Iron deficiency anemia affects approximately 1.62 billion people worldwide,yet traditional iron supplements present bioavailability limitations and gastrointestinal side effects.This randomized,double-blind clinical trial investigated a novel Auricularia auricula polysaccharide-iron complex(AAPIC)compared with heme iron and ferrous glycinate in 180 iron-deficient adults receiving 30 mg elemental iron daily for 12 weeks.AAPIC achieved comparable hemoglobin improvements(from 98.3±8.7 to 126.5±9.2 g/L)to heme iron(from 97.8±9.1 to 128.3±8.6 g/L)and was significantly superior to ferrous glycinate(from 98.6±8.9 to 119.7±10.3 g/L;p<0.001).Iron absorption efficiency showed AAPIC at 23.7±4.2%,heme iron at 25.1±3.8%,and ferrous glycinate at 18.4±5.1%.Toxicological assessments revealed no hepatotoxicity,nephrotoxicity,or mutagenicity.Gastrointestinal adverse events occurred in 8.3%of AAPIC recipients versus 15.0%with ferrous glycinate and 10.0%with heme iron.The polysaccharide component facilitates iron transport through enhanced intestinal uptake mechanisms.AAPIC represents a promising,well-tolerated alternative with clinical efficacy comparable to established iron formulations. 展开更多

Auricularia auricula(AA)and Auricularia polytricha(AP)are popular edible fungi.This study successfully produced hypoglycemic polysaccharides from un-smashed or smashing and sieving(through a 10-mesh sieve)AA and AP(termed as AAP/AAP-10 and APP/APP-10)via scalable processes(water extraction,ethanolic precipitation and deproteinization).This is the first report to compare the effectiveness of AAP and APP in combating streptozotocin-induced oxidative stress and diabetes-related changes in mice(body weight,fasting blood glucose,serum insulin,proinflammatory mediator and cytokines,oxidative stress-related products,antioxidant enzymes).APP and AAP with different molecular weights and monosaccharide molar ratios could be therapeutic options for diabetes with a low dose(100 mg/kg/day)likely working better.At the same dose,APP generally performed more effective than AAP,and AAP-10/APP-10 seemed slightly more beneficial than AAP/APP.One mechanism underlying these antidiabetic functions might involve the NF-κB and associated signalling pathways.AP is cheaper than AA,thereby representing a favorable source of functional polysaccharides. 展开更多

The objective of the study was to examine the physicochemical properties and emulsification stability of three different Auricularia auricula polysaccharides(AAP)obtained through hot water extraction(AAP-W),hot acid extraction(AAP-A),and hot alkaline extraction(AAP-AL),respectively.The findings indicated that AAP-W exhibited superior emulsification stability compared to the other two polysaccharides.AAP-W was employed as a natural emulsifier for emulsion preparation,to examine the influence of varying polysaccharide concentrations and oil-water ratios on emulsion stability.Additionally,an investigation was conducted into the stability of the emulsions with respect to pH and salt ion concentration.The findings revealed that the most favorable polysaccharide concentration for the AAP-W emulsion was determined to be 1%,while the volume fraction of the oil phase was established at 0.5.It was also observed that the emulsion exhibited robust stability even in challenging conditions characterized by strong acidic(pH 3−5)or basic environments(pH 9−11),as well as high concentrations of salt ions(0−500 mM).Furthermore,the construction of an AAP-W emulsion system incorporatingβ-carotene was undertaken to enhance the preservation,bioavailability,and digestive stability ofβ-carotene,thereby expanding the potential applications of Auricularia auricula polysaccharides.This endeavor also presents a novel approach towards the advancement of novel functional food products. 展开更多

Conventional mechanical method and mechanical method combined with vacuum freeze-drying technology were used to make the ultra-fine powders of edible fungus (Auricularia auricular). The content of basic nutrients, amino acid, micro structure and their properties of raw edible fungus and the edible fungus powders obtained with the two methods were analyzed and compared. The granularity size and micro-structure of the pulverized samples were analyzed by SEM and TEM technology. The average granularity size of the edible fungus powder obtained with mechanical method was 1–5 μm, while that obtained with mechanical method combined with vacuum freeze-drying process was 0.5–1 μm. The ultra-fine powders of edible fungus obtained with the two methods had better water recovery capability and quality, and their preserving time was longer than that of raw edible fungus. All the properties of the ultra-fine powders of edible fungus obtained with the vacuum freeze-drying technology were evidently superior to that of the conventional mechanical method.

In order to improve the anticoagulant function of Auricularia auricula, Auricularia auricula polysaccharide （AAP） was converted into its derivatives by the microbial fermentation method and then polysaccharide derivatives with stronger anticoagulant activity were prepared. The optimal conditions for fermenting the polysaccharide from A. auricula were examined and the in vitro anticoagulant activities of transformed and untransformed polysaccharides were compared. Response surface tests and an orthogonal experiment indicated that the best conditions for microbial conversion of AAP3 were an AAP3 concentration of 4.0 mg/ mL, a ratio of substrate （AAP3 ） to donor （p-hydroxybenzoic acid） of 40：1, and a pH of 6.0. Bacillus subtilis Bs-07 was inoculated and then placed on a rotary shaker （ 120 r/min）, followed by fermentation for 48 h at 35 ℃. The conversion rate was found to be greater than 40%. The result of in vitro anticoagulant activity showed that the transformed polysaccharide improved activated partial thromboplastin time, prothrombin time, and thrombin time values and greatly enhanced anticoagulant activity compared to the untransformed polysaccharide. 展开更多

We aimed to investigate the synergistic effects of ultrasonic waves and repeated freeze-thaw cycles on cel-wal destruction of Auricularia auric-ula mycelia, and determine the best combination of conditions for cel-wal destruc-tion of Auricularia auricula mycelia. [Method] The effects of destruction time, added water, destruction times, freeze time and number of freeze-thaw cycles during ultra-sonic treatment on polysaccharide yield were investigated by single-factor test in our research. The optimum conditions for cel-wal destruction of Auricularia auricula mycelia by the synergistic effect of ultrasonic waves and repeated freeze-thaw cycles were ascertained by orthogonal test. [Result] The results of single test indicated the best combination of conditions was as fol ows： freeze time, 30 min; destruction time, 20 min; added water, 15 times; destruction times, 2 times; number of freeze-thaw cycles, 3 cycles. The results of orthogonal test indicated the influencing factors ranked as destruction time 〉 destruction times 〉 freeze time. The best combination of conditions was as fol ows： freeze time, 30 min; destruction time, 25 min; destruc-tion times, 2 times. Under above conditions, the polysaccharide yield reached 57.76 mg/g. [Conclusion] This research would provide a basis and reference for practical production. 展开更多

The functional formula diet AHP, containing polysaccharides from Auricularia auricular, polyphenolic compounds from Hawthorn (Crataegus) and Pueraria radix, has been recently developed as a dietary intervention against dyslipidemia in our previous study. In the present study, its antioxidant activities and protective effects against proliferation of vascular smooth muscle cells (VSMCs) were investigated. AHP possessed the potent radical-scavenging effects against hydroxyl and superoxide radicals, and also the inhibitory effects against peroxidation of low density lipoprotein induced by Cu2+ in vitro. The protective effects of AHP against proliferation of VSMCs were evaluated through the methodology of serum pharmacology. The serum containing AHP significantly inhibited the proliferation of VSMCs induced by oxidized low density lipoprotein in a time- and dose-dependent manner, and also promoted the nitric oxide production of VSMCs. Our study indicated that this functional formula diet would be a potent alternative as a functional diet to prevent atherosclerosis at early stage. 展开更多

This study explored the therapeutic effects of Auricularia auricula melanin(AAM)on alcoholic liver damage in vitro and in vivo.Human normal liver L02 cells were pre-treated with ethanol and then treated with AAM to explore the therapeutic effect of AAM on ethanol-induced hepatocyte injury.The results show that AAM signifi cantly elevated the cell viability,ameliorated the cell morphology,reduced the ROS and increased the GSH/GSSG of ethanol-pretreated L02 cells.Then,mice were administered with ethanol to induce acute alcoholic liver damage,and administered with AAM to further study the therapeutic effect of AAM on alcoholic liver damage in mice.As a result,AAM reduced the levels of ALT,AST,TG,and MDA,increased the levels of ADH,SOD,and CAT in liver damage mice.The therapeutic effect of AAM may be related to inhibition of CYP2E1 expression and activation of Nrf2 and its downstream antioxidase.The research enriched the bioactivity of AAM and provided some ideas for the development of melanin-related health foods. 展开更多

We examined the rheological and gel properties of Auricularia auricula pulp solution and konjac glucomannan solution at different concentrations(1.2,2.4,3.6,4.8,and 6.0 g/100 mL)as well as A.auricula pulp/konjac glucomannan compound system at different mass ratios(4.8:1.2,3.6:2.4,2.4:3.6,and 1.2:4.8)and discussed the interaction mechanism.The results showed that the apparent viscosity,dynamic viscoelasticity,energy storage modulus(G’),and loss modulus(G”)of the compound system increased with the increase of A.auricula pulp mass ratio.The thixotropic ring decreased with the increase of A.auricula pulp mass ratio,indicating that A.auricula pulp could improve the thixotropy of the compound system.The results of the texture analysis and water retention test showed that konjac glucomannan was the decisive factor for the strength and hardness of A.auricula pulp/konjac glucomannan compound gel,and A.auricula pulp could significantly improve the elasticity,viscosity,and water-holding capacity of the compound system.based on Fourier transform infrared(FTir)spectroscopy and cryo-scanning electron microscopy(cryo-SEM)analyses,we preliminarily concluded that an interaction occurred between A.auricula pulp and konjac glucomannan in the compound system,and a gel network structure was formed. 展开更多

Auricularia auricula polysaccharides(AHP)have potential immunomodulatory activities.However,the relationship between polysaccharides,intestinal microbiota,and immune activity remains unclear.Therefore,to explore this relationship,we performed immunosuppressive donor,fecal microbiota transplantation(FMT),and pseudo-sterile mouse validation experiments.Our results showed that AHP enhanced immunomodulatory activity,as evidenced by the alleviation of cyclophosphamide(Cy)-induced body weight loss,spleen and thymus atrophy,and splenic and colonic lesions.Additionally,AHP effectively regulated antioxidant enzyme activities(SOD,T-AOC,CAT,GSH-Px),lipid peroxidation product content(MDA),levels of immune factors(TNF-α,IFN-γ,IL-2,IL-4,IL-6),immunoglobulins(sIgA),and the expression of tight junction proteins(Muc2,ZO-1,Occuldin,and Claudin-1)in the colon of immunosuppressed mice.FMT results demonstrated that FAHP displayed superior immunomodulatory ability and could further affect the abundance of Dehydroepiandrosterone,Prostaglandin E2,Cholesterol and Pregnenolone by increasing the abundance of unclassified_Muribaculaceae,Desulfovibrio,Alloprevotella,and unclassified_Oscillospiraceae and decreasing that of Staphylococcus,Bacteroides,and Corynebacterium.Pseudo-sterilization experiments showed that AHP was unable to increase antioxidant enzyme activity,reduce lipid peroxidation content,or promote the release of immune factors.In brief,AHP did not alleviate Cy-induced immunosuppression after microbiota elimination.In summary,AHP exerted a protective effect against Cy-induced immunosuppression and intestinal damage by modulating intestinal microbiota and its metabolites.These findings provide new insights into the mechanisms by which AHP,as a functional food or drug,promotes immune response regulation and maintains intestinal health. 展开更多

In this paper,using to the comprehensive scoring method,pressure shear assisted extraction was used to prepare polysaccharide from Auricularia auricula(PS-AAP)by orthogonal test to optimize the extraction.The highest comprehensive score(90.70)was obtained under 1:70 g/mL solid-liquid ratio,110°C reaction temperature,60 min reaction time and 1.0 MPa reaction pressure.Compared to AAP by water bath(WB-AAP),PS-AAP led to a higher extraction efficiency and decreased the relative molecular weight.In addition,infrared spectrum(FT-IR)analysis showed that pressure shear assisted did not change the polysaccharide structure.Scanning electron microscope(SEM)showed that PS-AAP was smaller and more broken by pressure shear assisted.Furthermore,the ratio of glucose to mannose in PS-AAP was relatively higher than WB-AAP,which also proved that PS-AAP had certain antioxidant and hypoglycemic activities.Compared with WB-AAP,the inhibitionα-glucosidase andα-amylase activity of PS-AAP increased by 11.37%and 24.43%respectively.These results revealed that PS-AAP has the poten-tial value of being a antioxidant and hypoglycemic agent. 展开更多
