Sophora Japonica Extract (derived from the Flos Sophorae Immaturus or Pagoda Tree buds) is one of the most commercially critical botanical sources for active bioflavonoids. Its primary chemical isolates, Rutin (quercetin-3-rutinoside) and its aglycone derivative Quercetin, are crucial components in modern pharmacology, nutraceutical formulation, and high-performance skincare.
Global pharmaceutical and dietary supplement enterprises demand strict adherence to international monograph criteria, including USP, European Pharmacopoeia (EP), and Chinese Pharmacopoeia (CP). For professional procurement managers, analyzing critical parameters such as assay purity, residual solvents (specifically keeping ethanol within safe ICH guidelines and avoiding toxic methanol), pesticide residues (in line with USP <561>), and heavy metals levels is paramount. Sourcing high-quality Sophora Japonica Extract directly from a qualified Chinese factory ensures complete traceability from the agricultural source to the finished active pharmaceutical ingredient (API).
Shaanxi Province, specifically the Hi-Tech Zone of Xi'an, is internationally designated as the core cluster for botanical extraction. The natural geographic advantage of the Qinling Mountains yields an abundant supply of premium raw botanicals. Localized cluster operations allow manufacturers like Shaanxi ShineHerb Biotech Co., Ltd. to benefit from specialized R&D talent, shared testing facilities, and streamlined export customs procedures.
By scaling operations and integrating agricultural cultivation partners directly, Chinese factories mitigate volatile raw material costs. ShineHerb Biotech maintains advanced large-scale extraction vessels, counter-current extraction systems, and industrial-scale column chromatography setups. This robust infrastructure guarantees that wholesale batches meet strict specifications with high consistency, minimizing lot-to-lot variance that often compromises large-scale manufacturing runs in Europe or North America.
To ensure total transparency, our standard analytical criteria for Sophora Japonica extracts and derivatives meet or exceed international regulatory thresholds.
| Active Compound | Botanical Source | Standard Specification | Testing Method | Regulatory Compliance |
|---|---|---|---|---|
| Rutin Trihydrate | Sophora japonica L. (Flos) | ≥ 95.0% - 101.5% | HPLC / UV-Vis | EP / USP / NF11 / CP |
| Quercetin Anhydrous | Hydrolyzed Rutin Bud | ≥ 95.0% / ≥ 98.0% | HPLC | Dietary Supplement Grade |
| Troxerutin | Semi-synthetic (from Rutin) | ≥ 98.0% | HPLC | EP / USP Venotonics Standard |
| Genistein | Sophora japonica L. (Fruit) | ≥ 98.0% | HPLC | Non-GMO Menopause Support |
In capsule, tablet, and powder formulations, Quercetin acts as a powerful ionophore. When coupled with Zinc, it supports cellular defenses, cardiovascular wellness, and capillary resilience. Procuring standard mesh sizes (such as 80 mesh or superfine 200 mesh) is critical for high-efficiency capsule filling and stable tableting processes.
Rutin and Troxerutin serve as exceptional topical active ingredients designed to minimize redness, alleviate oxidative stress, and protect dermal microcapillaries. Sourcing a high-solubility, skin-penetrating extract grade ensures seamless integration into anti-aging serums and barrier-repair lotions without recrystallization.
As a precursor for advanced semi-synthetic flavonoid drugs, wholesale-grade Sophora Japonica extracts are subjected to strict regulatory inspections. ShineHerb Biotech supplies bulk API-grade materials under GMP conditions, providing full documentation (COA, MSDS, GMO statements) required for regulatory submission.
