Ginkgo Biloba 24/6 extract should be qualified by flavone glycosides, terpene lactones, ginkgolic acid limits, botanical identity, HPLC data and batch-specific documentation.
The term “24/6” should be treated as a specification framework rather than a complete quality statement. Buyers still need to confirm the exact assay method, actual batch results, contaminants, plant part and product grade.
1. What Is Ginkgo Biloba 24/6 Extract?
Ginkgo Biloba extract is a botanical ingredient obtained from Ginkgo leaves. A standardized 24/6 profile generally refers to target levels of flavone glycosides and terpene lactones, subject to the applicable product specification.
Buyers should confirm the botanical identity, leaf source, extraction ratio, carrier, standardization, testing method and ginkgolic-acid limit before approving a supplier.
2. Key Ginkgo Biloba Specifications
Flavone Glycosides
Flavone glycosides are one of the key standardization parameters for Ginkgo Biloba extracts. The buyer should confirm the numerical result, analytical method and reference standard.
Terpene Lactones
Terpene lactones should be listed as a separate specification where required. They should not be assumed from the total flavone-glycoside result.
Ginkgolic Acids
Ginkgolic acid control is an important quality and safety parameter for standardized Ginkgo extracts. Buyers should request the limit, analytical method and batch result.
Botanical Identity
The product should identify Ginkgo biloba and the plant part used. A botanical identity or fingerprint method may be required according to the customer quality system and destination market.
3. How to Review a Ginkgo Biloba COA
A complete COA should connect the actual batch with the 24/6 standardization, ginkgolic-acid result and contaminant panel.
- Product name and botanical identity.
- Plant part and origin where available.
- Batch or lot number.
- Flavone-glycoside result.
- Terpene-lactone result.
- Ginkgolic-acid result.
- Assay method and reference standard.
- Heavy-metal results.
- Pesticide-residue results.
- Microbiological results.
- Moisture, ash and physical properties where applicable.
- Manufacturing date, expiry or retest date.
- Storage and packaging conditions.
A report that only states “Ginkgo 24/6” without showing the actual flavone-glycoside, terpene-lactone and ginkgolic-acid results is incomplete for a technical purchase.
4. Contaminant and Authentication Control
Buyers should review:
- Heavy metals.
- Pesticides.
- Microbiological contamination.
- Botanical identity.
- Ginkgolic acid control.
- Residual solvents where applicable.
- Moisture and storage conditions.
The required limits depend on the product category and destination market. Buyers should agree on the specification before placing the purchase order.
5. How to Compare Ginkgo Biloba Quotations
Compare Ginkgo Biloba products by the complete 24/6 specification, not only by the headline flavone-glycoside percentage.
| Comparison Item | Question to Ask |
|---|---|
| Standardization | Are both flavone glycosides and terpene lactones specified? |
| Ginkgolic acids | Is there a numerical limit and batch-specific result? |
| Analytical method | Is the HPLC method defined and suitable for the matrix? |
| Contaminants | Are heavy metals, pesticides and microbiology included? |
| Commercial terms | Are MOQ, packaging, lead time and delivery terms stated? |
6. Buyer Qualification Checklist
- Confirm the botanical identity and leaf source.
- Confirm the flavone-glycoside specification.
- Confirm the terpene-lactone specification.
- Request the ginkgolic-acid limit and result.
- Review the HPLC method and batch COA.
- Check heavy metals and pesticide residues.
- Review microbiology and residual solvents where applicable.
- Confirm moisture, particle size and storage conditions.
- Evaluate the product in the intended formulation.
- Confirm MOQ, lead time and destination-market documentation.
Frequently Asked Questions
What does Ginkgo Biloba 24/6 mean?
24/6 generally refers to target levels of flavone glycosides and terpene lactones in a standardized Ginkgo Biloba extract. Buyers should confirm the exact specification and assay method.
Why do ginkgolic acid limits matter?
Ginkgolic acids are an important quality-control parameter for Ginkgo Biloba extracts. Buyers should request the applicable limit, test method and batch-specific result.
How should I review a Ginkgo Biloba COA?
Check the botanical identity, flavone glycosides, terpene lactones, ginkgolic acids, assay method, batch number, heavy metals, pesticides and microbiology.
What is an HPLC fingerprint?
An HPLC fingerprint is a chromatographic profile used to compare the characteristic chemical pattern of a botanical material. It should be interpreted with the specification and other identity controls.
Can Ginkgo Biloba 24/6 be used in dietary supplements?
Some grades may be suitable for supplement formulation development. The buyer should confirm the specification, ginkgolic-acid control, contaminants and destination-market requirements.
Can Blueeyes Bio provide Ginkgo Biloba 24/6 documentation?
Blueeyes Bio can discuss available Ginkgo Biloba grades, marker specifications, technical documents and commercial quantities according to the buyer’s application and destination market.
