How do you ensure batch-to-batch consistency of Chuanxiong rhizome oil?
Consistency is controlled by standardized raw material, fixed process parameters, and multi-point QC on every batch.
Consistency Controls
| Control | Method |
|---|---|
| Raw material | Dao-di rhizome sourcing, moisture and marker pre-screening |
| GC-MS fingerprint | ISO 11024 method; profile similarity ≥90% vs. reference |
| HPLC markers | Ligustilide and ferulic acid quantified on every batch |
| Physical tests | Density, refractive index, optical rotation per batch |
| Chemical tests | Acid value, ester value per batch |
| Retained samples | 24-month retention for re-test and complaint verification |
- Suggested internal control: adopt HPLC fingerprinting as a routine batch-consistency check in addition to classic parameters
- Reported batch variation is typically within ±10% relative for the main phthalides
- Annual production review correlates markers with harvest quality for continuous improvement
