Explore 8 core standardized functional botanicals engineered at Xi'an Sirn Bio-Tech's cGMP workshops. Complete with HPLC/UV batch assay validation, ultra-low pesticide screens, and custom mesh granulation.
Bioflavonoids represent a sophisticated cluster of secondary plant polyphenols characterized by a phenylbenzopyran core architecture (C6-C3-C6 backbone). In commercial bio-processing, procuring high-efficacy flavonoid fractions is frequently hindered by batch variance, native glycosylation profiles, solvent degradation, and co-eluting non-target tannins. For industrial enterprises across Odesa and the Black Sea region, sourcing directly from audited Chinese botanical extraction centers guarantees high bioavailability, exact aglycone-to-glycoside balances, and pharmacopeial purity verified through high-performance liquid chromatography (HPLC).
We isolate distinct chemical families: Flavonols (Quercetin, Kaempferol, Myricetin), Flavones (Luteolin, Apigenin), Flavanones (Hesperidin, Naringin), and Flavan-3-ols (Theaflavins, EGCG). Each subclass demands targeted pH-buffered hydro-ethanolic conditions to prevent degradation of phenolic hydroxyls.
Our Shaanxi facilities operate pressurized continuous resin columns utilizing non-polar to mid-polar polymeric adsorbents (AB-8, D101, and HPD-series). This process strips free monosaccharides, lipids, and heavy salts, concentrating targeted bioflavonoid fractions from raw slurries to ≥98% purity.
Bioflavonoids undergo thermolabile degradation at continuous exposures above 60°C. We implement continuous thin-film rotary evaporation and low-temperature vacuum belt drying (or flash spray drying with inert nitrogen protection), preserving native antioxidant ring configurations.

*Analytical cross-validation performed via Agilent 1260 Infinity II HPLC coupled with Diode Array Detectors (DAD) and Single Quadrupole LC/MS. Every export shipment to Odesa includes an individual lot Certificate of Analysis (COA).
Odesa functions as the undisputed maritime industrial gateway and logistics heartland for Ukraine's healthcare, chemical, and agro-processing industries. The unique commercial climate of Odesa Oblast—characterized by strong historical pharmaceutical institutions, active phytotherapy research, leading viticulture and enological centers, and expanding FMCG manufacturing—creates distinct requirements for high-spec botanical raw materials.
Odesa's pharmaceutical laboratories specialize in cardio-protective and venotonic tableting (addressing venous insufficiency and capillary fragility). Our purified micronized Purified Flavonoid Fractions (Diosmin/Hesperidin 90:10 ratio) and standardized Rutin NF11 integrate smoothly into solid-dose compounding lines. Micronized down to D90 <5 μm, our powders achieve rapid dissolution and peak bioavailability without excipient clumping during high-speed rotary compression.
The Black Sea cosmetic cluster produces high-end topical skincare formulated to counteract coastal UV exposure and wind-induced oxidative stress. Formulators integrate our Osmanthus Flower Flavonoids, Rosa Roxburghii Extract, and High-Purity Blue Copper Peptide (GHK-Cu) to inhibit matrix metalloproteinases (MMPs), diminish melanin deposition, and speed cellular renewal in anti-aging emulsified serums.
With the historic Bessarabian and Shabo wine districts positioned in direct proximity to Odesa, functional enology is expanding rapidly. Winemakers and non-alcoholic functional beverage producers utilize our Instant Black Tea Polyphenols and Fruit Anthocyanin Powders (Tart Cherry, Prickly Pear) as natural coloring agents, oxidation protectors, and astringency modulators that eliminate synthetic colorants while preserving clean-label status.
Ukrainian consumers increasingly prioritize preventative wellness, immune resilience, and adaptogenic blends. Local sports nutrition brands and contract packers in Odesa source our water-soluble Cordyceps Polysaccharides, Ginseng Extract Ginsenosides, and Spray-Dried Berry Powders for single-serve sachet stick-packs, effervescent immunity formulations, and functional dry-mix health beverages.
Global supply chain dynamics have altered traditional maritime trade routes servicing Southern Ukraine. Procuring botanical extracts requires robust logistics contingencies, temperature-controlled multimodal corridors, and unyielding compliance with Ukrainian and European pharmacopeial regulations.
Ocean container dispatch from Qingdao/Shanghai to Constanța (Romania) or Danube barge routing (Galați/Izmail/Reni) straight through to Odesa bonded terminals.
Rail-freight transit across the Eurasian corridor arriving into Polish/Slovakian intermodal hubs, transloaded to bonded TIR trucks direct to Odesa customs points.
Direct air courier from Xi'an (XIY) to Warsaw or Chișinău airport, followed by dedicated temperature-regulated road delivery within 5–7 business days for pilot batches.
All lots align with the State Pharmacopoeia of Ukraine (ДФУ) and EU Regulation 396/2005 (Pesticide limits), with GC-MS/MS 400+ pesticide screens and ICP-MS heavy metal validation.
To assist customs brokerages in Odesa, Xi'an Sirn Bio-Tech supplies certified Commercial Invoices, Packing Lists with declared Net/Gross tare weights, Phytosanitary Certificates issued by China Customs (GACC), Non-GMO Declarations, TSE/BSE-Free Certificates, and detailed production flowcharts.
Headquartered in Xi'an—the cradle of China's Qinba Mountain medicinal botanical reserve—Xi'an Sirn Bio-Tech Co., Ltd. bridges raw agricultural provenance and cutting-edge industrial isolation chemistry. We do not operate as simple repackers or brokers; our clients in Ukraine transact directly with the manufacturing source.
We maintain joint analytical research operations with Xi'an Jiaotong University, Northwest University, and Xi'an University of Science and Technology. This academic infrastructure enables molecular fingerprinting, polymorph analysis, and custom enzyme catalysis for specific bioflavonoid glycosides.
Our QC laboratory runs dual Agilent 1260 HPLC units, Shimadzu Gas Chromatography (GC-FID/ECD for pesticide screens), UV-Vis double-beam spectrophotometers, and atomic absorption spectrometers. We analyze every lot for identity, heavy metals (Pb, As, Cd, Hg), and microbial bioburden before dispatch.
With 2 standard production facilities, 4 commercial lines, and 2 pilot lines, we lower procurement barriers. Our 1 kg MOQ permits Ukrainian pharmaceutical formulation teams to execute preliminary benchtop validation and stability testing prior to committing to 25 kg fiber drums or multi-ton contracts.
Direct technical and operational clarifications regarding testing protocols, incoterms, customized blending, and regulatory dossier support for cross-border transactions.
