/2023] [Accepted: 07/11/2023] [Indexed: 07/18/2023] Open
Abstract
More than 700 million confirmed cases of Coronavirus Disease-2019 (COVID-19) have been reported globally, and 10-60% of patients are expected to exhibit "post-COVID-19 symptoms," which will continue to affect human life and health. In the absence of safer, more specific drugs, current multiple immunotherapies have failed to achieve satisfactory efficacy. Ginseng, a traditional Chinese medicine, is often used as an immunomodulator and has been used in COVID-19 treatment as a tonic to increase blood oxygen saturation. Ginsenosides are the main active components of ginseng. In this review, we summarize the multiple ways in which ginsenosides affect post-COVID-19 symptoms, including inhibition of lipopolysaccharide, tumor necrosis factor signaling, modulation of chemokine receptors and inflammasome activation, induction of macrophage polarization, effects on Toll-like receptors, nuclear factor kappa-B, the mitogen-activated protein kinase pathway, lymphocytes, intestinal flora, and epigenetic regulation. Ginsenosides affect virus-mediated tissue damage, local or systemic inflammation, immune modulation, and other links, thus alleviating respiratory and pulmonary symptoms, reducing the cardiac burden, protecting the nervous system, and providing new ideas for the rehabilitation of patients with post-COVID-19 symptoms. Furthermore, we analyzed its role in strengthening body resistance to eliminate pathogenic factors from the perspective of ginseng-epidemic disease and highlighted the challenges in clinical applications. However, the benefit of ginsenosides in modulating organismal imbalance post-COVID-19 needs to be further evaluated to better validate the pharmacological mechanisms associated with their traditional efficacy and to determine their role in individualized therapy.

Abstract
Drug resistance is a major concern nowadays, and finding alternatives of the well-known antibiotic is necessary. Green nanoparticles are emerging as a tenable alternative to this with a large spectrum of activity. The present manuscript describes an eco-friendly approach for green synthesis of silver nanoparticles from both in vitro and in vivo leaf extract of Coleus forskohlii. Leaf extracts were used in synthesis of nanoparticles which were further analyzed through UV-Vis, dynamic light scattering, energy-dispersive spectroscopy, and transmission electron microscopy. Antimicrobial activity of silver nanoparticles alone, as well as crude extract of the plant itself, was carried out against eight multidrug-resistant respiratory tract infecting pathogenic strains. Satisfactory antimicrobial activities were found with nanoparticles, in vitro and in vivo leaf extracts. However, gradually higher to lower inhibition potential against pathogenic bacterial strains was found in silver nanoparticles, in vitro and in vivo leaf extracts. Seven bioactive compounds were detected in the crude extract through gas chromatography-mass spectroscopy analysis. Results revealed that nanoparticle formation occurred in a wide range of sizes (10-50 nm) and shapes (trigonal, hexagonal, spherical, rod). The diversity in size and shape of the nanoparticles makes them biologically active. Silver nanoparticle exhibits significantly better antimicrobial activities as compared to the plant extract in case of nearly all pathogens with a maximum zone of inhibition of 15.33 ± 0.94 mm where more than 12 well-known antibiotics failed to respond. Because of this broad-spectrum activity of nanoparticles as well as the leaf extracts against life-threatening microbes, it can be used as future generation drugs.

Abstract
Introduction: Adjuvants are essential to vaccines for immunopotentiation in the elicitation of protective immunity. However, classical and widely used aluminum-based adjuvants have limited capacity to induce cellular response. There are increasing needs for appropriate adjuvants with improved profiles for vaccine development toward emerging pathogens. Carbohydrate-containing nanoparticles (NPs) with immunomodulatory activity and particulate nanocarriers for effective antigen presentation are capable of eliciting a more balanced humoral and cellular immune response.Areas covered: We reviewed several carbohydrates with immunomodulatory properties. They include chitosan, β-glucan, mannan, and saponins, which have been used in vaccine formulations. The mode of action, the preparation methods, characterization of these carbohydrate-containing NPs and the corresponding vaccines are presented.Expert opinion: Several carbohydrate-containing NPs have entered the clinical stage or have been used in licensed vaccines for human use. Saponin-containing NPs are being evaluated in a vaccine against SARS-CoV-2, the pathogen causing the on-going worldwide pandemic. Vaccines with carbohydrate-containing NPs are in different stages of development, from preclinical studies to late-stage clinical trials. A better understanding of the mode of action for carbohydrate-containing NPs as vaccine carriers and as immunostimulators will likely contribute to the design and development of new generation vaccines against cancer and infectious diseases.

Abstract
Biocompatible nanoparticles (NPs) containing polymers, lipids (liposomes and micelles), dendrimers, ferritin, carbon nanotubes, quantum dots, ceramic, magnetic materials, and gold/silver have contributed to imaging diagnosis and targeted cancer therapy. However, only some NP drugs, including Doxil® (liposome-encapsulated doxorubicin), Abraxane® (albumin-bound paclitaxel), and Oncaspar® (PEG-Asparaginase), have emerged on the pharmaceutical market to date. By contrast, several phytochemicals that were found to be effective in cultured cancer cells and animal studies have not shown significant efficacy in humans due to poor bioavailability and absorption, rapid clearance, resistance, and toxicity. Research to overcome these drawbacks by using phytochemical NPs remains in the early stages of clinical translation. Thus, in the current review, we discuss the progress in nanotechnology, research milestones, the molecular mechanisms of phytochemicals encapsulated in NPs, and clinical implications. Several challenges that must be overcome and future research perspectives are also described.

Abstract
Autoimmune and infectious diseases are the major public health issues and have gained great attention in the last few years for the search of new agents with therapeutic benefits on the host immune functions. In recent years, natural products (NPs) have been studied broadly for their multi-targeted activities under pathological conditions. Interestingly, several attempts have been made to outline the immunomodulatory properties of NPs. Research on in-vitro and in-vivo models have shown the immunomodulatory activity of NPs, is due to their antiinflammatory property, induction of phagocytosis and immune cells stimulation activity. Moreover, studies on humans have suggested that phytomedicines reduce inflammation and could provide appropriate benefits either in single form or complex combinations with other agents preventing disease progression, subsequently enhancing the efficacy of treatment to combat multiple malignancies. However, the exact mechanism of immunomodulation is far from clear, warranting more detailed investigations on their effectiveness. Nevertheless, the reduction of inflammatory cascades is considered as a prime protective mechanism in a number of inflammation regulated autoimmune diseases. Altogether, this review will discuss the biological activities of plant-derived secondary metabolites, such as polyphenols, alkaloids, saponins, polysaccharides and so forth, against various diseases and their potential use as an immunomodulatory agent under pathological conditions.

Abstract
In this review, we will focus on the activity of ginsenosides on membranes and their related effects, from physicochemical, biophysical, and pharmacological viewpoints. Ginsenosides are a class of saponins with a large structural diversity and a wide range of pharmacological effects. These effects can at least partly be related to their activity on membranes which results from their amphiphilic character. Some ginsenosides are able to interact with membrane lipids and associate into nanostructures, making them possible adjuvants for vaccines. They are able to modulate membrane biophysical properties such as membrane fluidity, permeability or the formation of lateral domains with some degree of specificity towards certain cell types such as bacteria, fungi, or cancer cells. In addition, they have shown antioxidant properties which protect membranes from lipid oxidation. They further displayed some activity on membrane proteins either through direct or indirect interaction. We investigate the structure activity relationship of ginsenosides on membranes and discuss the implications and potential use as anticancer, antibacterial, and antifungal agents.

Abstract
Soyasaponins from soybean (Glycine max) represent promising new potent adjuvants for vaccine research because of their immunostimulating properties and weak hemolytic activity. In the present study, saponin microstructures of soyasaponins (soyasaponin Bb, soyasaponin Ab) with lipid components (cholesterol, DPPC (dipalmitoylphosphatidylcholine)) were designed by the lipid film method. In interaction studies between soyasaponins (soyasaponin Ab/Bb) and Langmuir monolayers (model membranes), composed of cholesterol and DPPC, marked interactions between soyasaponins and a pure cholesterol monolayer were observed. No interaction was detected for soyasaponins with a pure DPPC monolayer. The intercalation of soyasaponins in a mixed DPPC/cholesterol (3:1, w/w) monolayer was only observed for the monodesmosidic soyasaponin Bb whereas the second sugar chain of the bidesmosidic soyasaponin Ab impaired the access to the monolayer. Transmission electron microscopy was used for visualizing particle formation of soyasaponins and lipid components. Pseudo-binary systems (soyasaponin Ab/Bb, cholesterol) formed colloidal associations built up from ring-like subunits in the nanometer size range. In pseudo-ternary systems (soyasaponin, cholesterol, DPPC) soyasaponin Bb attacked the liposomal membrane by forming colloidal associations. Colloidal associations in pseudo-ternary systems with soyasaponin Ab, cholesterol and a phospholipid were only observed in the presence of PE (phosphatidylethanolamine) instead of DPPC. In an MTT assay with a HaCaT cell line (keratinocyte cell line) the cell viability was neither affected by the soyasaponins nor by the corresponding formulations. Both the pure soyasaponin solution and the saponin formulations may be promising adjuvant systems for the intradermal vaccine application. Furthermore, interaction studies between the model antigen ovalbumin and colloidal associations of saponins and cholesterol using MST (Microscale Thermophoresis) gave first indications of an antigen binding to colloidal associations. Ex vivo T-cell proliferation in the presence of soyasaponin Ab was confirmed.

Abstract
This study was to evaluate the effects of anatomical sites for vaccination on the immune responses. In experiment A, rats were subcutaneously (s.c.) immunized with a quintuplet vaccine twice at houhai acupoint, underjaw, popliteal fossa or back with a two weeks interval. The serum specific antibody levels were determined 2, 4 and 6 weeks after second immunization. Splenocytes were separated for detection of lymphocyte proliferation and cytokine mRNA expression. In experiment B, 10 female Rottweiler puppies at their age of 34 ± 2 days were subcutaneously injected with a bivalent vaccine Nobivac® Puppy DP containing live attenuated canine distemper virus (CDV) and parvovirus (CPV) for primary vaccination, and a quadrivalent vaccine Nobivac® DHPPI containing live attenuated canine distemper virus (CDV), adenovirus type 2 (CAV-2), parvovirus (CPV) and parainfluenza virus (CPIV) for subsequent vaccination at houhai acupoint (4 dogs), the shoulder (3 dogs) or the nape (3 dogs) region. Blood samples were collected at 0, 2, 4 and 6 weeks after vaccination for determination of serum specific antibody responses by ELISA. The results showed that injection of a vaccine in houhai acupoint induced the highest antibody responses in both rats and dogs. When a vaccine was injected in houhai acupoint, significantly increased proliferative responses to Con A and LPS as well as mRNA expression of IL-4, IL-10, IL-12 and IFN-γ of splenocytes were detected in rats. Therefore, houhai acupoint is recommended for injection of a vaccine to improve the immune response in dogs.

Abstract
Stress has been suggested as one of important cause of human cancer without molecular biological evidence. Thus, we test the effect of stress-related hormones on cell viability and mitotic fidelity. Similarly to estrogen, stress hormone cortisol and its relative cortisone increase microtubule organizing center (MTOC) number through elevated expression of γ-tubulin and provide the Taxol resistance to human cancer cell lines. However, these effects are achieved by glucocorticoid hormone receptor (GR) but not by estrogen receptor (ER). Since ginsenosides possess steroid-like structure, we hypothesized that it would block the stress or estrogen-induced MTOC amplification and Taxol resistance. Among tested chemicals, rare ginsenoside, CSH1 (Rg6) shows obvious effect on inhibition of MTOC amplification, γ-tubulin induction and Taxol resistance. Comparing to Fulvestant (FST), ER-α specific inhibitor, this chemical can block the cortisol/cortisone-induced MTOC deregulation as well as ER-α signaling. Our results suggest that stress hormone induced tumorigenesis would be achieved by MTOC amplification, and CSH1 would be useful for prevention of stress-hormone or steroid hormone-induced chromosomal instability.

Abstract
Ginsenoside Rk1 (G-Rk1) is a unique component created by processing the ginseng plant (mainly Sung Ginseng (SG)) at high temperatures. The aim of our study was to systematically review the pharmacological effects of G-Rk1. We utilized and manually searched eight databases to select in vivo and in vitro original studies that provided information about biological, pharmaceutical effects of G-Rk1 and were published up to July 2017 with no restriction on language or study design. Out of the 156 papers identified, we retrieved 28 eligible papers in the first skimming phase of research. Several articles largely described the G-Rk1 anti-cancer activity investigating "cell viability", "cell proliferation inhibition", "apoptotic activity", and "effects of G-Rk1 on G1 phase and autophagy in tumor cells" either alone or in combination with G-Rg5. Others proved that it has antiplatelet aggregation activities, anti-inflammatory effects, anti-insulin resistance, nephroprotective effect, antimicrobial effect, cognitive function enhancement, lipid accumulation reduction and prevents osteoporosis. In conclusion, G-Rk1 has a significant anti-tumor effect on liver cancer, melanoma, lung cancer, cervical cancer, colon cancer, pancreatic cancer, gastric cancer, and breast adenocarcinoma against in vitro cell lines. In vivo experiments are further warranted to confirm these effects.

Abstract
This study was carried out to investigate the efficiency of red ginseng nanopowder in preventing collagen-induced arthritis (CIA) in mice. The mice were divided into five groups: normal group (no immunisation), control (CIA), powdered red ginseng (PRG), nanopowdered red ginseng (NRG) and methotrexate (MTX). Administering MTX, PRG and NRG to arthritic mice significantly decreased spleen indexes, clinical and histological scores compared to control group. Serum analysis of NRG and MTX groups showed a reduction in the cytokines such as the levels of tumour necrosis factor alpha (TNF-α), interleukin 6 (IL-6) and interleukin 1β (IL-1β) in comparison to PRG group. The levels of immunoglobulin M (IgM) and immunoglobulin G1 (IgG1) in the NRG group were significantly lower than those of the PRG group. In summary, the present study indicated that NRG can be effective in preventing type II collagen-induced rheumatoid arthritis in mice.

Abstract
Objectives. The adjuvant activity of Epimedium polysaccharide-propolis flavone liposome (EPL) was investigated in vitro and in vivo. Methods. In vitro, the effects of EPL at different concentrations on splenic lymphocytes proliferation and mRNA expression of IFN-γ and IL-6 were determined. In vivo, the adjuvant activities of EPL, EP, and mineral oil were compared in BALB/c mice through vaccination with inactivated porcine circovirus type 2 (PCV2) vaccine. Results. In vitro, EPL promoted lymphocytes proliferation and increased the mRNA expression of IFN-γ and IL-6, and the effect was significantly better than EP at all concentrations. In vivo, EPL significantly promoted the lymphocytes proliferation and the secretion of cytokines and improved the killing activity of NK cells, PCV2-specific antibody titers, and the proportion of T-cell subgroups. The effects of EPL were significantly better than EP and oil adjuvant at most time points. Conclusion. EPL could significantly improve both PCV2-specific cellular and humoral immune responses, and its medium dose had the best efficacy. Therefore, EPL would be exploited in an effective immune adjuvant for inactivated PCV2 vaccine.

Abstract
Compound K (CK), a highly active and bioavailable derivative obtained from protopanaxadiol ginsenosides, displays a wide variety of pharmacological properties, especially antitumor activity. However, the inadequacy of natural sources limits its application in the pharmaceutical industry. In this study, we firstly discovered that Cordyceps sinensis was a potent biocatalyst for the biotransformation of ginsenoside Rb1 into CK. After a series of investigations on the biotransformation parameters, an optimal composition of the biotransformation culture was found to be lactose, soybean powder and MgSO₄ without controlling the pH. Also, an optimum temperature of 30 °C for the biotransformation process was suggested in a range of 25 °C-50 °C. Then, a biotransformation pathway of Rb1→Rd→F2→CK was established using high performance liquid chromatography/quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF-MS). Our results demonstrated that the molar bioconversion rate of Rb1 to CK was more than 82% and the purity of CK produced by C. sinensis under the optimized conditions was more than 91%. In conclusion, the combination of C. sinensis and the optimized conditions is applicable for the industrial preparation of CK for medicinal purposes.

Abstract
Saponins, amphiphiles of natural origin with numerous biological activities, are widely used in the cosmetic and pharmaceutical industry. Some saponins exhibit relatively selective cytotoxic effects on cancer cells but the tendency of saponins to induce hemolysis limits their anticancer potential. This review focused on the effects of saponin activity on membranes and consequent implications for red blood and cancer cells. This activity seems to be strongly related to the amphiphilic character of saponins that gives them the ability to self-aggregate and interact with membrane components such as cholesterol and phospholipids. Membrane interactions of saponins with artificial membrane models, red blood and cancer cells are reviewed with respect to their molecular structures. The review considered the mechanisms of these membrane interactions and their consequences including the modulation of membrane dynamics, interaction with membrane rafts, and membrane lysis. We summarized current knowledge concerning the mechanisms involved in the interactions of saponins with membrane lipids and examined the structure activity relationship of saponins regarding hemolysis and cancer cell death. A critical analysis of these findings speculates on their potential to further develop new anticancer compounds.

Abstract
Background Ginsenoside F1, a pharmaceutical component of ginseng, is known to have antiaging, antioxidant, anticancer, and keratinocyte protective effects. However, the usage of ginsenoside F1 is restricted owing to the small amount found in Korean ginseng. Methods To enhance the production of ginsenoside F1 as a 10 g unit with high specificity, yield, and purity, an enzymatic bioconversion method was developed to adopt the commercial enzyme Cellulase KN from Aspergillus niger with food grade, which has ginsenoside-transforming ability. The proposed optimum reaction conditions of Cellulase KN were pH 5.0 and 50°C. Results Cellulase KN could effectively transform the ginsenosides Re and Rg1 into F1. A scaled-up biotransformation reaction was performed in a 10 L jar fermenter at pH 5.0 and 50°C for 48 h with protopanaxatriol-type ginsenoside mixture (at a concentration of 10 mg/mL) from ginseng roots. Finally, 13.0 g of F1 was produced from 50 g of protopanaxatriol-type ginsenoside mixture with 91.5 ± 1.1% chromatographic purity. Conclusion The results suggest that this enzymatic method could be exploited usefully for the preparation of ginsenoside F1 to be used in cosmetic, functional food, and pharmaceutical industries.

Abstract
Vaccination is one of the most effective and cost-benefit interventions that prevent the mortality and reduce morbidity from infectious pathogens. However, the licensed influenza vaccine induces strain-specific immunity and must be updated annually based on predicted strains that will circulate in the upcoming season. Influenza virus still causes significant health problems worldwide due to the low vaccine efficacy from unexpected outbreaks of next epidemic strains or the emergence of pandemic viruses. Current influenza vaccines are based on immunity to the hemagglutinin antigen that is highly variable among different influenza viruses circulating in humans and animals. Several scientific advances have been endeavored to develop universal vaccines that will induce broad protection. Universal vaccines have been focused on regions of viral proteins that are highly conserved across different virus subtypes. The strategies of universal vaccines include the matrix 2 protein, the hemagglutinin HA2 stalk domain, and T cell-based multivalent antigens. Supplemented and/or adjuvanted vaccination in combination with universal target antigenic vaccines would have much promise. This review summarizes encouraging scientific advances in the field with a focus on novel vaccine designs.

Abstract
Panax ginseng C.A. Meyer has been known as a valuable traditional Chinese medicines for thousands years of history. Ginsenosides, the main active constituents, exhibit prominent immunoregulation effect. The present study first describes a holistic method based on chemical characteristic and lymphocyte proliferative capacity to evaluate systematically the quality of P. ginseng in thirty samples from different seasons during 2-6 years. The HPLC fingerprints were evaluated using principle component analysis (PCA) and hierarchical clustering analysis (HCA). The spectrum-efficacy model between HPLC fingerprints and T-lymphocyte proliferative activities was investigated by principal component regression (PCR) and partial least squares (PLS). The results indicated that the growth of the ginsenosides could be grouped into three periods and from August of the fifth year, P. ginseng appeared significant lymphocyte proliferative capacity. Close correlation existed between the spectrum-efficacy relationship and ginsenosides Rb1, Ro, Rc, Rb2 and Re were the main contributive components to the lymphocyte proliferative capacity. This comprehensive strategy, providing reliable and adequate scientific evidence, could be applied to other TCMs to ameliorate their quality control.

Abstract
Thousands of literatures have described the diverse role of ginseng in physiological processes such as cancer, neurodegenerative disorders, insulin resistance, and hypertension. In particular, ginseng has been extensively reported to maintain homeostasis of the immune system and to enhance resistance to illness or microbial attacks through the regulation of immune system. Immune system comprises of different types of cells fulfilling their own specialized functions, and each type of the immune cells is differentially influenced and may be simultaneously controlled by ginseng treatment. This review summarizes the current knowledge on the effects of ginseng on immune system. We discuss how ginseng regulates each type of immune cells including macrophages, natural killer cells, dendritic cells, T cells, and B cells. We also describe how ginseng exhibits beneficial effects on controlling inflammatory diseases and microbial infections.

This study was conducted to evaluate the effects of natural bioactive products such as Manda enzyme (T1), Yangmyeongwon (T2), effective microorganisms (T3), and Kelpak (T4) on the growth and ginsenoside contents of Panax ginseng cultured in an aeroponic system using a two-layer vertical type of nutrient bath under natural light conditions. The growth of ginseng plants showed specific characteristics according to the positions in which they were cultured due to the difference of light transmittance and temperature in the upper and lower layers during aeroponic culture in a two-layer vertical type of system. The growth of the aerial part of the leaves and stems of ginseng plants cultured in the lower layer (4,000 to 6,000 lx, 23℃ to 26℃) of the nutrient bath was observed to be superior to that of the ginseng plants cultured in the upper layer (12,000 to 15,000 lx, 25℃ to 28℃). The leaf area was significantly larger in the treatment of T2 and T4 (46.70 cm2) than with other treatments. Conversely, the values of the root weight and root diameter were higher in ginseng plants cultured in the upper layer of the nutrient bath. The root weight was significantly heavier in the treatment of T4 (6.46 g) and T3 (6.26 g) than with other treatments. The total ginsenoside content in the leaves and roots was highest in the ginseng plants cultured by the treatment of T1, at 16.20%, while the total ginsenoside content obtained by other treatments decreased in the order of T4, T5 (control), T2, and T3, at 13.21%, 12.30%, 14.84%, and 14.86%, respectively. The total ginsenoside content of the ginseng leaves was found to be significantly higher in the treatment of T1 in the lower layer of the nutrient bath, at 15.30%, while the content of the ginseng roots in the treatments of T3 and T4, at 1.27% and 1.23%, respectively, was significantly higher than in other treatments in the upper layer of the nutrient bath.

Abstract
The ginsenoside-hydrolyzing β-glycosidase (Bgp3) derived from Microbacterium esteraromaticum transformed the major ginsenoside Rb2 to more pharmacologically active minor ginsenosides including compounds Y and K. The bgp3 gene consists of 2,271 bp encoding 756 amino acids which have homology to the glycosyl hydrolase family 3 protein domain. Bgp3 is capable of hydrolyzing beta-glucose links and arabinose links. HPLC analysis of the time course of ginsenoside Rb2 hydrolysis by Bgp3 (0.1 mg enzyme ml−1 in 20 mM sodium phosphate buffer at 40 °C and pH 7.0) showed that the glycosidase first hydrolyzed the inner glucose moiety attached to the C-3 position and then the arabinopyranose moiety attached to the C-20 position. Thus, Bgp3 hydrolyzed the ginsenoside Rb2 via the following pathway: Rb2 → compound Y → compound K.

Abstract
We used an aqueous leaf extract of Memecylon edule (Melastomataceae) to synthesize silver and gold nanoparticles. To our knowledge, this is the first report where M. edule leaf broth was found to be a suitable plant source for the green synthesis of silver and gold nanoparticles. On treatment of aqueous solutions of silver nitrate and chloroauric acid with M. edule leaf extract, stable silver and gold nanoparticles were rapidly formed. The gold nanoparticles were characterized by UV-visible spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDAX) and Fourier transform infra-red spectroscopy (FTIR). The kinetics of reduction of aqueous silver and gold ions during reaction with the M. edule leaf broth were easily analyzed by UV-visible spectroscopy. SEM analysis showed that aqueous gold ions, when exposed to M. edule leaf broth, were reduced and resulted in the biosynthesis of gold nanoparticles in the size range 20-50 nm. TEM analysis of gold nanoparticles showed formation of triangular, circular, and hexagonal shapes in the size range 10-45 nm. The resulting silver nanoparticles were predominantly square with uniform size range 50-90 nm. EDAX results confirmed the presence of triangular nanoparticles in the adsorption peak of 2.30 keV. Further FTIR analysis was also done to identify the functional groups in silver and gold nanoparticles. The characterized nanoparticles of M. edule have potential for various medical and industrial applications. Saponin presence in aqueous extract of M. edule is responsible for the mass production of silver and gold nanoparticles.

Abstract
Saponins are polar molecules that consist of a triterpene or steroid aglycone with one or more sugar chains. They are one of the most numerous and diverse groups of plant natural products. These molecules have important ecological and agronomic functions, contributing to pest and pathogen resistance and to food quality in crop plants. They also have a wide range of commercial applications in the food, cosmetics and pharmaceutical sectors. Although primarily found in plants, saponins are produced by certain other organisms, including starfish and sea cucumbers. The under explored biodiversity of this class of natural products is likely to prove to be a vital resource for discovery of high-value compounds. This review will focus on the biological activity of some of the best-studied examples of saponins, on the relationship between structure and function, and on prospects for synthesis of ‘‘designer’’ saponins.

Abstract
Florfenicol is a new type of broad-spectrum antibacterial that has been used in veterinary clinics. It showed immunosuppressive activity on the immune responses to vaccination against foot-and-mouth disease virus (FMDV) serotype O in mice. In the present study, BALB/c mice were immunized subcutaneously with FMDV serotype O antigen on days 1 and 14. Beginning on day 21, mice were treated with a single daily oral dose of florfenicol (50, 100, and 200 mg/kg) for seven consecutive days. On day 28, blood samples were collected to analyze FMDV-specific immunoglobulin G (IgG), IgG1, and IgG2b antibodies, and splenocytes were harvested to assess lymphocyte proliferation, CD3(+) T- and CD19(+) B-lymphocyte subsets. The results presented here demonstrated that florfenicol not only significantly suppressed concanavalin A-, lipopolysaccharide-induced splenocyte proliferation but also decreased the percentage of CD19(+) B-cells in a dose-dependent manner and suppressed CD3(+) T-cell at high doses. Moreover, FMDV-specific IgG, IgG1, and IgG2b antibody levels in FMDV-immunized mice were reduced by florfenicol. These results suggested that florfenicol could suppress humoral and cellular immune responses to vaccination against foot-and-mouth disease (FMD) in mice.
