Product Introduction
Sophora Japonica Extract - 95% Rutin & 95% Quercetin
Organic Herb Inc. manufactures pharmaceutical-grade botanical extracts from GAP-certified sources. Our Sophora Japonica Extract delivers standardized 95% Rutin and 95% Quercetin for nutraceutical and cosmetic formulations.
Stock Number:872213 (Freely Traded)
Certifications:NSF GMP, FSSC22000, ISO9001, HALAL, KOSHER
We work 8,000+ sections of land of controlled planting bases and keep up $1.2M in explanatory gear (HPLC-ELSD, GC-MS, LC-MS/MS). Our 27-member R&D group has created over 400 standardized home grown extracts.

What Makes Our Sophora Japonica Extract Stand Out
Source & Traceability
Our extricate comes fromStyphnolobium japonicumflower buds collected over three GAP-certified bases in Shaoyang, Changsha, and Guizhou provinces.
We work specifically with contracted ranchers, giving specialized back from seedling determination through collect timing. This disposes of supply chain middle people and ensures full traceability to particular development lots.
Extraction Technology
We utilize energetic low-temperature extraction combined with nano-membrane confinement. This method:
· Jam heat-sensitive flavonoid structures
· Minimizes dissolvable buildups (confirmed by GC analysis)
· Produces reliable crystalline powder
For Quercetin specifically:Our controlled enzymatic hydrolysis guarantees total transformation from Rutin with zero leftover glycosides. This things for atomic weight determinations and bioavailability in your formulations.
Quality Meets Pharmacopeia Standards
Final items meet USP, EP, and CP benchmarks. You receive:
· Rutin:Greenish-yellow crystalline powder
· Quercetin:Bright yellow powder, completely hydrolyzed aglycone form
Both pass through 80-mesh screens (95% least) for ideal stream properties in tableting and encapsulation.

Quality Control Process
Every Sophora Japonica Extract batch goes through six verification stages before release:
1. Raw Material Authentication
HPLC fingerprint analysis distinguishes genuine Sophora japonica from adulterants or synthetic flavonoids.
2. Pesticide Screening
Multi-residue LC-MS/MS testing covers 500+ pesticides per EU and FDA regulations.
3. Solvent Residue Verification
GC analysis confirms ethanol residues fall below regulatory limits (USP <467>, ICH Q3C).
4. Potency Validation
For Quercetin batches: We verify complete hydrolysis of Rutin. Residual glycosides would alter molecular weight and reduce bioavailability.
5. Microbial Safety Testing
· Salmonella: Negative (25g sample)
· E. coli: Negative
· Total Plate Count: <1000 cfu/g
6. Heavy Metals Analysis
Atomic absorption spectrophotometry confirms levels <10ppm.
Documentation:Each COA includes full traceability to harvest batch, extraction date, and analytical test results. All records support GMP audit requirements.

Application Solutions for Your Industry
Nutraceutical Tablets & Capsules
The 95% pass 80-mesh specification ensures excellent flow properties and compression. Standardized potency simplifies supplement facts calculations.
Bulk density (0.4-0.6 g/ml)works with most volumetric filling equipment without recalibration.
Liquid Formulations
Rutin shows limited water solubility. Our technical team can assist with:
· Alkaline solubilization methods
· Enzymatic modification strategies
· Compatibility with your processing equipment
Cosmetic Applications
Quercetin's antioxidant activity (verified by ORAC testing) makes it suitable for anti-aging serums and emulsions. The bright yellow powder disperses readily in cosmetic bases.
Note:Product is light-sensitive. We provide packaging recommendations based on your final container type.
Frequently Asked Questions
Q: What extraction strategy do you use?
A: Energetic low-temperature extraction with nano-membrane separation. We utilize water and ethanol solvents. Last dissolvable buildups are confirmed by GC examination to meet pharmacopeia standards.
Q: How do you guarantee clump consistency?
A: Each generation run experiences HPLC unique mark coordinating against reference guidelines. We screen 15 basic quality properties through factual handle control. Irregular tests get extra third-party testing.
All documentation takes after GMP traceability requirements.
Q: What's the contrast between your Rutin and Quercetin products?
A: Rutin is the normal glycoside frame (Quercetin-3-O-rutinoside) extricated straightforwardly from bloom buds.
Quercetinis the aglycone gotten through controlled enzymatic hydrolysis of Rutin. We confirm total change and test for nonappearance of remaining glycosides. This guarantees you get the particular atomic frame your detailing requires.
Q: Can you give custom specifications?
A: Yes. We've created 400+ botanical extricates with 100+ standardized variations.
Custom alternatives include:
· Elective molecule estimate distribution
· Distinctive power levels (contact us for feasibility)
· Specialized testing protocols
Our R&D group works with you to meet specialized and administrative requirements.
Q: What documentation do you give for administrative filings?
A: Each shipment includes:
· Certificate of Analysis
· Allergen statement
· BSE/TSE declaration
· GMO-free certification
· Radiation-free attestation
For pharmaceutical applications, we give Medicate Ace Record (DMF) bolster. Solidness thinks about, security assessment information, and prepare depictions are accessible for administrative submissions.
Q: What are your lead times and least orders?
A:Stock specifications:10 days
US stockroom inventory:2-3 trade days
Minimum order:25kg
Free tests accessible for capability testing some time recently bulk orders.
