Quality in botanical extracts is not simply a matter of potency—it encompasses purity, safety, consistency, and traceability. At Nourel, every batch undergoes a rigorous series of tests before leaving our facility.

Key Quality Indicators

1. Active Compound Concentration

The most fundamental quality marker is the concentration of target active compounds. Standardized extracts guarantee a consistent level of key bioactive molecules across every batch.

2. Heavy Metal Testing

Plants can accumulate heavy metals from soil and water. Our extracts are tested against international limits for lead, cadmium, arsenic, and mercury to ensure safety.

3. Microbiological Purity

Total microbial count, yeast, mould, and absence of specific pathogens (Salmonella, E. coli) are verified in every production run.

4. Solvent Residues

Residual solvents from extraction are tested to comply with ICH Q3C limits, safeguarding consumer health.
