Source & Traceability
Choice of Raw Material
We gather just the aerial parts (stems and leaves) of Epimedium brevicornum during the peak blooming season when the concentration of icariin is at optimum levels. Our sourcing partners include growing facilities in Shaanxi, Gansu, and Sichuan, all of which are known for producing high quality Epimedium.
Grade Classification
· Dietary Grade: Carefully tested for impurities young leaves from blooming plants for 10%-20% standardized goods
· Organic Grade: USDA & ECOCERT certified, grown without synthetic pesticides or fertilizers, processed on specialized production lines
· Common Grade: Mixed leaves after harvest, economical for 5:1 ratio extracts
Supply Chain Transparency
Each batch has origin traceability paperwork and Certificate of Analysis (COA). Organic batches come with full certification packages from soil to extract to prove compliance.
Solubility & Stability Profile
Solubility Characteristics
· Ethanol (70-95%): Highly soluble
· Propylene Glycol: Good solubility
· Hot Water – Moderately soluble
· Cold water: Sparingly soluble
· Oils: Insoluble (needs emulsifiers for oil-based compositions)
Stability Parameters
· Thermal Stability Stable to 80°C, Prolonged exposure >90°C leads to glycoside hydrolysis
· pH Stability: Optimal pH 4.0-7.0; declines in extremely acidic or alkaline circumstances
· Light Sensitive Dry Epimedium Extract Powder Light sensitive. Store in Amber bottles for aqueous solutions
· Storage Recommendations: Store sealed in cold, dark, dry circumstances; shelf life 24 months
Manufacturing Process
2. Pretreatment：Low-temperature drying (40-50°C); coarse grinding to 10-20 mesh Preserve flavonoid integrity
3. Extraction ：Triple ethanol reflux (70% ethanol, 70-75°C) Solvent ratio 1:10, three cycles
4. Concentration ：Vacuum evaporation at 55-65°C; ethanol recovery Density 1.15-1.20 at 60°C
5. Alcohol Precipitation ：Add 95% ethanol to 70%; settle 24h at 4°C Remove polysaccharides and proteins
6. Resin Purification：AB-8 macroporous resin column; gradient elution Differentiate 10%/20% specifications
7. Drying：Spray drying (inlet 160°C, outlet 80°C) Final moisture <5%
8. Milling & Packaging ：Pulverize to target mesh; blend and pack in PE bags + drums Uniform particle distribution
Key Differentiators:
· 5% specification skip resin purification to save cost
· 20% products multi-stage resin + recrystallization for pharma grade purity

Frequently Asked Questions (FAQ)
Q1: What's the difference between 10% and 20% icariin content?
A: 10% is purified in one step with resin. Good for dietary supplements. 20% employs multi-stage refining and recrystallization for pharmaceutical grade purity in premium formulations.
Q2: Can you supply organic-certified batches with full documentation?
A: Yes. Our organic product is USDA/ECOCERT certified and fully traceable from certified farmers to final product.
Q3: Is the extract suitable for oil-based creams?
A: It does not dissolve in oils. Emulsifiers such as polysorbate or propylene glycol are used for optimal dispersion for cosmetic purposes.
Q4: What's your minimum order quantity and lead time?
A: MOQ is 25kgs. Stock goods lead time 10-15 days, bespoke specifications lead time 20-30 days. Free samples are available.
Q5: How do you ensure batch-to-batch consistency?
A: Do you combine the production batches? A: Yes, in a 3-D mixer, then test each batch before release. Statistical process control keeps the coefficient of variation within 5%.
