Premium Standardized Natural Active Ingredients for Dietary Supplements & Pharmaceuticals
Natural Proanthocyanidins (OPCs/PPCs) represent one of the most potent classes of natural antioxidants found in the plant kingdom, extracted predominantly from Grape Seed, Pine Bark, and Cranberries. As global demand shifts toward clean-label, plant-derived, and high-bioavailability compounds, global supplement, cosmetic, and food brands require a reliable, high-purity supply chain partners.
Our extraction tech targets specific degrees of polymerization (DP), stabilizing active Oligomeric Proanthocyanidins (OPC) fractions. This delivers exceptional biological activity, water solubility, and chemical stability, satisfying the exact standards of the United States Pharmacopeia (USP) and European Pharmacopoeia (EP).
Choosing a reliable proanthocyanidins manufacturer goes beyond raw material cost. It demands an evaluation of solvent purity, monomer/oligomer ratio analysis, environmental compliance, and trace chemical documentation. Shaanxi ShineHerb Biotech operates at the intersection of technology, reliability, and precision production.
Innovating raw material stability and bioavailability through green extraction tech and smart molecular fractionation.
We use advanced membrane separation technology to isolate the low degree of polymerization (DP ≤ 5) oligomers. This optimizes intestinal absorption and cellular bioavailability compared to high molecular weight polymers.
We avoid chlorinated hydrocarbons, utilizing water and food-grade ethanol as solvents. This guarantees compliant pesticide and solvent residue thresholds, fulfilling rigorous European market standards.
Our research includes liposomal and microencapsulated forms. This masks astringent flavors and safeguards OPCs from gastric acid degradation, enhancing absorption rates in functional beverages.
How we tailor standardized Proanthocyanidins to match multi-industry applications.
Standardized ingredients must integrate with your final dosage form. We offer custom manufacturing across multiple applications:
Located in the Hi-Tech Zone of Xi'an, Shaanxi Province, ShineHerb Biotech leverages a highly optimized botanical extraction cluster. Our China Factory 4.0 integration guarantees stable, year-round production scaling and supply chain security.
Our facility runs continuous counter-current extraction systems linked to real-time PLC automation. This configuration yields optimal throughput while minimizing batch variation and lowering energy footprints.
This automated supply chain shields procurement partners from price fluctuations. With scalable manufacturing capacity and access to direct agricultural hubs, we guarantee uninterrupted production lines for your brand.

Technical answers to support your research, formulation, and commercial procurement decisions.
Oligomeric Proanthocyanidins (OPC) consist of lower degrees of polymerization (DP 2 to 5), which are highly water-soluble, bioavailable, and display stronger free-radical scavenging capacity. Polymeric Proanthocyanidins (PPC) have a DP > 5, rendering them less soluble and harder to absorb in the digestive tract. Standardized extracts prioritize a high ratio of OPCs to maximize functionality.
We test every raw material batch using high-performance liquid chromatography (HPLC) for raw monomer counts and UV-Vis spectrophotometry for total proanthocyanidin content. We run strict checks for heavy metals (Pb, As, Hg, Cd), pesticide residues, and residual solvents to guarantee full compliance with USP, EP, and FDA standards.
We primarily extract proanthocyanidins from Grape Seed (Vitis vinifera), French Maritime Pine Bark (Pinus pinaster), and Cranberries (Vaccinium macrocarpon). Each source delivers a distinct phytochemical profile optimized for specific dietary supplement or cosmetic formulations.
Our standardized plant extracts have a shelf life of 24 months from the production date. They should be stored in their original sealed packaging in a cool, dry area away from direct sunlight, moisture, and high temperatures to prevent active compound oxidation.
Yes. We offer custom manufacturing options to adjust mesh size, bulk density, and solubility. We can adjust extraction metrics to meet water solubility targets for ready-to-mix beverage powders or optimize powder flowability for high-speed capsule filling.
