Efficacy & Application Fields

Efficacy

1. Powerful antioxidant: scavenge free radicals, reduce oxidative stress damage.
2. Support vascular health: improve endothelial function, promote blood vessel relaxation.
3. Ant‑inflammatory effect: inhibit inflammatory mediator release.
4. Skin‑care related: resist oxidative aging, protect skin from external stimulus damage.

Application Fields

1. Dietary Supplement: Capsules, tablets, powder blends for cardiovascular‑support formulas.
2. Cosmetics & Personal Care: Anti‑aging serums, creams, antioxidant skincare raw material.
3. Functional Food & Beverage: Antioxidant functional drinks, health food raw materials.
4. Pharmaceutical intermediate: For research‑grade formula development.

Product Advantages

1. High‑purity monomer: 98% Epicatechin detected by HPLC, low miscellaneous catechin impurity, strictly separate from EGCG, caffeine. Batch‑to‑batch consistency guaranteed.
2. Natural botanical origin: Isolated from green tea leaves, no chemical synthetic route, non‑GMO, no artificial preservatives or excipients added.
3. Low‑temperature whole‑process production: Strictly control temperature in extraction, concentration and drying steps, effectively prevent epicatechin oxidation and degradation.
4. Complete quality assurance system: Manufactured under cGMP workshop; comply with ISO9001, ISO22000, HACCP. Each batch supplied with full set COA, HPLC spectrogram, MSDS.
5. Customization available: Support customized purity, particle size and bulk packaging; support small trial order and mass production.
6. Good processing performance: Low hygroscopicity, stable powder status; suitable for tablet pressing, capsule filling and cosmetic raw‑material compounding.

Stability & Compatibility

1. Thermal stability: Stable under ≤60 ℃; high temperature for long time will accelerate oxidation and color deepening.
2. pH sensitivity: More stable under acidic condition; easy to turn yellow and degrade under alkaline environment.
3. Light sensitivity: Strong light will trigger oxidation reaction; must store away from light.
4. Compatibility: Compatible with most neutral and acidic plant extracts; avoid mixing with strong oxidizing agents.
5. Hygroscopicity: Low hygroscopicity, but long‑term exposure to humid air will affect product appearance.

Epicatechin (EC) Production Process Flow

1. Raw Material Pre‑treatment Select premium green tea leaves (Camellia sinensis). Remove foreign impurities. Pre‑screen raw materials for heavy metals and pesticide residues. Crush and sieve to proper particle size for extraction. Non‑GMO botanical feedstock.

2. Low‑temperature Counter‑current Extraction Adopt food‑grade ethanol‑water solvent system. Multi‑stage counter‑current solid‑liquid extraction. Strictly control extraction temperature below 55 ℃ to prevent epicatechin thermal oxidation and degradation. Obtain crude tea polyphenol extracting solution.

3. Solid‑liquid Separation & Filtration Filter press to remove tea leaf residues. Multi‑stage precision filtration to eliminate suspended solids, plant fibers and macromolecular impurities. Gain clear crude extract liquid.

4. Vacuum Low‑temperature Concentration Vacuum negative‑pressure concentration, temperature ≤55 ℃. Recycle ethanol solvent. Concentrate liquid to obtain tea polyphenol concentrate. Avoid high‑temperature damage to epicatechin monomer.

5. Macroporous Resin Adsorption & Desorption Purification Load concentrate onto macroporous adsorption resin. Adsorb target catechin components; wash away caffeine, saccharides, chlorophyll and water‑soluble miscellaneous impurities. Elute with ethanol solution to collect epicatechin‑rich eluent.

6. Preparative Column Chromatography Refinement Further chromatographic separation. Separate epicatechin from EGCG, epigallocatechin and other catechin analogues. Effectively remove isomer impurities to upgrade monomer purity.

7. Nanofiltration Desalting & Impurity Removal Nanofiltration membrane treatment. Remove inorganic salts, monosaccharides and small‑polar miscellaneous substances. Reduce ash content of feed liquid.

8. Solvent Recovery & Liquid Concentration Secondary vacuum concentration, recover residual ethanol. Get high‑purity epicatechin aqueous concentrate.

9. Low‑temperature Vacuum Drying Vacuum drying with temperature controlled ≤60 ℃. Prevent oxidation under thermal condition. Obtain crude dry solid.

10. Crushing & Sifting Crush dried material, sieve through 80‑mesh screen. Uniform fine powder is obtained.

11. Full‑batch Quality Testing Test items: appearance, HPLC purity, loss on drying, residue on ignition, heavy metals, pesticide residues, residual solvents, microbiological indicators. Generate batch COA and HPLC chromatogram.

12. Aseptic Packaging Operate in clean‑room environment. Double‑layer food‑grade inner bag + aluminum foil vacuum sealing. Pack into cardboard drum. Label batch number, production date, shelf‑life and storage instruction.
