What extraction method is used to produce this Epimedium dry extract?

The 10% Icariin dry extract uses a solvent extraction (ethanol/water) followed by concentration and spray drying to produce a standardized fine powder. It is a straightforward dry-extract process — no heavy purification is required at the 10% level.

Process Overview (10% Grade)

1. Raw material: dried Epimedium brevicornu leaf
2. Ethanol/water extraction under controlled temperature
3. Filtration and clarification
4. Vacuum concentration to a dense extract
5. Spray drying → fine powder
6. Standardization to Icariin ≥10% (HPLC)

For Higher Grades

• 30% / 50%: Add macroporous resin enrichment to concentrate icariin
• 98%: Further purification/crystallization for isolated icariin

No chemical solvents remain in the final powder — residual solvent is not detected (meets ICH Q3C). The 10% grade is the most economical and most commonly used for supplement manufacturing. Discuss specific solvent restrictions with our technical team.
