What Is Ellagic Acid Powder?
Ellagic acid (chemical formula C₁₄H₆O₈) is a naturally occurring polyphenolic compound classified as a dilactone dimer of gallic acid. This plant-derived antioxidant belongs to the broader family of hydrolyzable tannins and is abundantly present in the tissues of soft fruits, nuts, and certain botanical sources — most notably pomegranate rind (Punica granatum), raspberries, blackberries, walnuts, and pecans.
As a high-value phytochemical, ellagic acid powder has attracted sustained interest from the nutraceutical, functional food, dietary supplement, and cosmetics industries. Its robust free radical scavenging capacity, documented biological activities, and compatibility with a wide range of formulations make it a sought-after raw material for B2B buyers, brand developers, contract manufacturers, and ingredient distributors worldwide.
The Extract Factory specializes in the production and global supply of ellagic acid powder derived from pomegranate peel extract, offering assay grades of 40% and 90% to meet diverse formulation requirements. With over six years of dedicated manufacturing experience and nearly a decade of expertise in the plant extract sector, we deliver a consistent, traceable, and food-grade product backed by rigorous quality control.

Source, Extraction & Manufacturing Process
Botanical Origin
The ellagic acid powder supplied by The Extract Factory is primarily derived from the dried peel (rind) of pomegranate fruit (Punica granatum L.). Pomegranate peel is a well-documented, commercially viable source rich in ellagitannins — the precursor compounds that hydrolyze to yield free ellagic acid during processing. The use of pomegranate rind also aligns with sustainable sourcing practices, as it represents an underutilized by-product of the juice and fresh fruit industry.
Extraction Methodology
The manufacturing process typically involves the following stages:
- Raw Material Preparation — Dried pomegranate peel is milled to an appropriate particle size to maximize surface area for extraction.
- Solvent Extraction — Aqueous or hydro-ethanolic solvent systems are employed under controlled temperature and time parameters to extract ellagitannins efficiently.
- Hydrolysis — The extracted ellagitannins undergo acid or enzymatic hydrolysis to release free ellagic acid.
- Purification & Concentration — The crude extract is filtered, concentrated, and further purified to achieve the target assay (40% or 90%).
- Drying & Milling — The purified ellagic acid is spray-dried or vacuum-dried and milled into a fine, uniform powder.
- Quality Control & Packaging — Finished product undergoes comprehensive testing before being sealed in food-grade packaging.
This controlled, multi-stage process ensures batch-to-batch consistency — a critical factor for formulators and brand owners who require predictable performance in their end products.

Key Functions & Biological Activities
1. Potent Antioxidant Activity
Since the mid-20th century, researchers have extensively investigated the antioxidant properties of ellagic acid in both in vitro and in vivo models. The compound demonstrates strong scavenging activity against oxygen free radicals and hydroxyl radicals — mechanisms that have been shown to exceed those of comparable antioxidants such as sesamol, olive leaf extract polyphenols, and lutein in certain assay systems.
Free Radical Scavenging:
Ellagic acid neutralizes reactive oxygen species (ROS) through direct electron donation, helping to protect cellular membranes, proteins, and nucleic acids from oxidative damage. This activity is particularly relevant for nutraceutical products targeting oxidative stress management.
Inhibition of Lipid Peroxidation:
Ellagic acid is recognized as one of the most effective inhibitors of NADPH-dependent lipid peroxidation initiation in microsomal systems. Studies have demonstrated its ability to strongly suppress doxorubicin-induced lipid peroxidation and to inhibit myoglobin/hydrogen peroxide-dependent lipid peroxidation cascades. By preventing the formation of lipid peroxides (LPO) and reducing ROS generation, ellagic acid contributes to cellular protection against cytotoxic insults — a property of interest to supplement and functional food developers.
Protection Against Nitrosative Damage:
In vitro research indicates that ellagic acid powder can mitigate cell damage caused by radiation, hydrogen peroxide, and mitomycin C in murine bone marrow cell models. It effectively inhibits peroxynitrite-induced oxidation of DCFH (dichlorofluorescein) and prevents peroxynitrite-mediated single-strand DNA breaks in plasmid models, as well as tyrosine nitration in serum proteins. These findings underscore its role in shielding biomolecules from nitrosative and oxidative stress.
2. Anti-Inflammatory & Cellular Modulation
Ellagic acid has demonstrated the ability to modulate key inflammatory pathways. Research suggests it inhibits interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α)-induced activator protein-1 (AP-1) and mitogen-activated protein kinase (MAPK) activity. This mechanism is relevant in the context of pancreatic fibrosis and acute pancreatitis models, where pancreatic stellate cell activation plays a central role.
Additionally, as a plant secondary metabolite, ellagic acid has shown anti-eosinophilic effects in β-glucan peritonitis models, suggesting potential applications in managing allergic inflammatory responses.
3. Hepatoprotective Potential
Both in vivo and in vitro studies have indicated that ellagic acid can protect hepatocytes from carbon tetrachloride (CCl₄)-induced liver injury and counteract lipid peroxidation triggered by tert-butyl hydrogen peroxide. These properties add to its appeal for liver-support supplement formulations.
4. Tyrosinase Inhibition & Skin-Brightening Function
Melanin biosynthesis in the epidermis begins with the enzymatic conversion of tyrosine to DOPA and subsequently to DOPAquinone via tyrosinase, ultimately forming melanin pigments. Ellagic acid interferes with this pathway by inhibiting tyrosinase activity, thereby reducing melanin production. This mechanism is widely leveraged in cosmetic and skin-care product development for brightening and even-tone formulations.
Industry Applications
Ellagic acid powder's multifunctional profile makes it a versatile ingredient across several high-growth sectors:
| Industry | Application Examples |
|---|---|
| Nutraceuticals & Dietary Supplements | Antioxidant capsules, anti-aging formulas, liver support blends, immune health products |
| Functional Foods & Beverages | Fortified beverages, snack bars, powder drink mixes targeting oxidative stress reduction |
| Cosmetics & Personal Care | Skin-brightening serums, anti-aging creams, suncare formulations, depigmentation products |
| Pharmaceutical Excipients & R&D | Active pharmaceutical ingredient (API) research, formulation development, preclinical studies |
| Animal Nutrition | Antioxidant feed additives for livestock and aquaculture health management |
The 40% assay grade is well-suited for general nutraceutical and food-grade applications where moderate ellagic acid concentration is desired, while the 90% high-purity grade targets premium supplements, clinical-grade research materials, and concentrated cosmetic actives.
