This fine brown-yellow powder provides a strong alpha-glucosidase inhibition for postprandial glucose management. We have a direct connection to the certified planting base, such that pesticide residues are less than 0.01mg/kg, with our whole chain traceability system. We guarantee batch to batch consistency with moisture content ≤5% and heavy metals ≤10ppm with ISO 22000, FSSC 22000, Halal and Kosher certifications.

What Is Mulberry Leaf Extract Powder?

The product is a concentrated botanical extract prepared from the leaves of Morus alba by water-alcohol extraction and vacuum spray drying. For more than 1,800 years, it has been used in traditional Chinese medicine as "sangye" to help support healthy blood sugar levels.

The powder's key bioactive constituent, 1-DNJ, naturally blocks carbohydrate-digesting enzymes. This makes it an important ingredient in functional diets aimed at metabolic wellness. You receive a clean-label alternative to pharmaceutical blood sugar regulators.”

Our extract contains many active constituents including quercetin-3-triglucoside and chlorogenic acid. Together, DNJ and these polyphenols act synergistically for glycemic management and antioxidant protection. This resulted in a multi-target solution for formulations of metabolic health.

Technical Properties & Specifications

Physical and Chemical Characteristics

The extract demonstrates great water solubility and thermal stability up to 120°C, which makes it suitable for beverage formulations and pasteurization operations. It is hygroscopic, so careful moisture management is essential during storage and handling.

The powder is of homogeneous particle size 80 mesh, suitable for tablet compression and capsule encapsulation processes. Bulk density standards keep flow rates uniform in high-speed automated production processes.

Quality Parameters

Core Manufacturing Advantages

1. Established Extraction Technology

Our production method includes normal water-alcohol extraction, stratification and decolorization. This eliminates chlorophyll and tannins but leaves heat-sensitive alkaloids like DNJ.

Three integrated concentration systems operate at vacuum conditions to prevent heat damage. The parameters of spray-drying are designed to retain the bioactivity of DNJ at levels higher than 98% of the starting values.

2. Strict Quality Control Procedures

Each batch is tested for 500+ pesticide residues by GC-MS/LC-MS to comply with EP and USP limitations. We quantify DNJ using HPLC-MS/MS detection specifically, and not unreliable UV techniques which would miss this non-chromophore molecule.

TLC fingerprinting is a tool for botanical authenticity confirmation and screening for synthetic Acarbose adulteration. In our independent laboratory we validate every certificate of analysis with HPLC, GC and UV-Vis spectrophotometers.

3. Reliability of the Supply Chain

Achieve whole-process traceability from field to finished product by direct connection with the approved planting base. We keep 100 tons of goods on hand for rapid order fulfillment.

We can manufacturer to customer requirements with a lead time of 7 to 15 days. In stock items ship within 7 days of payment confirmation. Enjoy steady pricing and dependable quality all year long.

4. Compliance & Certifications

Our facility is ISO 9001, GMP, HACCP, FSSC 22000, Halal and Kosher certified. All batches are FDA compliant and third party lab tested.

We offer free pre-shipment samples for your internal testing. We invite you to visit our plant and see our manufacturing capabilities and quality processes for yourself.

5. Flexible OEM/ODM Service

We can tailor extract ratios, DNJ concentrations and particle sizes to meet the needs of your product. Complementary botanicals or excipients may be blended to provide pre-mixes ready for encapsulation.

Our technical team provides formula optimization in tablets, capsules, drinks and functional food bars. The minimum order quantity for R&D trials is merely 1 kg.

Key Applications in Functional Nutrition

Blood Sugar Support

Mulberry Leaf Extract Powder naturally inhibits the intestinal alpha-glucosidase enzymes to decrease the digestion of carbohydrates (1-DNJ content). This leads to lower postprandial glucose increases without increasing insulin secretion.

You might manufacture stand-alone blood sugar support solutions or combine the extract with chromium, berberine or cinnamon for synergistic effects. Clinical investigations indicate dosages of 250-500 mg per serving standardized to 1-2% DNJ.

Metabolic Health Drinks

Due to its high water solubility, this extract is perfect for use in ready-to-drink teas, protein smoothies and wellness shots. Its thermal stability is resistant to pasteurization temperatures that are required for shelf-stable beverage goods.

The light brown-yellow colour and mild vegetable flavour mix well with fruit flavours. Typical utilization levels are 0.5 to 1.5% in finished beverages.

Weight Loss Formulas

Mulberry leaf extract helps you reach your calorie restriction objectives by making carbohydrates less efficient at being absorbed. It is combined with green tea extract and Garcinia cambogia to make a complete weight management product.

The antioxidant polyphenols also offer extra metabolic assistance by lowering the oxidative stress linked with obesity and insulin resistance.

Scientific Background & Bioactive Mechanisms

1-Deoxynojirimycin (DNJ) 

This imino sugar mimics the glucose structure to bind competitively the alpha-glucosidase active sites. The enzyme inhibition tests indicates IC50 values similar to pharmacological drugs like Acarbose but with superior stomach tolerance.

DNJ also affects the expression of glucose transporters in intestinal cells. This double process delivers immediate and lasting advantages on glycemia.

Flavonoid & Polyphenol Complex 

Chlorogenic acid and quercetin derivatives give a strong antioxidant action. These chemicals scavenge reactive oxygen species damaging pancreatic beta cells and interfering with insulin signalling.

Mulberry leaf polyphenols increased insulin sensitivity through activation of AMPK pathways in preclinical animals . This makes the extract useful in the prevention and control of Metabolic Syndrome.

Amino Acids & GABA

Naturally occurring gamma-aminobutyric acid helps to relax the blood vessels and is good for the heart and circulatory system. This is for the typical co-occurrence of blood sugar imbalance and high blood pressure.

Packaging & Storage

Standard Packaging: 25kg/fibre drum with double food grade PE lining

Storage: Store below 25°C in a cool, dry place protected from direct light and moisture

Shelf Life: 24 months when stored properly sealed

For smaller production runs we may offer custom packaging such as 1 kg, 5 kg and 10 kg aluminium foil bags. Nitrogen flush provided for humid climates to extend shelf life.

FAQ

Q: What is the appropriate concentration of DNJ for blood sugar support supplements?

A: Clinical study supports 1-2% DNJ standardization at 250-500 mg/serving for postprandial glucose management. Higher concentrations (3–5% DNJ) allow for lower dose capsules but require careful formulation to ensure stability.

Q: What is the difference between DNJ content verification and normal UV testing?

A: 1-DNJ does not contain a UV-absorbing chromophore, so UV spectrophotometry would not be a reliable method. Accurate quantification needs HPLC-ELSD, HPLC-MS/MS or pre-column derivatization using FMOC-Cl. Always ask suppliers for validation data.

Q. Is this extract suitable for use in hot fill applications?

A: Yeah. The product remains DNJ stable up to 120 °C for normal pasteurization cycles (30 seconds). Do not use extended exposures above 130 °C, which may impair alkaloid content.

Q: How do you test for adulteration?

A: Each batch is subjected to TLC and HPLC fingerprinting to identify synthetic Acarbose spiking which is a prevalent industry scam. We have around 50 unique Morus alba plant markers in our reference standard library.

Q: Do you allow custom extract ratios other than the default 10:1?

A: yes. We have 5:1, 20:1 and bespoke ratios depending on your required bioactive profile. Our technical team may change the extraction conditions to optimize the DNJ yield or the polyphenol content as per your requirements.

Q: What certifications do you send with each shipment?

A: Each order comes with a CoA (Certificate of Analysis) which has the HPLC chromatograms, microbiological tests, heavy metals screening and pesticide residue reports. Halal Certificate, Kosher Certificate, Organic Certificate - Available on Demand
