Ginkgo Biloba Folium Extract

Shaanxi Rebecca Biotechnology delivers stable, high-quality botanical extracts with mature R&D and full industrial production capacity. We adopt optimized low-temperature extraction and ultra-fine grinding technology to fully retain heat-sensitive active ingredients, avoiding ingredient loss and performance degradation caused by traditional high-temperature processing.

We continuously upgrade extraction processes to maximize flavonoid and terpene yield while strictly reducing harmful impurities. Our scalable production lines flexibly meet small-batch trial orders and large-scale commercial bulk orders. Every batch of Ginkgo Biloba Folium Extract is fully monitored during production and tested by in-house HPLC, ICP-MS and pesticide residue detection equipment, fully complying with USP, EP and global regional food and drug regulations. Supported by ISO22000, cGMP, HACCP, HALAL and KOSHER certifications, we provide customized mesh size, product grade and packaging solutions to match your unique formulation requirements.

All raw ginkgo leaves are sourced from standardized ecological planting bases with suitable soil pH, sufficient sunlight and fertile loam soil. We cooperate with professional agronomic teams to implement scientific fertilization, fixed-cycle watering and targeted harvesting, ensuring raw materials are picked at the peak of active ingredient accumulation for stable and consistent quality.

Before mass production, all raw materials undergo strict manual screening and instrumental testing to remove deteriorated leaves, fruit and seed impurities, with full heavy metal and pesticide residue detection. We provide complete batch traceability records covering planting, harvesting and production processes to support customer audits and global product registration. We offer three mainstream grades: 10:1/20:1 ratio extracts for cost-effective conventional applications, standard 24/6 high-activity grade for mainstream health supplements, and premium low-ginkgolic acid grade for high-standard cosmetic and sensitive-use scenarios.

This ginkgo extract can be partially dispersed in cold water, with significantly improved solubility in hot water or ethanol-water mixed solvents. Minor natural sediment may appear after dissolution, which is a normal characteristic of pure botanical ingredients and does not affect product safety and efficacy.

We adopt low-temperature concentration and spray drying below 60°C to effectively protect terpene lactones from thermal decomposition. Sealed powder maintains stable efficacy for 24 months under specified storage conditions. Its active flavone glycosides remain stable in pH 4–7 environments, compatible with most mainstream formulation systems. Note that long-term UV exposure and high-oxygen environments will cause active ingredient degradation, so opaque moisture-proof packaging and inert gas protection are recommended for liquid finished products.

We implement standardized and refined production procedures to ensure batch consistency:

1. Raw material sorting, crushing and pre-production quality inspection to eliminate unqualified materials;

2. Multi-stage food-grade ethanol reflux extraction to fully dissolve target active ingredients;

3. Precision filtration to separate leaf residues and extract liquid;

4. Low-temperature vacuum concentration (below 60°C) to protect active activity;

5. Macroporous resin purification to remove ginkgolic acid, tannins and miscellaneous sugars;

6. Fine filtration to remove tiny micro-impurities;

7. Spray drying to turn purified concentrate into uniform dry powder;

8. Milling and sieving to reach 80–100 mesh standard fineness;

9. Homogeneous blending and full-index QC testing for each batch;

10. Sealed packaging in moisture and light-proof environment.

Every batch is delivered with official COA reports, including complete HPLC chromatograms, ginkgolic acid test data, residual solvent detection results (compliant with ICH Q3C standards) and microbial safety indicators. Third-party independent testing is supported upon customer request. Our whole production process follows ISO22000 and cGMP quality management systems, realizing full-process traceability from raw material incoming inspection to finished product delivery, effectively guaranteeing stable and reliable product quality for long-term cooperation.

We adopt standard industrial packaging: 25kg fiber drums with double PE inner bags and aluminum foil lining for full moisture and light protection. For laboratory research and pilot tests, customized small packages of 1kg, 5kg and 10kg are available, with private label and personalized packaging services supported.

We provide diversified global logistics solutions: DHL/FedEx/UPS express for urgent sample orders, air freight for medium-volume time-sensitive shipments, and sea freight for large-bulk commercial orders. We support multiple trade terms such as EXW, FOB, CIF and DDP, with complete shipping documents including packing list, bill of lading, COA and MSDS to ensure smooth customs clearance and delivery.

Q1: What testing methods are used for active ingredient detection?

A1: We use professional HPLC to quantify ginkgo flavone glycosides and terpene lactones. Each batch comes with complete HPLC test spectra, and third-party authoritative testing is acceptable.

Q2: Can the ginkgo extract be fully dissolved in water?

A2: It can be partially dispersed in cold water. Dissolubility is better in hot water or ethanol-water mixed solvents. Slight sediment is normal for pure botanical extracts with complete active retention.

Q3: What grades do you offer for ginkgolic acid content?

A3: Two grades are available: standard grade with ginkgolic acid ≤5ppm, and premium low-acid grade with ginkgolic acid ≤1ppm, suitable for cosmetics and high-safety requirement scenarios.

Q4: What storage conditions ensure long-term stability?

A4: Store the powder sealed in a cool, dry and dark environment. Avoid high temperature, strong light and long-term air exposure to prevent active ingredient oxidation and failure.

Q5: Do you support customized specifications and packaging?

A5: Yes. We support customized mesh size, special purity grades and private label packaging, meeting personalized needs for laboratory research, small-batch trial production and mass commercial production.

Q6: What certification documents can be provided?

A6: We can provide ISO22000, cGMP, HACCP, HALAL, KOSHER certification copies, complete COA, MSDS and other registration documents to support global market sales.
