Golden Oyster Mushroom Pleurotus Citrinopileatus Extract Powder

Pleurotus citrinopileatus (Golden Oyster Mushroom) Extract is rich in ergothioneine, alongside natural active components including Pleurotus citrinopileatus polysaccharides, polyphenols and various amino acids. It helps scavenge free radicals, delivers antioxidant and soothing anti-inflammatory effects, supports mitochondrial protection and reduces photoaging. It also contributes to maintaining cognitive, ocular and cardiovascular health.

This raw material is widely used in two major sectors. For oral applications, it can be incorporated into dietary supplements and functional powdered drinks, focusing on cellular anti-aging, brain health and immune support. For skincare, it serves as a natural active ingredient in serums, creams and sunscreen formulations to repair the skin barrier, even out skin tone and mitigate dullness. It is a highly sought-after natural mushroom-derived raw material for health food and cosmetic industries.

Healthkintai^® has been engaged in the R&D and production of plant extracts for over a decade, with profound industry experience and mature, stable production processes and quality control systems. We provide consistent supply of cosmetic active ingredients and raw materials for dietary supplements. Our Pleurotus citrinopileatus extract powder is sourced from natural mushrooms with no extra additives, retaining abundant active substances such as ergothioneine. With reliable quality, we support sample testing and bulk orders. Feel free to contact us at health@kintaibio.com for inquiries and discussions.

In the USA

In the United States, the regulatory status of Pleurotus citrinopileatus is generally permissive. The core basis is that it is classified as Generally Recognized As Safe (GRAS) by the U.S. Food and Drug Administration (FDA), and it does not produce major mycotoxins such as aflatoxins, ochratoxin A or fumonisins under normal substrate conditions. Therefore, extracts derived from its fruiting bodies can generally be directly marketed as dietary supplement ingredients without pre-market approval from the FDA.

In the EU

Pleurotus citrinopileatus has a long history of consumption in Europe, so extracts sourced from its fruiting bodies are generally not regarded as Novel Food and may be used without pre-market authorisation from the European Food Safety Authority (EFSA). Fruiting bodies of Pleurotus spp. are explicitly categorised as "non-Novel Food".

If ergothioneine is adopted as the standardisation marker or core selling point of the product, the independent regulatory status of this ingredient requires separate attention: the EU authorised L-ergothioneine as a Novel Food ingredient in 2017 and later expanded its scope of use, with specific rules governing its maximum usage levels, permitted food categories and target population groups.

Antioxidant Pleurotus Citrinopileatus Extract

The antioxidant properties of Pleurotus citrinopileatus stem from its abundant bioactive compounds, with ergothioneine and fungal polysaccharides serving as the primary active ingredients. Ergothioneine efficiently scavenges free radicals, exhibiting strong activity against hydroxyl radicals, DPPH radicals and ABTS⁺ radicals, and delivers excellent oxygen radical absorbance capacity (ORAC).

 

Pleurotus citrinopileatus polysaccharides help elevate the levels of superoxide dismutase, catalase and glutathione peroxidase in tissues including the liver, heart and kidney, while reducing the production of malondialdehyde, a lipid peroxidation product, to mitigate oxidative tissue damage. In addition, phenolic compounds present in the fruiting bodies, such as gallic acid, chlorogenic acid and ferulic acid, exert reducing effects and chelate ferrous ions to provide synergistic antioxidant support.

Anti-obesity Pleurotus Citrinopileatus Extract

Pleurotus citrinopileatus extract contains natural active components including ergothioneine and polysaccharides, which support healthy glucose and lipid metabolism through multiple pathways. Ergothioneine helps inhibit pancreatic lipase activity and reduces the intestinal absorption of dietary fats. Polysaccharides of different molecular weights from Pleurotus citrinopileatus can suppress adipocyte proliferation and improve leptin and insulin sensitivity, among which the high-molecular-weight polysaccharide PCP40 exhibits stronger lipid-lowering potential.

 

Animal studies demonstrate that aqueous and alcoholic extracts of Pleurotus citrinopileatus help maintain healthy body weight and normal visceral fat levels, support serum triglycerides, total cholesterol, low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) within normal ranges, preserve glucose tolerance and promote liver and kidney health. Its polysaccharide fractions also boost the production of intestinal short-chain fatty acids, increase the abundance of beneficial microbiota, restore intestinal homeostasis, alleviate low-grade chronic inflammation, and regulate lipid metabolism via the gut-liver axis.

Boosting Immunity Pleurotus Citrinopileatus Extract

Pleurotus citrinopileatus extract contains pleurotus citrinopileatus polysaccharides (mainly β-glucan) and glycoprotein complexes, which help support the health of human innate and adaptive immunity. These ingredients act on Dectin-1 and TLR receptors on dendritic cells and macrophages, assist in boosting the activity of macrophages and NK cells, support normal lymphocyte proliferation, and modulate the levels of cytokines such as IL-2, IFN-γ and TNF-α to maintain the health of immune organs including the spleen and thymus.

 

Phenolic compounds and ergothioneine in the extract help scavenge free radicals, reduce the impact of oxidative stress on immune cells, and exert beneficial effects on gut-associated immune tissues to maintain immune homeostasis in the body, support the body's natural defense, and are suitable for daily immune health support.

 

Pleurotus Citrinopileatus Extract in Functional Foods

As an edible and medicinal homologous mushroom raw material, Pleurotus citrinopileatus extract (also known as Golden Oyster Mushroom extract) is widely applied in solid beverages, compressed candy, meal replacement powders, compound mushroom soup bases, baked snacks and other products. Its core active components include Pleurotus citrinopileatus polysaccharides, ergothioneine and a variety of essential amino acids. It can serve as a flavor ingredient to endow products with a natural umami mushroom taste and pale golden color, and also be incorporated as a functional ingredient.

Golden Oyster Mushroom Extract in Dietary Supplements

Golden oyster mushroom extract is mainly formulated in standardized polysaccharide or ergothioneine-enriched grades. Pleurotus citrinopileatus polysaccharides modulate immune cell activity and support lipid metabolism. Ergothioneine features a unique cellular transport mechanism, enabling it to cross the blood-brain barrier and scavenge mitochondrial free radicals. In dietary supplements, it is often used alone or blended with other mushroom extracts such as reishi and lion's mane, manufactured into capsules, powders and oral liquids for brain health, cardiovascular support and anti-fatigue dietary supplement products.

Golden Oyster Mushroom Extract in Skincare Products

Pleurotus citrinopileatus extract (ergothioneine + polysaccharides) acts as a natural skincare active ingredient, applied in serums, toners, lotions, creams and eye care products. It is formulated for anti-photoaging, soothing and brightening benefits. The typical recommended addition level in the industry is ≤2%. Available forms include aqueous extracts and spray-dried powders. This ingredient offers good formulation compatibility, resistance to light and temperature fluctuations, and is suitable for sensitive skin formulations.

KINTAI Pleurotus Citrinopileatus Extract is extracted from carefully selected fruiting bodies of Pleurotus citrinopileatus. Our best-selling standard specification contains 1% Ergothioneine. Adopting low-temperature extraction technology without harmful organic solvents, this gentle extraction environment effectively stabilizes the molecular structure of ergothioneine, preserves its natural activity and minimizes the loss of active components.

The entire production process complies with GMP guidelines. We hold complete export qualifications to meet compliance requirements for overseas customers. Full documentation including COA and MSDS can be supplied upon shipment.
