Explore our core plant extracts, nutritional bio-enzymes, and cosmetic raw materials for global distribution.
Pine Bark Extract (derived from Pinus massoniana or Pinus pinaster) represents one of the most potent natural free radical scavengers recognized by contemporary biogerontology and sports physiology. Standardized to contain up to 95% Oligomeric Proanthocyanidins (OPCs), our extract exhibits an antioxidant capacity 20 times greater than Vitamin C and 50 times greater than Vitamin E. This raw material operates as a core compound in modern therapeutic formulations designed to address cardiovascular health, venous insufficiency, dermatological collagen protection, and cognitive longevity.
As a leading manufacturer, Shaanxi ShineHerb Biotech Co., Ltd. guarantees strict standardization parameters. Our production processes preserve the delicate balance of naturally occurring monomeric catechins, taxifolin, and phenolic acids. By avoiding aggressive thermal treatments and high-toxicity solvent loops, we secure a raw powder that exhibits superior bio-solubility, minimal ash content, and complete tracking transparency from raw pine forests to final vacuum-sealed drums.
How we achieve standard-setting purity of 95% Oligomeric Proanthocyanidins (OPCs) under GMP environments.
Our facility utilizes low-temperature counter-current extraction systems coupled with food-grade aqueous ethanol solutions. By dynamically monitoring pressure, flow speed, and solvent-to-solid ratios, we prevent the thermal degradation of monomeric and oligomeric polyphenols.
Key Control Metric: Zero chlorinated solvent exposure; heavy metal concentration (Pb, As, Hg, Cd) consistently maintained under 1.0 ppm; residual solvents are kept strictly below USP limits.
Sustainable harvesting of Pinus massoniana bark from certified ecological reserves. Microscopic verification and HPLC profiling ensure zero substitution errors.
Dynamic vacuum extraction operates below 50°C. This targeted range selectively dissolves active low-molecular-weight OPCs while limiting excessive high-molecular tannins.
Elution control yields customized specifications (80% - 95% OPCs) via precision chromatography, separating functional phenolics from inert plant fibers.
Instantaneous moisture evaporation yields a free-flowing, high-density powder with optimal particle distribution (80 mesh), ready for direct capsule compression.
Verify the precise physical and chemical metrics designed for pharmaceutical, supplement, and cosmetic grade formulations.

Situated in the Hi-Tech Zone of Xi'an, Shaanxi Province, Shaanxi ShineHerb Biotech Co., Ltd. benefits from the world's most concentrated plant extraction industrial cluster. This localization provides direct access to premier botanical raw materials, leading academic research facilities, and integrated logistics infrastructure. Our plant raw material sourcing relies on long-term forestry preservation partnerships, insulation from raw material scarcity, and insulation from volatile market price hikes.
Our production facilities maintain massive inventory stocks of key extracts and enzymes, allowing us to absorb market fluctuations and offer stable, year-round contract pricing to our international B2B partners. This raw-material security is coupled with immediate access to China’s massive rail network (Chang'an China-Europe Express Train) and direct air freight hubs, minimizing shipping transit windows to North America, Europe, and the Middle East.
Uninterrupted bulk supply guarantees and price protection plans for long-term contract partners.
Immediate local regulatory clearance, automated warehousing, and rapid validation loops.
How top-tier international brands integrate Pine Bark Extract into their flagship product lines.
OPCs stimulate the synthesis of endothelial nitric oxide synthase (eNOS), promoting vasodilation, microcirculation, and systemic endothelial wellness. Widely utilized in functional heart health formulations and blood pressure regulation supplements.
Pine Bark Extract binds directly to collagen and elastin, protecting matrix proteins from enzymatic degradation. It clinical reduces UV-induced hyperpigmentation, shields dermal tissues from photoaging, and supports cellular hydration.
By amplifying oxygenation kinetics and vascular blood flow, our extract accelerates waste metabolite clearance (lactic acid) from muscle tissue, mitigating delayed onset muscle soreness (DOMS) and extending peak athletic output.
Our materials conform to rigorous regulatory frameworks for importation into the US, European Union, and Asia-Pacific markets.
