You're entering into a cooperation with a Shaanxi Rebecca Bio-Tech manufacturer that is rooted in scientific rigor and operational excellence:

· Our team of botanists and extraction professionals in research and development work together to produce new bioavailable formulations to suit your needs.

· Industrial Scale Production: Stable product supply is ensured by three distinct production lines with an aggregated annual capacity of more than 2,000 tons.

· State of the Art Testing Facility: Pesticide residue analyzers, UPLC, HPLC, ICP-MS and GC-MS for complete quality assurance.

· International certifications in place: FSSC22000, ISO9001, HACCP, KOSHER, ECOCERT & HALAL.

· We make sure our raw materials are GAP-compliant, meaning they are free from heavy metals and pesticide residues from crop cultivation to final packaging.

· Third party tested for purity, potency and safety by SGS and BV.

Our Sophora Japonica Extract starts with the meticulous grading of raw materials:

These dried flower buds (Sophora japonica buds) originate from Hebei, Shandong, Henan and Shaanxi and are well-known for their high rutin content. They were collected throughout the summer.

Raw Material Grading:

1. Pharmaceutical/Food Grade: Freshly selected flower buds without mold and leaf contaminants. Strict testing for pesticides and heavy metals. By this procedure rutin of 95 or 98 per cent purity was obtained.

2. Raw Material: Buds and little fragments of leaf. affordable solution for 20%, 30% and 50% needs.

3. Organic Grade: Sourced from organic farms verified by ECOCERT and the USDA. Nothing is man made like pesticides and fertilizers. Contamination is avoided by using specialized processing lines.

Buds are picked and air-dried, cleansed of branches, leaves, mold and sand, and kept under regulated circumstances.

Specification Differentiation:

· Rutin is a cheap material for the production of herbal supplements and animal feed, since it contains 20% of water and 30% of alkaline.

· 50% Rutin: Standard protocol for purification of export dietary components by single-stage macroporous resin process

· Rutin with a purity level of 95% or 98% obtained by recrystallization and multiple steps of resin refining; appropriate for use in medicines, high-end supplements and anti-aging skin care products.

Solubility:

· It will be easily soluble in heat, ethanol and propylene glycol, all solvents.

· It is sparingly soluble in cold water.

· The polyols and emulsifiers needed for ointments are insoluble in oils.

Stability:

· Stable at ≤80℃; degrades over 90℃ on prolonged heating

· pH: Best between 4.0 and 7.2: hydrolysis is rapid in highly alkaline circumstances.

· Dry powder is stable when protected from direct sunshine, but water-based solutions oxidize and yellow under UV radiation.

· Humidity: The greater purity is related to the lesser hygroscopicity. 95%/98% grades absorb relatively little water. Shelf life 24 months. Store in a cool, dark area, maintain sealed.

I. Raw Material Pretreatment

Acceptance and sorting of dried buds → Low-temperature drying (45–55℃) → Crushing to 20–30 mesh

II. Extraction

20%/30%: Alkaline hot water (90–95℃, pH 8.0–9.0) 50%/95%/98%: Dilute ethanol + alkaline water (75–80℃, 0.5% Na₂CO₃)

III. Filtration & Acid Precipitation

Coarse + plate filtration → pH adjustment to 3.0–4.0 → Rutin precipitates → Centrifuge and wash

IV. Purification

20%/30%: Direct concentration 50%: D101 resin + 45% ethanol elution 95%/98%: Resin + multi-stage hot water recrystallization

V. Drying

Low purity: Spray drying (155℃ inlet) High purity: Vacuum drying (45–50℃)

VI. Finishing

Sieving (60–200 mesh) → Blending → Vacuum-sealed light-proof packaging (25 kg drums)

VII. Testing

HPLC (rutin %), ICP-MS (heavy metals), GC-MS (pesticides, solvents), microbiology → COA/MSDS issued

Key Control Points: Raw material baseline testing, pH adjustment during precipitation, recrystallization cycles, drying temperature, and final particle size classification.

We maintain end-to-end quality control:

· Compliance with HACCP, ISO9001 and FSSC22000 certification systems

· Heavy metals, pesticide residues, solvent residues, microbiological and in-house testing by HPLC, UPLC, ICP-MS, GC-MS

· Full chain of custody documentation; batch specific certificates of analysis and material safety data sheets

· SGS and BV re-inspection supported by third party validation

Standard Packaging:

· Inside: a light and moisture-proof vacuum-sealed aluminium foil bag

· Outer: 25 kilogram cardboard drum

Custom Options:

· 1kg, 5kg, or 10kg sizes

· Neutral brand for OEM/ODM projects

· Temperature sensitive shipping packaging

Delivery Methods for Sophora Japonica Extract:

· Express: FedEx, DHL (small orders)

· Air freight: For urgent, medium volume shipments

· Sea freight: Economical for large orders

Q: How soluble is rutin in cold water for oral liquids?

A: It is slightly soluble in cold water. For liquid formulations, use 200 mesh ultrafine powder with Propylene glycol or warm gently to avoid precipitation.

Q: Will rutin degrade in high-temperature processing?

A: Work below 80℃. Hydrolysis occurs after extensive exposure (>90 °C). Keep pH 4.0 - 7.2 Avoid extremely alkaline systems.

Q: How hygroscopic is the product during shipping?

A: Higher purity (95%/98%) is less hydroscopic. Our double-layer, light-proof and moisture-proof packaging prevents clumping during ocean transport.

Q: Can you customize mesh size, content, and packaging?

A: Yeah.  We may customize the quantity of Rutin, particle size (60-300 mesh) and neutral Export Packaging. Our own factory will take care of huge volume requirements reliably.

Q: Do you provide third-party testing and stability data?

A: Definitely. Re-inspection by SGS/BV is supported. we offer COA, MSDS and stability studies for regulatory submission
