Galla Chinensis, also known as Chinese Gall or *Wu Bei Zi*, is a highly valued natural commodity derived from the galls formed on the leaves of *Rhus chinensis* Mill. by the gall aphid *Melaphis chinensis* (Bell) Baker. From a phytochemical perspective, Galla Chinensis represents one of nature’s richest resources for hydrolyzable tannins, particularly gallotannins. These compound families break down into Tannic Acid, Gallic Acid, and Ellagic Acid under controlled extraction and hydrolysis protocols.
As a premier manufacturer and supplier, Andy Biotech utilizes optimized processing methodologies to ensure the high bioactivity and chemical purity of these extracts. The therapeutic and industrial benefits of Galla Chinensis extract stem from its powerful interaction with biological proteins, enzymatic inhibition capacities, and high redox potential.
| Active Component | Typical Assay Specs | Primary Biological Mechanism | Key Industrial Applications |
|---|---|---|---|
| Tannic Acid (Industrial & Food Grade) | 80% - 95% (UV-Vis / Gravimetric) | Precipitates bacterial proteins; robust metal ion chelation. | Animal health feed additives, food clarifiers, leather tanning, metal rust prevention. |
| Gallic Acid (Anhydrous/Monohydrate) | 98% - 99% (HPLC) | Scavenges free radicals; blocks NF-κB and pro-inflammatory signaling pathways. | Pharmaceutical synthesis, API intermediates, chemical antioxidant manufacturing. |
| Methyl Gallate | 90% - 98% (HPLC) | Induces apoptosis in aberrant cellular environments; exhibits strong anti-biofilm properties. | Advanced dental hygiene formulas, therapeutic research, oncology research reagents. |
| Ellagic Acid | 40% - 90% (HPLC) | Inhibits intracellular melanin synthesis by downregulating tyrosinase activity. | Dermatological treatments, premium cosmetic whitening creams, cellular aging supplements. |
Understanding the biological and chemical mechanisms that make this extract an indispensable ingredient for global brands.
The high tannin concentration in Galla Chinensis extract disrupts bacterial outer membranes and precipitates essential proteins, leading to cell lysis. Studies show it effectively inhibits *Streptococcus mutans*, *Porphyromonas gingivalis*, and *Escherichia coli*. Its unique ability to prevent biofilm formation makes it a key candidate for oral health, wound care, and natural preservation formulas.
Unlike traditional synthetic antimicrobials, Galla Chinensis extract works synergistically with fluoride to promote dental enamel remineralization. By inhibiting the dental plaque bacteria that produce organic acids, it maintains physiological pH balances, protects teeth from acid demineralization, and helps treat dentin hypersensitivity.
For animal nutrition and gastrointestinal therapeutics, the astringent property of gallotannins is highly valuable. The extract binds to mucosal proteins in the gut, forming a protective, anti-inflammatory layer. This reduces fluid loss and controls diarrhea, making it an excellent replacement for antibiotic growth promoters (AGPs) in livestock feed.
The Gallic Acid and Ellagic Acid molecules derived from Galla Chinensis are potent tyrosinase inhibitors. By blocking the enzymatic pathway that converts tyrosine into melanin, the extract effectively reduces hyperpigmentation, age spots, and UV-induced skin damage. This makes it a preferred ingredient for clean-label, plant-based cosmetic products.
Packed with phenolic hydroxyl groups, the extract is an excellent hydrogen donor. It neutralizes reactive oxygen species (ROS), prevents lipid peroxidation in food matrices, and protects mammalian cells from oxidative stress. This makes it highly sought after as a natural food preservative and anti-aging supplement ingredient.
By modulating MAPKs and NF-κB signaling pathways, Galla Chinensis extract reduces the release of pro-inflammatory cytokines like TNF-α and IL-6. This systemic regulation helps mitigate chronic inflammatory conditions in both human wellness applications and veterinary medicine.
At Andy Biotech, our production technology bridges traditional extraction with advanced chemical engineering. Standard extract manufacturing often suffers from batch-to-batch variations and high heavy-metal risk due to poor raw material control. Our advanced manufacturing system overcomes these issues through a multi-stage process:
We use customized water-based extraction and supercritical CO2 processes. This avoids chemical solvent residues (such as methanol or acetone) in the final product, achieving a clean-label profile suitable for functional foods and pharmaceuticals.
Using ultrafiltration and nanofiltration membranes, we isolate specific molecular-weight tannins. This allows us to separate bitter-tasting, heavy molecules from light, highly bioavailable gallotannins, optimizing the extract's taste and solubility.
Using proprietary food-grade enzymatic hydrolysis, we convert complex gallotannins into high-purity Gallic Acid and Ellagic Acid. This process increases active compound yields by up to 35% compared to traditional acid-base hydrolysis.
Our low-temperature spray drying technology prevents thermal degradation of polyphenol structures. This ensures the powder dissolves instantly and remains stable in liquid formulations.
As a global B2B supplier, we provide tailored formulations to meet the specific demands of diverse industries:
With global bans on antibiotic growth promoters, our Galla Chinensis extract (rich in Tannic Acid) offers a proven alternative. It improves fecal consistency, balances gut microbiota, and boosts growth performance in swine, poultry, and aquaculture.
We supply high-purity Gallic Acid and Ellagic Acid to international cosmetic brands. Our products are optimized for stability in skin-brightening serums, anti-pollution creams, and natural anti-acne formulations.
Replacing synthetic preservatives like BHA and BHT is a major industry challenge. Our food-grade Galla Chinensis extract prevents fat oxidation in meats, oils, and baked goods, significantly extending shelf life without altering the product's sensory profile.

Andy was born in a small village close to the Hanjiang River in Hanzhong, Shaanxi province, China. Thirty years ago, when she was still a little child, she caught a cold, but medical services were not available unless the family crossed over high mountains to find a hospital. Thus, Andy's grandfather first used Echinacea leaves soaked in water for her treatment, then he dug Echinacea root and shredded it into pulp, squeezing the liquid for Andy to drink one spoon every two hours. Andy recovered after this treatment.
As a child, Andy watched her grandfather harness the healing power of plants in his humble garden. His ancient herbal remedies were not just treatments; they were magic. That early wonder blossomed into a profound passion for plant extracts and a deep respect for nature’s wisdom. From that time on, little Andy swore that she would help to spread herbs all over the world to benefit more people.
This personal journey is the heart of Andy Biotech. It’s why Andy Biotech is dedicated to researching and delivering the purest, most effective botanical solutions for modern wellness. Andy’s lifelong vow is to honor that tradition by innovating for a healthier future, empowering lives through the timeless power of plants.
