Grifolan (CAS 9051-97-2) is a branched beta-1,3/1,6-glucan isolated from the fruiting body of Grifola frondosa, the mushroom known as Maitake. Our product is manufactured through hot water extraction, alcohol precipitation, and subsequent purification to yield a polysaccharide fraction with a beta-glucan content of ≥70%. The material is presented as a free-flowing, off-white powder, standardized for consistent biological activity and suitable for use in functional food, dietary supplement, and cosmetic applications.
With a molecular weight typically in the range of 500–1000 kDa, Grifolan exhibits well-documented immunomodulatory properties, primarily through activation of macrophages and dendritic cells via dectin-1 and TLR-2/4 signaling pathways. This makes it a valuable ingredient in products targeting immune support, gut health, and overall wellness. Our production process ensures batch-to-batch reproducibility, with each batch subjected to rigorous quality control.
Synonyms: Grifolan, Grifola frondosa polysaccharide, Maitake beta-glucan, Beta-1,3/1,6-glucan from Grifola frondosa, GF-1, Maitake extract polysaccharide
Every batch is tested for beta-glucan content (enzymatic assay), loss on drying, heavy metals, and microbial limits. We provide a complete COA, MSDS, and TDS with each shipment. Stability data under accelerated and long-term conditions are available for qualification purposes.
Standard packaging is 1 kg, 5 kg, and 25 kg in sealed aluminum foil bags, with custom sizes available upon request. In-stock items ship within 3–5 business days. MOQ is 1 kg. For pricing, samples, and bulk orders, contact our sales team.
