How is this Panax ginseng root oil extracted, and which method is preferred?
This oil is produced by supercritical CO2 extraction or steam distillation from dried Panax ginseng roots; CO2 is preferred for premium grades.
Extraction Methods
| Method | Parameters | Characteristics |
|---|---|---|
| Supercritical CO2 (standard) | 50–60°C, 20–22 MPa, 3–4 h, filling ratio 0.5–0.6 | Highest marker recovery; waxy-semi-solid oil with rich ginsengol signature |
| Sequential (patent CN1965875B) | Ethanol pre-treatment (35–45 mesh, 70–80% EtOH, 75–82°C, 3–4 h) then sc-CO2 | Improved yield; co-recovers ginseng saponins — comprehensive raw-material use |
| DES-CO2 (Jilin University) | 25–60°C, 15–45 MPa, deep-eutectic solvent + ethanol co-solvent | Gentle temperature protects heat-sensitive polyacetylenes; panaxynol-enriched; yield >1.0% |
| Steam distillation | Traditional route | Classic herbal profile, lighter body |
- The patented sequential route (CN1965875B) combines ethanol pre-treatment with supercritical CO2, significantly raising oil yield while also isolating ginseng saponin monomers
- Jilin University's DES-scCO2 technology (licensed for industrial scale-up) enriches panaxynol (anti-cancer, neuroprotective) and breaks the "low yield, low purity" bottleneck of ginseng oil production
- Steam-distilled lots are offered as a traditional, cost-effective option; CO2 lots are recommended for fine perfumery and luxury skincare
