Abstract
The polysaccharides and triterpenes are important functional components of Ganoderma lucidum, but traditional preparation process of G. lucidum functional components can only realize the preparation of single functional component, which has poor targeting and low efficiency. In this study, the existence state of the functional components of G. lucidum was revealed. Then, the single step extraction process for functional components was established, and the precise structure evaluation of polysaccharide and triterpenes was conducted based on the process. The results showed that preparation time required for this strategy is only one-sixth of the traditional one, and 50 % of raw materials can be saved. Structural analysis of the functional components revealed that triterpenes were mainly Ganoderic acid and Lucidenic acid, and the polysaccharide structure was mainly 1,3-glucan and 1,3,6-glucan. The establishment of single step extraction strategy and the evaluation of the fine structure of functional components improved the efficiency of preparation and result determination, and provided an important basis for the development and utilization of green and low-carbon G. lucidum and even edible fungi resources and human nutritional dietary improvement strategies.

Ma Y, Zang R, Chen M, Zhang P, Cheng Y, Hu G. Study on fermentation preparation, physicochemical properties and biological activity of carboxymethylpachymaran with different degrees of substitution. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2024; 104:4234-4241. [PMID: 38294266 DOI: 10.1002/jsfa.13305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 11/09/2023] [Accepted: 01/12/2024] [Indexed: 02/01/2024]
Abstract
BACKGROUND Carboxymethylpachymaran (CMP) is created by carboxymethylating pachyman (PM), which increases its water solubility and enhances a number of biological activities. Traditional polysaccharides modified by carboxymethylation employ strong chemical techniques. Carboxymethylcellulose (CMC) has been used previously for liquid fermentation to carboxymethyl modify bacterial polysaccharides. This theory can be applied to fungal polysaccharides because Poria cocos has the ability to naturally utilize cellulose. RESULTS CMC with different degrees of substitution (DS) (0.7, 0.9 and 1.2) were added to P. cocos fermentation medium, and CMPs with different DS (0.38, 0.56 and 0.78, respectively) were prepared by liquid fermentation. The physical and chemical properties and biological activities of the CMPs were determined. Their structures were confirmed by Fourier transform infrared (FTIR) spectroscopy and monosaccharide composition. With the increase of DS, the viscosity and viscosity-average molecular weight of CMPs decreased, whereas polysaccharide content and water solubility increased, although the triple helix structure was not affected. The results of bioactivity assay showed that the higher the DS of CMPs, the higher the 2,2-diphenyl-1-picrylhydrazyl radical scavenging ability, and the stronger the bacterial inhibition ability. CONCLUSION The present study has developed a method for producing CMPs by P. cocos liquid fermentation. The results of the study confirm that enhancing the DS of CMP could effectively enhance its potential biological activity. The findings provide safe and reliable raw materials for creating CMP-related foods and encourage CMP application in the functional food industry. © 2024 Society of Chemical Industry.

The effect of sequential extraction on the physicochemical and rheological properties of Naematelia aurantialba polysaccharides. Int J Biol Macromol 2024; 265:130777. [PMID: 38479671 DOI: 10.1016/j.ijbiomac.2024.130777] [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: 10/11/2023] [Revised: 01/20/2024] [Accepted: 03/08/2024] [Indexed: 03/18/2024]
Abstract
To overcome the difficulty of separation and low rate of extraction caused by highly viscous polysaccharides from Naematelia aurantialba (NA), four N. aurantialba polysaccharides (NAPs) were sequentially extracted using water (enzyme-/ultrasound-assisted extraction), alkali (0.1 mol/L NaOH), and acid (0.1 mol/L HCl), and named E-NAP, U-NAP, Al-NAP, and Ac-NAP. The properties of four NAPs were different. The yields of NAPs were 26.05 % (Ac-NAP) > 20.33 % (Al-NAP) > 17.99 % (U-NAP) > 12.77 % (E-NAP), respectively. The monosaccharide composition of NAPs was composed primarily of mannose, xylose, glucose, glucuronic acid, and galactose. Sequential extraction improved the purity and solubility of NAPs, but decreased the particle size, thermal stability, water retention, and crystallinity. Two polysaccharides, U-NAP and Al-NAP, had a triple helix structure. All the NAPs were pseudoplastic fluids with concentration/frequency-dependent entangled structure. Al-NAP with the highest viscosity exhibited an elastic gel, while Ac-NAP with the lowest viscosity was a viscous gel. The behavior of NAPs differed from that predicted using the Cox-Merz rule, and in particular, E-NAP and U-NAP more significantly deviated from the rule. In this study, four NAPs with different properties were extracted sequentially, which provided a theoretical basis for the down-stream processing with high added-value and utilization of NA and NAP.

Abstract
Misgurnus anguillicaudatus, also known as oriental weather loach, is widely consumed and favored in East Asia due to its superior nutritional values and excellent flavor. In this study, a crude Misgurnus anguillicaudatus carbohydrates (MAC) was isolated from Misgurnus anguillicaudatus. Subsequently, two parts, which were named MAO and MAP, respectively, were separated from MAC, and their primary structures and immunomodulatory activity were investigated. The results showed that MAO had a molecular weight of 2854 Da, and principally consisted of arabinose (77.11%) and rhamnose (21.97%), together with minor levels of fucose (0.92%); MAP, with a molecular weight of 3873 Da, was mainly composed of fucose (87.55%) and a small amount of rhamnose (8.86%) and galactose (3.59%). The in vitro assay showed that MAC could significantly enhance the proliferation of macrophages without cytotoxicity and increase the production of immune substances (TNF-α, IL-6). Together with Western blot results, we speculated that MAC could stimulate RAW264.7 murine macrophage cells to secrete TNF-α and IL-6 through up-regulating TLR4-MAPK-p38 signaling pathways. The results indicated that MAC could be a potential immune agent and might provide meaningful information for further chain conformation and immune mechanism research.

Abstract
Tricholoma mongolicum Imai is an edible fungus rich in various health-promoting compounds, such as polysaccharides, polypeptides, polyunsaturated fatty acids, etc., and among them, polysaccharides have gotten more attention in recent research trends. This study explored the extraction of polysaccharides from T. mongolicum Imai by five extraction methods, including hot water extraction, ultrasound extraction, enzyme-assisted extraction, 0.1 M HCL extraction, and 0.1 M NaOH extraction. The effects of these extraction methods on the yield, chemical structure, apparent morphology, and the antioxidant activities of Tricholoma mongolicum Imai polysaccharides (TMIPs) were investigated in this study. The data showed that 0.1 M NaOH extraction produced the highest extraction yield compared to the other extraction methods. The results of high-performance gel permeation chromatography (HPGPC) and scanning electron microscopy (SEM) showed that different extraction methods had significant effects on the molecular weight and morphology of TMIPs. The results of Fourier transform infrared (FT-IR), X-ray diffraction (XRD), and thermogravimetric analysis showed that the extraction methods had no significant difference in functional groups, crystal structure, and thermal stability of TMIPs. The antioxidant activity of TMIPs extracted by ultrasound extraction was more prominent among the five polysaccharides, which might be related to a large number of low-molecular-weight components in molecular weight distribution.

Abstract
We herein report a food-derived polysaccharide (EJP) with the effect of relieving myocardial ischemia reperfusion injury (MIRI). This novel polysaccharide was isolated from the leaf of Eriobotrya japonica, and we first found its myocardium protective effects in vitro. Then, we firstly characterized EJP with a series of analytical technologies and further tested its effect on myocardial ischemia reperfusion injury (MIRI) with the illustration of the potential mechanisms in vivo. Interestingly, in the murine model of MIRI, administration of EJP effectively improved post-I/R heart contraction and limited the infarct size. Moreover, EJP significantly attenuated IR-induced oxidative damage and inflammatory reaction, as evidenced by decreasing MDA, IL-6, and TNF-α contents and increasing SOD activity and GSH-Px expression. In addition, we proved that EJP not only had no nephrotoxicity but also demonstrated a protective effect on the kidneys through HE staining and biochemical analysis. In sum, EJP, with a significant protective effect against myocardial I/R injury by showing anti-inflammatory and anti-oxidative activities, may become a meaningful drug candidate for the treatment of myocardial I/R injury.
