Ellagic Acid 98%

Ellagic Acid Pomegranate Extract is a premium product that is extracted from natural sources. Ellagic acid exists in both free and combined forms in nature, such as ellagitannin, glycoside, etc. Ellagic acid has been linked with numerous health benefits, making it an excellent addition to your personal care products.

Ellagic acid (EA) is a natural polyphenolic compound that is a product of the hydrolysis of ellagitannins. It is particularly abundant in pomegranate, strawberry, raspberry, walnut, and walnut. Among them, pomegranate (Punica granatum L.) is recognized as one of the highest quality commercial sources of Ellagic Acid and its precursor, Ellagitannins. Its skin, juice, seeds, and flowers all contain high concentrations of such active ingredients._[1]
Pomegranate, as a long-standing "super fruit", owes much of its health value to its rich polyphenols. Ellagic Acid, as the core functional molecule, exhibits excellent antioxidant activity due to its unique chemical structure of four hydroxyl groups and two lactone rings. It can effectively eliminate free radicals in the body and protect cells from oxidative stress damage.

The preparation of industrial-grade high-purity tannic acid powder is a precision process involving multiple steps and intensive technology. The core goal is to efficiently obtain the target product from pomegranate by-products (such as skins) rich in tannic acid tannins through hydrolysis, extraction, separation, and purification. In recent years (2020-2024), research has focused on developing more environmentally friendly, efficient, and scalable production processes.

4.1 Raw material pretreatment

The production process begins with the by-products of pomegranate processing, primarily pomegranate peel, as it has the highest content of tannic acid. Fresh pomegranate peel is cleaned, dried (usually using hot air drying or freeze-drying to maximize the retention of active ingredients), and then crushed into a suitable particle size powder.

4.2 Extraction and hydrolysis

This step is the core of the entire process. Traditional methods primarily rely on organic solvent extraction, accompanied by acid or alkali-catalyzed hydrolysis processes, to decompose large molecules of tannic acid into smaller acids. Among them, a 70% ethanol aqueous solution is widely used in industrial production due to its high extraction efficiency and relatively low toxicity._[2]

4.3 Purification and Refinement

The crude extract obtained from the extraction is a complex mixture containing various components such as tannic acid, pigments, sugars, and organic acids. It must undergo purification steps (centrifugation, filtration, and extraction) to obtain high-quality products. The purified tannic acid solution is concentrated, crystallized, washed, and vacuum-dried to obtain high-purity tannic acid powder products that are off white or light yellow in color.

Product efficacy and mechanism of action

The health benefits of Ellagic Acid stem from its diverse biological activities, and its mechanism of action involves multiple cellular signaling pathways and molecular targets, collectively constituting its protective effect on the human body.

Strong antioxidant effect

The multiple phenolic hydroxyl groups on its molecular structure make it an excellent electron donor, capable of directly clearing various ROS and RNS. In addition, it can indirectly enhance the body's antioxidant capacity by activating the endogenous antioxidant defense system of cells and upregulating the expression of antioxidant enzymes.

Anti-inflammatory effect

Ellagic Acid can exert anti-inflammatory effects by inhibiting key pro-inflammatory signaling pathways (NF-κB). It can prevent the activation and nuclear translocation of NF-κB, thereby downregulating the production of downstream inflammatory mediators, including TNF-α, IL-6, and cyclooxygenase-2 (COX-2).

Skin Health and Beauty

Research has shown that Ellagic Acid can inhibit the activity of tyrosinase, suppress melanin synthesis, and has the potential to whiten and lighten spots.

Meanwhile, its antioxidant properties help protect skin collagen from UV-induced degradation and help prevent photoaging.

Cardiovascular Health Support

Ellagic Acid can protect the cardiovascular system in many ways, including lowering blood pressure, improving vascular endothelial function, and reducing atherosclerosis. Its antioxidant and anti-inflammatory properties help minimize damage to the blood vessel wall and plaque formation.

Although Ellagic Acid has significant in vitro biological activity, its bioavailability in the human body is a complex and challenging topic. 

• The challenge of low bioavailability: Pure Ellagic Acid has poor water solubility and a flat molecular structure that is easy to aggregate, resulting in low dissolution and absorption efficiency in the gastrointestinal tract. Multiple human studies have shown that after oral administration of pomegranate juice or pomegranate extract, the concentration of the prototype ellagic acid detected in plasma is very low._[3] 

Research data shows that after ingestion of Ellagic Acid, the concentration of Ellagic Acid in plasma typically reaches its peak around 1 hour._[4]  Different dosage forms (e.g., juice or extract powder) can influence absorption rate, leading to variations in Tmax ranging from 0.65 to 2.58 hours._[3]

With its clear health benefits and natural source advantages, Ellagic Acid powder derived from pomegranate has a wide range of applications in the dietary supplement market.
