Stigmasterol Powder

Premium Stigmasterol Powder 90%-95% – High-Purity Phytosterol Extract for Pharma, Nutraceutical & Feed Applications

Xi'an Jiayuan Bio-tech delivers pharmaceutical-grade Stigmasterol Powder extracted from Glycine max (L.) Merr (soybean) seeds, achieving up to 95% purity through advanced solvent crystallization technology. With over 20 years of manufacturing excellence since our founding in 2002, we operate two GMP-standard production lines with annual output reaching several hundred tons. With the registered capital of RMB30 million and 30 technical specialists, we strictly regulate quality from the purchase of raw materials to the final testing. HPLC and GC-MS verification for each batch. Heavy metal limitations are maintained (Pb ≤1ppm, As ≤1ppm) and moisture content ≤5% with ISO9001, HALAL and KOSHER certifications.

What Is Stigmasterol Powder?

The product is a high-value plant sterol from the phytosterol family (Molecular formula: C29H48O, CAS: 83-48-7). It’s a white crystalline powder that solves three big problems in the business. Firstly, it is an important pharmacological intermediary for the synthesis of progesterone and vitamin D3, bypassing the need for animal sources. Second, it has cholesterol control solutions for functional foods, providing clean-label alternatives to synthetic ingredients. Third, it is used as a feed addition for improving the nutrition of cattle and so boosting animal health in a natural way.

Our patented crystallization technique purifies to 90%-95% from soybean oil distillates that include ~29% phytosterols. This concentration provides optimal efficiency in downstream applications with excellent stability.

Core Functions

Cholesterol Regulation: Clinical trials show that stigmasterol competes with cholesterol for intestinal absorption. It has been shown to reduce LDL levels by 8-15% in food products enriched with 1.5-2g daily dosages.

Anti-inflammatory activity: The chemical inhibits COX-2 and NF-κB pathways, allowing its use in nutraceutical formulations aimed at chronic inflammation.

Antioxidant Protection It has shown hydroxyl radical scavenging activity and protects cellular frameworks from oxidative stress, improving product shelf life in food matrices.

Pharmaceutical Synthesis: It is a precursor for steroidal hormones, allowing the cost-effective manufacture of progesterone and vitamin D3, eliminating the need for animal-derived cholesterol.

Application Areas

Pharmaceutical Industry Your R&D teams may use our 95% purity grade as a direct precursor in hormone manufacturing routes. It decreases the manufacturing cost by 20-30% compared to cholesterol based approaches.

Functional Foods: Stigmasterol is formulated into cholesterol-lowering margarines, dairy substitutes and supplement mixes. Its neutral taste and thermal stability (up to 180°C) allow easy incorporation into production.

Animal Nutrition: Used by livestock feed makers at concentrations of 200-500ppm to boost lipid metabolism and immunological response in poultry and pigs, hence improving growth performance without resorting to the use of synthetic chemicals.

Cosmetic Use: The emollient characteristics may be used in anti-aging creams and serums to help maintain lipid barriers and improve skin suppleness.

Quality Control

First, we check suppliers of soybean oil distillates in our quality assurance system. Critical control points are monitored throughout extraction, crystallization (with exact temperature gradients) and drying to ensure that solvent residues are minimized to below 10ppm.

Finished batches are tested in triplicate for HPLC confirming stigmasterol content ≥90%/95%, GC-MS for pesticide residues (<0.05ppm) and microbiological tests for total plate count <1000CFU/g. Each shipment is accompanied with batch specific Certificates of Analysis (COA) for 17 quality factors. Our traceability system tracks Stigmasterol Powder from raw material lot numbers through customer delivery, ensuring full compliance with EU Novel Food Regulations and China's food additive licensing requirements.
