Exploratory studies of the antidepressant effect of Cordyceps sinensis polysaccharide and its potential mechanism

Cordyceps sinensis, a traditionally prized medicinal fungus, contains polysaccharides as one of its main bioactive constituents, known for their significant immunomodulatory properties. In this study, we systematically investigated the composition and structure of Cordyceps sinensis polysaccharide, followed by an evaluation of its therapeutic effect on depression using a chronic restraint stress-induced depression model. The polysaccharide CSWP-2, extracted via hot water, precipitated with ethanol, and purified using DEAE-cellulose column chromatography from Cordyceps sinensis, is primarily composed of glucose, mannose, and galactose, with α-1,4-D-glucan as its major structural component. Behavioral tests, immunological profiling, metabolomics, and gut microbiota analyses indicated a notable ameliorative effect of CSWP-2 on depressive-like symptoms in mice.

A review on polysaccharide biosynthesis in Cordyceps militaris

Cordyceps militaris (C. militaris) is an edible parasitic fungus with medicinal properties. Its bioactive polysaccharides are structurally diverse and exhibit various metabolic and biological activities, including antitumor, hypoglycemic, antioxidant, hypolipidemic, anti-inflammatory, immunostimulatory, and anti-atherosclerotic effects. These properties make C. militaris-derived polysaccharides a promising candidate for future development. Recent advancements in microbial fermentation technology have enabled successful laboratory cultivation and extraction of these polysaccharides. These polysaccharides are structurally diverse and exhibit various biological activities, such as immunostimulatory, antioxidant, antitumor, hypolipidemic, and anti-atherosclerotic effects.

Apoptotic effect of cordycepin on A549 human lung cancer cell line

Cordycepin, an active ingredient in the insect fungus Cordyceps militaris, is in a category of compounds that exhibit significant therapeutic activity. The aim of the present study was to investigate the effect of cordycepin on cell proliferation, apoptosis, and cell cycle in A549 human lung cancer cells. MTT assay was used to evaluate the cytotoxic effect of cordycepin on A549 cell growth. Apoptotic effect was observed using cell morphology, DAPI staining, and DNA fragmentation studies.

Selective extraction of cordycepin from Cordyceps militaris – optimisation, kinetics and equilibrium studies

Cordycepin was separated successfully from Cordyceps militaris using extraction with a mixture of ethanol and water. Optimum temperature, composition of ethanol in water, solvent/solid ratio and pH of solvent were determined by a central composite design (CCD) with respect to extraction yield. The highest yield for cordycepin (96%) was predicted by the regression model and validated by comparison with the experimental results, showing good agreement.

Structure and hypoglycemic activity of a novel exopolysaccharide of Cordyceps militaris

A novel neutral exopolysaccharide (EPS-III) was isolated from culture broth of Cordyceps militaris (C. militaris). The EPS-III was a homogeneous polysaccharide with Mw of 1.56 x 10(3) kDa. The yield of EPS-III from culture broth was 123.2 +/- 3.1 mg/L and the sugar content was 93.32 +/- 0.87%. The backbone of EPS-III was mainly consisted of –>4)-alpha-D-Galp-(1–>, while –>3, 6)-alpha-D-Manp-(1–>, –>4)-alpha-D-Manp-(1–>, –>3)-beta-D-Galp-(1–> and –>3)-alpha-D-Glcp-(1–> were distributed in the backbone or in the branch chains. The EPS-III had helix structure when dissolved in weak alkaline solution. It also had branched and intertwined form on the surface. The inhibition of alpha-glucosidase significantly increased as the increase of purity of exopolysaccharides.

Isolation and Assessment of a Highly-Active Anti-Inflammatory Exopolysaccharide from Mycelial Fermentation of a Medicinal Fungus Cs-HK1

The purpose of this work was to fractionate the complex exopolysaccharide (EPS) from a medicinal fungus Ophiocordyceps sinensis Cs-HK1 based on the molecular weight (MW) range and to assess the in vitro anti-inflammatory activity of different EPS fractions in THP-1 cell culture. The lower MW fraction (EPS-LM-1) showed a much higher anti-inflammatory activity. EPS-LM-1 was identified as a heteropolysaccharide consisting of mannose, glucose, and galactose residues with an average MW of 360 kDa. EPS-LM-1 significantly inhibited the lipopolysaccharide-induced inflammatory responses with the effective concentrations for 50% inhibition below 5 microg/mL on a few major proinflammatory markers.

Cordycepin for Health and Wellbeing: A Potent Bioactive Metabolite of an Entomopathogenic Medicinal Fungus Cordyceps with Its Nutraceutical and Therapeutic Potential

Over the past few years, people have shown confidence and trust in naturally occurring food-based products such as nutraceuticals for the treatment or management of various chronic diseases. Medicinal mushrooms have been proved to be very effective against numerous serious ailments. Cordyceps, some of the most important medicinal mushrooms, have been in use in the traditional Chinese medicine system since a long time ago. They are considered an excellent reservoir of various bioactive components, of which cordycepin is believed to have the most nutraceutical potential. Based on several research reports, cordycepin indicates its nutraceutical values by showing possible therapeutic activity against various diseases by modulating a number of cellular signaling pathways due to its redox behavior.

Impact of different fermentation characteristics on the production of mycelial biomass, extra-cellular polysaccharides, intra-cellular polysaccharides, and on the antioxidant activities of Cordyceps militaris (L.) Fr. (strains AG-1, PSJ-1)

The mycelial biomass, antioxidant activity and production of extra- and intra-cellular polysaccharides production [EPS, IPS] of Cordyceps militaris strains AG-1, PSJ-1 were evaluated under different submerged liquid culture (SLC) conditions. At 24 0 C mycelial biomass and polysaccharide production of AG-1, PSJ-1 was optimal using PVC media and static culture conditions.

Immunological Investigation of Polysaccharides from Fermented Cordyceps Cs-4 in Healthy and Immunosuppressed Mice

Using fermented cordyceps powder Cs-4 as a substitute for natural cordyceps was benefit for life sciences. Therefore, it is of significance to investigate its main pharmacologically-active ingredients. In this work, fermented cordyceps polysaccharides with different molecular weights were isolated and purified. Various factors (i.e. extraction time, extraction power, and pH value) were investigated to obtain the response surface methodology values to most efficiently extract fermented cordyceps polysaccharides (FCP).

Enrichment of cordycepin for cosmeceutical applications: culture systems and strategies

Cordyceps spp. is the herbal medication initially used in China and has been reported as the unique resource of cordycepin. Cordycepin exhibits many health benefits, including anti-photoaging and anti-pigmentation; therefore, it potentially is a bioactive ingredient of cosmetic products. In order to enrich cordycepin content in Cordyceps, two artificial cultivation procedures, which are solid-state fermentation and liquid culture, were developed and optimized. The aim of this review is to illustrate cordycepin biosynthesis pathway in Cordyceps, and its bioactivity for cosmeceutical applications, as well as comparing the two different cultivation procedures.
