1. How Do We Solve Your Quality Inconsistency Problem?

Unpredictable raw materials lead to costly batch failures and compromised finished product efficacy. We place rigorous, validated analytics at the core of our production. We use High-Performance Liquid Chromatography (HPLC) as our primary method to guarantee ≥98% purity of Dioscin in every batch. Furthermore, we test for related saponins (such as protodioscin and methylprotodioscin), heavy metals (lead, arsenic, cadmium), residual solvents, and microbial contaminants. Each shipment includes a comprehensive Certificate of Analysis (CoA) . Consequently, you can streamline your incoming quality control and launch products with total confidence.

2. What Is It, and Why Is Our Sourcing & Extraction Superior?

Dioscin is a steroidal saponin found naturally in various Dioscorea species, including Dioscorea nipponica and Dioscorea zingiberensis. It is composed of a steroidal aglycone linked to a sugar chain (a trisaccharide), which contributes to its amphiphilic properties. This compound is prized for its ability to modulate inflammatory pathways, support cardiovascular health, and exhibit potential anticancer activity.

We source our Dioscin from certified, sustainably harvested Dioscorea rhizomes. We use a proprietary, eco-friendly extraction process involving ethanol-water extraction followed by advanced chromatographic purification. Unlike suppliers who rely on crude solvent extraction, our process ensures a white to off-white crystalline powder with a purity that meets the strictest requirements.

3. Matching the Right Grade to Your Product Line

Your product portfolio is diverse. Your ingredient should be versatile. We offer Dioscin 98% in targeted grades to match your specific formulation needs:

• Pharmaceutical Research Grade: Ideal for drug development, preclinical studies, and formulation research. Subjected to additional testing for residual solvents and impurities.

• Nutraceutical Grade: Designed for dietary supplements targeting joint health, cardiovascular support, and anti-inflammatory benefits. Meets cGMP standards for oral consumption.

• Cosmetic Grade: Suitable for anti-aging serums, creams, and lotions where purity and stability are critical for skin safety.

Tell us your application and target market. We will direct you to the most cost-effective and technically suitable grade.

4. Solving Your Formulation & Solubility Problems

A common complaint about Dioscin is its poor water solubility, which limits its use in aqueous systems. Our Dioscin 98% solves this by offering a crystalline form that is soluble in ethanol, DMSO, and organic solvents. For aqueous formulations, we recommend using it with a compatible surfactant or liposomal delivery system. The white to off-white powder has a clean, neutral odor. At typical use levels, it delivers significant benefits without impacting product texture or stability.

5. Eliminate Inventory Waste with Proper Storage Guidelines

A hidden operational cost is ingredient degradation in the warehouse. Our Dioscin 98% is stable when stored correctly. First, keep it in a cool, dry place (2-8°C / 36-46°F) away from direct sunlight and moisture. Next, use tightly sealed, airtight containers to prevent oxidation. For long-term storage, freezing at -20°C is recommended. Under these conditions, the powder maintains its full potency for 24 months from the date of manufacture. Avoid repeated freeze-thaw cycles. This extended shelf life allows you to purchase in cost-effective bulk quantities without fear of degradation.
