Ginseng is one of the most recognised botanicals in the world, and one of the easier extracts to buy badly. Because ginsenoside content is what carries the value, and because other Panax species and lower-grade root are routinely passed off as premium Panax ginseng, the specification you write — and the analytical proof you demand — matters more here than for a commodity herb. This guide covers how to specify ginsenoside grade, what a genuine Certificate of Analysis must show, and how to avoid the quality traps.
What Is Ginseng Extract?
Ginseng extract is a concentrated, standardised preparation made from the dried roots of Panax ginseng C.A. Mey. — Asian, or “Korean”, ginseng, used for centuries in East-Asian medicine as a tonic and adaptogen. The root is the ginsenoside-rich part of the plant, and a concentrated extract is a practical way to deliver a defined active load at a controlled, repeatable specification rather than relying on variable raw root powder.
The characteristic constituents are the ginsenosides — triterpene saponins split into the panaxadiol group (Rb1, Rc, Rd) and the panaxatriol group (Rg1, Re). A serious commercial extract is standardised to its total ginsenoside content, because ginsenosides are the industry-recognised marker for the material and the compounds most closely associated with its traditional use.
How to Specify Grade: Total Ginsenosides
The specification line that defines a ginseng extract is its total ginsenoside content. SV Botanica supplies three standard grades — ginsenosides not less than 10%, 20% and 30% w/w, measured by HPLC. Ginsenosides govern both the traditional positioning and the standardised-active claim, so a defined ginsenoside figure is what lets a formulator replace undefined root powder with a specified ingredient.
Buyer tip: Insist that the ginsenoside percentage and the method (HPLC) appear on the CoA itself — not just in a sales email. A “ginseng extract” quoted with no marker percentage, or on a vague “extract ratio” alone, tells you nothing about the active load. For the analytical detail behind the marker, see our guide to ginsenosides and how ginseng extract is standardised.
Why the Species Matters
Only the root of true Panax ginseng carries the characteristic ginsenoside profile buyers expect. Material that quietly includes other Panax species — American ginseng (P. quinquefolius) or notoginseng (P. notoginseng) — lower-grade root, or exhausted root already stripped of actives is cheaper to produce and visually similar, but analytically different. A root-only, correct-species declaration, backed by an HPLC ginsenoside fingerprint that matches reference material, is your first line of defence. We cover the mechanics of this in ginseng adulteration and authenticity.
What a Genuine Ginseng Extract CoA Must Show
Because ginseng commands a premium over ordinary root powders and is a known substitution target, the Certificate of Analysis carries real weight. A complete, trustworthy CoA should include every line below. These are the specification limits SV Botanica supplies against document SVB/QC/PS/PG/001.
| Parameter | Specification / Limit | Method |
|---|---|---|
| Identification | HPLC ginsenoside profile to comply with reference material | By HPLC |
| Total ginsenosides | NLT 10 / 20 / 30% w/w (by grade) | By HPLC |
| Loss on drying | NMT 6.0% | USP <731> |
| Solubility | Soluble in water | In-house |
| Particle size (#80 mesh) | NLT 95.0% w/w | USP <786> |
| Residual solvents | To comply with USP limits | USP <467> |
| Lead / Arsenic / Cadmium / Mercury | NMT 5.0 / 2.0 / 0.5 / 0.2 ppm | ICP-MS |
| Microbiology (TPC / Y&M / pathogens) | NMT 5,000 / NMT 100 / negative | USP <2021>/<2022> |
| Shelf life | 36 months from manufacture | — |
The heavy-metal and microbiological blocks deserve particular scrutiny for a root-derived botanical grown in soil. A CoA that states only “complies” without a method and per-element limits is not adequate.
Why Source Ginseng Extract from India?
India is a mature, export-oriented herbal-extract manufacturing base with the standardisation and analytical capability built for regulated markets. Sourcing standardised ginseng extract directly from Indian manufacturers brings real advantages: HPLC standardisation and species authentication, competitive direct-from-manufacturer pricing, and full documentation packages — CoA, MSDS, and declarations covering irradiation and GMO status — issued per batch.
What to Ask Your Supplier
When evaluating ginseng extract suppliers for commercial supply, request the following as a minimum:
- Batch-specific CoA stating total ginsenoside % by HPLC
- HPLC ginsenoside identity profile confirming compliance with reference material
- Root-only, correct-species (Panax ginseng) declaration and country of origin
- Heavy-metal report by ICP-MS with numeric limits for Pb, As, Cd, Hg
- Solubility and mesh figures
- Residual solvents and full microbiological panel
- Declarations: non-irradiated, GMO-free
