Lemon Bioflavonoids represent a robust group of plant-derived polyphenolic compounds isolated primarily from the peel, pulp, and juice of Citrus limon. Recognized globally for their potent antioxidant capacity and synergistic relationship with Vitamin C, these bioflavonoids—including key compounds such as Eriocitrin, Hesperidin, Rutin, and Naringin—are fast becoming vital components in premium nutraceutical, cosmetic, pharmaceutical, and animal nutrition applications.
As search intelligence demonstrates, forward-thinking health formulation developers are shifting away from generic synthetic additives toward botanical phytonutrients that deliver clear "Information Gain"—namely, documented clinical efficacy, verified traceabilities, and organic solvent-free molecular profiles. This shift has elevated the demand for dedicated Lemon Bioflavonoids Manufacturers & Factories capable of producing standardized bioactivity profiles at scale.
From cosmetic skin defense formulas to metabolic-supporting medical foods, lemon bioflavonoids present an ever-expanding commercial spectrum.
Advanced dietary supplements targeting endothelial protection, venous microcirculation support (such as chronic venous insufficiency relief), and optimal capillary strength. Standardized eriocitrin provides significant glyco-metabolic control, helping regulate healthy blood glucose levels post-meals.
Incorporated into anti-pollution serums and whitening creams. Lemon bioflavonoids effectively downregulate tyrosinase pathways, reduce UV-induced oxidative stress in cutaneous layers, and support collagen matrices by inhibiting enzyme degradation.
Acts as natural preservatives to combat lipid oxidation in high-fat foods. They also serve as clean-label functional ingredients in wellness tonics, energy formulas, and isotonic sports drinks requiring high solubility and stability under acidic conditions.
Combining agricultural dominance with high-technology extraction complexes to deliver competitive, USP/EP-compliant bioflavonoids.
China is home to the world's most consolidated botanical processing infrastructures. At Shaanxi ShineHerb Biotech Co., Ltd., we combine the localized agricultural volume of premium lemon cultivars from raw material regions with advanced molecular separation technologies in Xi'an. This proximity reduces transit degradation, preserving fragile polyphenol structures.
Our extraction facilities operate continuous counter-current extraction systems (CCE) coupled with multi-stage membrane separation. By avoiding long thermal cycles, we maintain the highest purity of eriocitrin and hesperidin, preventing heat-induced oxidation and polymerization. Our customers benefit from massive cost efficiencies, year-round supply reliability, and comprehensive physical-chemical compliance (USP, EP, CP standards).
Based in the Hi-Tech Zone of Xi'an, Shaanxi Province, Shaanxi ShineHerb Biotech Co., Ltd. has developed over two decades of robust experience in the research, development, custom manufacturing, and global exportation of elite active pharmaceutical intermediates, enzyme preparations, premium plant extracts, vitamins, amino acids, and nutraceutical raw materials.
With an established presence dating back to 2002, our scientific mission focuses on supplying verified, highly standardized ingredients that integrate seamlessly into complex finished formulations. Over the years, our primary portfolio—featuring high-demand products like Lactase, Bromelain, Pancreatin, Papain, Quercetin, N-Acetyl-L-Cysteine (NAC), PQQ, and Glucosamine Sulfate 2KCL—has achieved critical acclaim across Europe, North America, and Southeast Asia.
We work to transform natural botanical biomass into functional molecular ingredients while meeting strict regulatory standards, ensuring our global customer base receives stable, clean, and highly bioactive compounds.
Our engineering protocols guarantee molecular stability, batch-to-batch homogeneity, and verified bioactivity.
Our quality assurance protocol spans raw material harvesting parameters, multi-stage solvent extraction, membrane concentration, solvent elimination, and final analytical verification via HPLC, GC-MS, and ICP-MS for pesticide and heavy metal compliance.
We specialize in custom standardizations, adjusting bioflavonoid concentrations (10% to 90% HPLC), modifying physical parameters such as bulk density and particle size distribution (for direct compression or tableting), and delivering highly soluble, neutral-taste formulations.
Our industrial production systems comply strictly with international GMP requirements. Each production cycle is completely traceable, supported by a Certificate of Analysis (COA), Allergen Statements, GMO declarations, and heavy metal limits meeting global expectations.
Sourcing unripe, active-rich Citrus limon fruits. Peels undergo strict inspection for agricultural pesticide residues and heavy metal content before processing.
Utilizing clean water-ethanol systems. Optimized pressure and temperature matrices preserve the fragile molecular structure of eriocitrin and hesperidin.
Targeted separation of target bioflavonoid structures from crude sugars, fibers, and organic acids, boosting the active concentration from a baseline of 5% up to 90% purity.
Protects the thermal limits of the polyphenols, producing a free-flowing, fine powder (typically 80 mesh) with high water solubility and physical-chemical stability.
How localized industries implement lemon bioflavonoids to address regulatory and market needs.
Due to the prevalence of metabolic syndrome, North American brands are actively formulating lemon bioflavonoid complexes (standardized in Eriocitrin) for insulin sensitivity products, cardiovascular wellness lines, and sports nutrition brands designed to reduce post-workout inflammatory responses.
With EFSA regulations restricting synthetic chemicals like BHT and BHA, European food processing operations use highly standardized water-soluble lemon bioflavonoid powders to extend the shelf life of meats, oils, and ready-to-eat products, maintaining natural status on ingredient labels.
In highly competitive cosmetic markets in Japan, South Korea, and China, micro-encapsulated lemon bioflavonoids are used in brightening serums, anti-blue-light face creams, and under-eye treatments targeting dark circles caused by vascular congestion.
1. Nanocarrier Liposomal Delivery: Current research at ShineHerb Biotech focuses on structuring liposomal and phytosomal nano-emulsions of Lemon Bioflavonoids to double intestinal absorption rates and extend circulatory half-life.
2. Circular Agriculture: Zero-waste extraction methodologies that fully utilize citrus pulp and peel biomass to produce valuable dietary fibers and essential oils alongside bioactive flavonoids, reducing environmental impacts.

Answers to common chemical, logistics, and quality assurance questions from formulation scientists and procurement managers.
We provide standardized options ranging from 10% to 90% bioflavonoids measured via UV-Vis, or standardized for specific active marker compounds, such as 10% to 50% Eriocitrin or Hesperidin by HPLC. This flexibility allows formulators to customize product potency.
We operate in compliance with the USP <561> pesticide limits and EC 396/2005 standards. Every raw harvest batch undergoes GC-MS/MS testing for over 400 pesticide residues, ensuring compliance in the North American and European Union markets.
Standard citrus extracts have limited solubility. However, our specialized eriocitrin-rich lemon extract utilizes a modified filtration process that yields a highly water-soluble powder, suitable for clean-label functional beverages and RTD formulas without precipitation.
Our powders have a standard shelf-life of 24 months from the date of manufacture. They should be stored in original, unopened packaging in a cool, dry location away from direct sunlight and humidity.
We test every production run using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to confirm that Lead is below 0.5 ppm, Arsenic is below 0.5 ppm, Cadmium is below 0.1 ppm, and Mercury is below 0.1 ppm, complying with global food safety standards.
For standardized stock powders, our MOQ starts at 25kg (one fiber drum). For custom bioactivity standardizations or specific particle size adjustments, our MOQ typically ranges from 100kg to 500kg, depending on the synthesis parameters.
