Our 9-Step Plant Extraction Process
Every botanical batch undergoes controlled extraction, purification, and particle standardization.

1. Raw Materials
Botanicals sourced directly from origin, checked for species identity, moisture, and active marker content.

2. Extracting
Multi-stage water or ethanol extraction under controlled temperature and duration.

3. Concentration
Low-temperature vacuum evaporation to concentrate actives while preserving heat-sensitive bio-compounds.

4. Purification
Macroporous resin column chromatography and filtration to achieve targeted assay purity.

5. Drying & Spraying
Advanced spray-drying tower or vacuum drying for optimal moisture control and solubility.

6. Pulverizing
Precision milling to achieve smooth flowability and customer-defined particle sizes.

7. Sieving
Screening from 80 mesh up to 450 mesh superfine powder, with integrated metal detection.

8. Mixing
3D homogeneous powder blending to guarantee uniform active ratios across batch lots.

9. Finished Product
Final QC approval, pharmaceutical-grade drum packing, retained sampling, and COA release.
