Rutin 95% NF11/EP Powder (Sophora Japonica Extract)

What is Rutin 95% NF11/EP Powder?

Rutin 95% NF11/EP Powder is a high-purity crystalline bioflavonoid compound extracted from the dried buds of Софора джапоника л- да. Standardized to a minimum of ≥95.0% purity on an anhydrous basis, this active botanical ingredient complies with official US National Formulary (NF11) and current European Pharmacopoeia (EP) monograph specifications.

The refinement process incorporates a managed impurity control pipeline, ensuring tightly restricted concentration levels of heavy metals and related flavonoids, specifically free quercetin, to satisfy international regulatory entry barriers. Manufacturing runs executed by Green Spring Technology proceed under verified GMP-certified protocols tailored for industrial B2B pharmaceutical and nutraceutical applications.

This compendial-grade bulk powder features standardized physical properties, including a particle size profile of 100% through 80 mesh and controlled residual solvent metrics within legal international thresholds. Complete batch traceability structures, structured ready-to-ship inventory controls, and full technical documentation packets consisting of КЖПХ (HPLC)-verified COAs and comprehensive MSDS sheets are systematically available to accelerate vendor qualification timelines across Western healthcare markets.

• Dry Functional Powder Blends
  This standardized Sophora japonica rutin powder features reliable miscibility for inclusion into powdered meal replacements, protein drink matrixes, and sports nutrition powder premixes. The controlled moisture threshold and low hygroscopicity prevent premature moisture absorption and particle agglomeration, maintaining steady powder flowability in automated stick pack filling equipment and canisters.

• Veterinary Supplements & Animal Nutrition
  Utilized as a high-potency bioflavonoid additive in canine and feline wellness supplements and premium pet foods. The standardized compendial-grade Rutin bulk supply provides predictable blending coefficients for companion animal formulations, supporting vascular integrity, metabolic stability, and systemic immune health.

Technical FAQ

Q1: What testing methodologies and standard limits are applied to control critical impurities, such as free quercetin, in NF11/EP grade Rutin powder?

A: Validated High-Performance Liquid Chromatography (HPLC) assays are utilized to monitor the impurity profile of Rutin 95% powder in strict accordance with USP/NF and European Pharmacopoeia (EP) monographs. The refining process restricts free quercetin to ≤4.0% (EP Monograph Limit), and maintains individual related flavonoids or unknown impurities within pharmacopeial specifications. Each production batch is accompanied by an HPLC chromatogram to verify batch-to-batch consistency and regulatory compliance for international nutraceutical and pharmaceutical markets.

Q2: Rutin is notoriously hydrophobic. How does this 95% NF11/EP specification behave in water-soluble or liquid oral formulations?

A: Standard Rutin 95% NF11/EP Powder is practically insoluble in water (approximately 0.125 g/L) and poorly soluble in anhydrous ethanol, making it prone to precipitation in liquid matrices. The ingredient is technically compatible with solid dosage forms, including hard-shell capsules and tablets. For functional beverages or clear liquid oral formulations, processing options include alkaline solubilization, co-solvents, or transitioning to a cyclodextrin-encapsulated water-soluble rutin grade to prevent sedimentation and preserve clarity.

Q3: What are the physical profiles (tapped density and particle size) of NF11/EP Rutin powder, and what are the recommendations for high-speed tablet compression?

A: The compendial-grade Rutin powder exhibits a physical profile with a tapped density of 0.40–0.60 g/mL and a particle size of 100% through 80 mesh. High-purity rutin crystals inherently exhibit lower flowability and static charge during processing. For Direct Compression (DC) tablet processing, the incorporation of standard glidants (such as 0.5% Silicon Dioxide) is advised. Alternatively, a customized, free-flowing granular grade is available to optimize high-speed tableting lines.
