Production Base & Quality Control

GreenVista operates a standardized production base in China with end-to-end quality control covering raw material sourcing, extraction, purification, testing, and packaging.

Production Capabilities

• Extraction technologies: solvent, water, ethanol, ultrasonic-assisted, supercritical CO2.
• Purification: macroporous resin chromatography, membrane separation, crystallization.
• Standardized active-ingredient processing: HPLC-controlled content levels.
• Packaging: 1 kg aluminum foil bags, 5 kg / 10 kg / 25 kg fiber drums, vacuum-sealed.
• Monthly output capacity aligned with bulk and custom-order requirements.

Quality Control Workflow

1. Incoming material inspection — raw herb identity, moisture, ash, microbial limits.
2. In-process testing — marker compound assays at extraction and purification stages.
3. Final batch testing — HPLC / GC / UV content + microbial + heavy metals + pesticides + residual solvents.
4. Third-party verification — SGS testing for representative batches per quarter.
5. Documented release — every batch ships with full COA, TDS, and SDS.

Equipment

HPLC, GC, UV-Vis spectrophotometer, atomic absorption spectroscopy (AAS), moisture analyzer, particle-size analyzer — typical QC instrumentation for standardized botanical extracts.
