How do you ensure batch-to-batch consistency of Astragalus root oil?
Consistency is controlled from Dao-di raw material through release testing.
Consistency Controls
| Stage | Control |
|---|---|
| Raw material | Sourced from the same contracted GAP bases and root-age grades; incoming HPLC screening of astragaloside IV |
| Process | Fixed CO2 parameters (25–27 MPa, 50–52°C, 3–4 h) and steam parameters; SOP-locked |
| Release | GC-MS fingerprint vs Dao-di reference; marker range for astragaloside IV & calycosin-7-O-glucoside; physicochemical window |
| Records | 24-month retained samples per batch for customer-comparison or dispute testing |
- Release pass rate: 98.8% for CO2 batches; reworked or rejected lots are never shipped
- Cross-batch CV for astragaloside IV is controlled within ±10% of the certified value
- A GC-MS overlay of your original reference batch and the new batch can be provided on request
