Hovenia Dulcis Extract Powder

Hovenia Dulcis Extract powder  is a natural product derived from the dried mature seeds of Hovenia dulcis Thunb., a plant belonging to the Rhamnaceae family. This extract typically presents as a fine, brown-yellow to brownish powder and is rich in bioactive compounds. Key components include dihydromyricetin (DHM), a primary active ingredient known for its hepatoprotective and anti-hangover properties. It also contains various flavonoids such as kaempferol, apigenin, myricetin, and quercetin, as well as saponins and other beneficial compounds like emodin.Traditionally, Hovenia dulcis has been used in Chinese medicine for its properties in nourishing Yin, promoting fluid production, replenishing Qi, and detoxification.
This extract finds applications in health supplements, functional food additives, and potentially in the development of pharmaceuticals. Common specifications include DHM 1%~30% by HPLC, and total flavonoid 7.0%.
Jiuyuan Biotech Hovenia Dulcis Extract Powder is developed for buyers who need a clear, auditable raw-material brief rather than an opaque commodity powder. We begin with botanical identity and defined plant material, then align extraction, drying, particle profile, analytical testing, and documents with the intended formulation and target market.

Raw material selection:

Hovenia dulcis should comply with the provisions of GB 19300 to ensure the quality and safety of the raw materials.

Extraction process:

Water extraction method: The best extraction conditions are 100℃, solid-liquid ratio 1 g:8 mL, heating for 0.5 h, and reflux extraction for 3 times.

Alcohol extraction method: The best extraction conditions are 80℃, solid-liquid ratio 1 g:6 mL, heating for 1.5 h, and reflux extraction with 50% volume fraction ethanol for 3 times.

Acid extraction method: The best extraction conditions are temperature 90℃, solid-liquid ratio 1:100 (g: mL), time 2.5 h, and hydrochloric acid concentration 0.2 mol/L.

Refining treatment:

The extract should be refined to remove impurities and pigments. The best refining conditions are adding 0.5% activated carbon, a stirring time of 30 minutes, adding 0.5% polyvinyl alcohol after filtration, and a stirring time of 30 minutes.

Drying process:

Use spray drying process, air inlet temperature 160-180℃, air outlet temperature 70-90℃.

Quality control:

The product should meet relevant quality standards, including sensory requirements, physical and chemical indicators, and microbiological indicators. The sensory requirements should be powdery, light yellow to brown, with its special smell.

Potential for Alcohol Metabolism Support:

In vitro and animal studies suggest that Hovenia dulcis extract may modulate ethanol absorption in the digestive tract and influence the rate at which ethanol enters systemic circulation. Furthermore, its water extract has demonstrated the capacity to enhance alcohol dehydrogenase activity in preclinical models, indicating a potential role in promoting alcohol metabolism.

Potential Hepatoprotective Properties:

Preclinical research indicates that the extract may interfere with the progression of liver fibrosis and support hepatocyte repair and regeneration. Studies have shown a potential to attenuate the elevation of alanine transaminase (ALT) and aspartate transaminase (AST) induced by ethanol and lipopolysaccharide (LPS). Additionally, it may offer protection against ethanol-induced hepatic lipid peroxidation and potentially delay or prevent the development of fatty liver in animal models. In vitro studies suggest a growth-promoting effect on hepatocytes and an ability to enhance their survival and proliferation rates.

Potential Anti-Fatigue Effects:

Some animal studies suggest that the extract may possess anti-fatigue properties, potentially by increasing glycogen storage and reducing post-exercise urea nitrogen accumulation.

Potential Anti-Aging Effects:

Research in animal models of aging indicates that the extract may improve learning and memory deficits associated with D-galactose-induced subacute aging. These effects may be linked to an observed increase in antioxidant enzyme activity, a reduction in lipid peroxide production, and an overall enhancement of antioxidant capacity in these models.

Potential Physical Performance Enhancement:

Animal studies have shown that the extract may improve tolerance to cold and heat stress and extend swimming and climbing time in mice, suggesting a potential to enhance overall physical endurance in these models.

Potential Diuretic and Anti-Edema Effects:

The extract has demonstrated a significant diuretic effect in preclinical studies, promoting urine excretion and potentially aiding in the elimination of excess bodily fluid, which may contribute to the reduction of edema.

Hovenia Dulcis Extract Powder can be evaluated for several dosage-form formats. Formulators should conduct compatibility, sensory, stability, and regulatory assessments on the final recipe.

Formulation reality check

Natural extracts can contribute color, aroma, and astringency. A laboratory sample may perform differently in a flavored, sweetened, mineral-rich, or protein-containing finished formula. Pilot-scale testing is the sensible bridge between sample approval and commercial production.

3. Target specification
Indicate whether you need a ratio extract, a marker-standardized grade, or a non-standardized whole-spectrum extract.

4. Dosage format and annual volume
Capsules, tablets, powders, and beverages place different demands on particle size, taste, and bulk density.

5. Testing package
Identify required limits for heavy metals, microbiology, pesticide residues, residual solvents, and allergens.

Red flags worth investigating

● A supplier cannot state the plant part used.

● A high assay is claimed without an analytical method.

● The COA is generic, undated, or not linked to a batch.

● "Organic," "GMP," or "standardized" is claimed without a valid certificate or specification.

● The supplier makes disease-treatment claims for a food or supplement ingredient.

The reliable path is pleasantly unglamorous: verify the material, verify the method, and verify the paperwork.

1. What is Hovenia Dulcis Extract Powder?

It is a powdered botanical extract derived from Hovenia dulcis Thunb., commonly known as Japanese raisin tree. The precise composition depends on the plant part and extraction process used.

2. Is Hovenia dulcis the same as dihydromyricetin?

No. Hovenia dulcis is the botanical source plant; dihydromyricetin is one compound reported in certain Hovenia-derived materials. The presence and level of any marker must be confirmed by the specific product COA and analytical method.

3. Which plant part should be stated on the specification?

The plant part must be stated exactly as used-such as fruit, fruit peduncle, or an agreed blend. This matters because plant part can influence the extract's phytochemical profile and analytical result.

4. Can this ingredient be used in dietary supplements?

It may be considered for dietary supplement formulation, subject to the laws, novel-food status, permitted use conditions, and labeling rules of the target market. The importer or brand owner should obtain market-specific regulatory advice before commercialization.

5. What documents can be provided for supplier qualification?

A typical package may include COA, TDS, SDS, specification sheet, allergen statement, GMO statement, and relevant certificates. Availability depends on the final grade and commercial agreement.

6. Can Jiuyuan Biotech provide a standardized grade?

Standardized options can be discussed based on the requested marker, target assay, method, plant part, and order volume. A feasible specification should be confirmed with technical review before contracting.

7. How should the powder be stored?

Store the material in a cool, dry place, protected from direct light and moisture, in tightly closed original packaging. The final storage statement and shelf-life period should be taken from the product-specific specification and COA.

8. Why should we request a batch-specific COA?

A batch-specific COA helps confirm that the actual shipped lot-not merely a representative sample-meets the agreed quality requirements. This is especially important for botanicals, where natural variation is expected.

Jiuyuan Biotech supplies Hovenia Dulcis Extract Powder to food manufacturers, supplement brands, and contract formulators across North America, Europe, and the Asia-Pacific region. Our technical team - not a generic sales inbox - handles every inquiry.
