High-Purity Ergosterol Powder | Pharmaceutical Grade Fungal Extract | GMP-Certified Natural Sterol Supplier

Xi'an Jiayuan Bio-tech Co., Ltd., established in 2002 with RMB 30 million registered capital, specializes in producing pharmaceutical-grade Ergosterol Powder through advanced microbial fermentation technology. Our GMP standard, ISO9001 and HALAL certified manufacturing lines always produce high purity product at ≥98% or 99% requirements, supported by thorough HPLC testing. We manufacture several thousand kilos per year for pharmaceutical intermediates, cosmetic formulations and research uses across the world. 30 dedicated technical professionals with comprehensive regulatory paperwork including batch specific COAs to limit heavy metals (Pb ≤2ppm, As ≤2ppm) and 24 months stability under suitable storage circumstances.

What Is Ergosterol Powder?

The product is a premium fungal sterol isolated from yeast and ergot fungus cell walls. It is colourless acicular or flake crystals with chemical formula C28H44O. This vital membrane constituent is the immediate precursor for vitamin D2 production after UV irradiation.

Our product is manufactured at medicinal purity levels using controlled microbial fermentation techniques. The crystalline powder is very stable in storage and is appropriate for precise formulations that need constant quality while maintained in cold, dark settings.

This natural sterol, available in 90% and 95% standards, fulfils key industrial demands in pharmaceutical synthesis, dermatological research and specialised cosmetic applications.

Functions

The product has three important features that assist in overcoming unique formulation difficulties:

Performance of Pharmaceutical Intermediate: It is the direct biosynthetic precursor of vitamin D2 and steroid hormones , enabling economical manufacture of pharmaceuticals . Highly crystalline structure (≥98%) for reliable conversion rates in photochemical processes.

Bioactive Research Applications Laboratory investigations show substantial anti-inflammatory and antioxidant properties. Our controlled-purity material is used by investigators to study cellular membrane dynamics and fungal metabolic pathways with repeatable findings.

Functional Cosmetic Benefits: The molecular framework has great moisturising capabilities as well as a support of the processes of skin barrier restoration. In dermatological formulations, it improves the decrease of transepidermal water loss (TEWL) and stimulates cellular regeneration.

Application Fields

Pharmaceutical Synthesis

You can utilize our pharmaceutical-grade material as a critical starting compound for vitamin D2 production. The consistent ≥99% purity specification eliminates batch variation in downstream photochemical conversion processes.

Biotechnology Research

Research institutions rely on our traceable, COA-documented material for membrane biology studies and antifungal drug development. Each batch undergoes comprehensive heavy metal screening to prevent experimental interference.

Cosmetic Formulations

Our powder is used by cosmetic producers in high-end anti-ageing serums and barrier-repair creams. The amphiphilic nature of sterol helps in penetrating the stratum corneum and also maintains the formulation stability in pH ranges.

Nutraceutical Development

Your product development teams can leverage its antioxidant profile for specialized dietary supplements, subject to regional regulatory verification for novel ingredient status.
