Why Choose Us
Every batch of Hypericum Perforatum Extract Powder that Shaanxi Rebecca Biotechnology Co., Ltd. makes is made with skill that has been tested and proven.
Advanced Technology: Our plant uses high-temperature drying and ultra-fine grinding technology to keep the active ingredients and make sure the particles are spread out evenly.
Quality Infrastructure: Our business has a lot of different certificates, such as ISO9001, ISO22000, FSSC22000, HACCP, HALAL, KOSHER, and cGMP. Our 100,000-grade laboratory ensures that our products will be made without any pollution.
Testing Capabilities: We have HPLC, UV-Vis spectrophotometry, and other high-tech screening tools that we use to do thorough tests on-site to check for hypericin, heavy metals, chemical residues, and bacteria poisoning. Verification by a third party adds another level of security.
Flexibility in customisation: Need exact details? We offer OEM/ODM services and can make powders, pills, and hard capsules in a variety of dosage types to meet your specific needs.
Global Supply Chain: Our effective transportation network makes sure that everywhere in the world is delivered safely and on time. We keep our store amounts steady so that we can meet your ongoing output needs.

Source & Traceability
Our ingredients come from carefully chosen growing areas where St. John's Wort grows naturally well.
Premium Origins: We get our materials from two main grades:
· European Grade: Comes from Germany and Poland and has more active ingredients and stricter chemical control for high-quality goods that meet standards.
· Domestic Grade: High-quality materials from Shaanxi and Gansu areas that provide great value for ratio extracts.
Standards for Harvesting: Plants are picked by hand during peak growth, when the amount of hypericin is highest. Before it is processed, each batch is carefully screened to get rid of weeds, dead twigs, and mouldy materials.
Traceability System: Every lot comes with full paperwork that lets you track everything from the field to the finished product. If asked, organic batches can show ECOCERT and USDA organic licenses.

Solubility & Stability Profile
Understanding the basic properties helps you make the best formulations.
Solubility Characteristics:
· It dissolves easily in ethanol and propylene glycol
· Can be mixed with hot water
· Not completely dissolved in cold water
· Not soluble in vegetable oils (needs emulsifiers for ointment use)
Stability Parameters:
· Temperature: stable up to 75°F; don't process above 85°F
· pH Range: most stable between 3.5 and 7.0; breaks down in strong acids or bases
· Light Sensitivity: Hypericin is very sensitive to light and needs to be stored and packaged in a way that keeps light out.
· Moisture: moderate hygroscopicity; double-layer covering to keep out moisture is suggested

Manufacturing Process
1. Pretreatment: Remove weeds and defective parts, dry at 50–60°C, and pulverize to 20 mesh, while conducting a raw material purity check.
2. Extraction: Perform reflux extraction with ethanol‑water solvent at 60–70°C for 2–3 cycles, strictly monitoring temperature and extraction time.
3. Filtration: Apply multi‑stage filtration (coarse, plate‑and‑frame, and cartridge) to verify liquid clarity.
4. Concentration: Concentrate under vacuum at ≤70°C while recovering ethanol, with careful temperature control.
5. Purification: Enrich via macroporous resin to meet standardized specifications, adjusting hypericin content as required.
6. Drying: Use spray drying for standard products or vacuum drying for high‑content versions, and test the final moisture content.
7. Quality Control: Perform HPLC assay, pesticide screening, heavy metal testing, and microbiology analysis, and issue a Certificate of Analysis.

Quality Assurance
We keep a close eye on quality throughout the whole creation process.
Certification System: All of the Hypericum Perforatum Extract Powder meets the requirements of EU EC396, EU 2023/915 standards, and global liquid residue limits. Our certificates include proof that we are non-GMO and vegan.
Testing Procedures: Each batch is fully checked for hypericin levels, herbicide leftovers (below measurement limits), heavy metals (especially cadmium levels), and bacteria contamination.
Traceability: Full batch tracking is possible with full paperwork from the time the raw materials are sourced to the time they are packaged.
Third-Party Verification: Testing in a separate lab proves the product's safety, quality, and effectiveness.

Packaging & Delivery
It comes in a double-layer PE bag and a fibre drum that weighs 25 kg. Photosensitive chemicals are kept safe during shipping by closing them off from light and moisture.
Custom Options: If you need custom wrapping, like smaller amounts, a different type of container, or your own name, just let us know.
Shipping Options: We ship all over the world by air freight (for pressing orders) or sea freight (for cheap large shipping). When needed, our transportation partners make sure that transport is kept at the right temperature.

Certificates
As a specialized export-oriented supplier of natural plant extracts and synthetic chemical raw materials, Shaanxi Rebecca Bio-Tech Co., LTD,. has obtained authoritative ISO9001 quality management system certification.

Frequently Asked Questions
Q: How do the 0.3%, 0.5%, and 1.0% specifications differ?
A: 0.3% uses basic resin purification for mainstream supplements. 0.5% undergoes enhanced purification for premium products. 1.0% represents multi-stage enrichment producing high-purity concentrate for specialized applications.
Q: Will the powder remain stable during shipping?
A: Yes. Our light-proof, moisture-sealed packaging prevents photodegradation and clumping during standard ocean transport. The product remains stable when kept below 75℃ and away from direct light.
Q: Are your raw materials harvested at optimal potency?
A: Absolutely. We harvest manually during peak flowering when hypericin content reaches maximum levels. Each batch is screened upon arrival to remove inferior materials.
Q: Can you provide organic certification?
A: Yes. We offer organic-certified batches with ECOCERT and USDA organic traceability documentation for qualifying lots.
Q: What's your minimum order quantity?
A: We accommodate various order sizes. contact us at information@sxrebecca.com to discuss your specific requirements and receive a competitive quotation.
