What Is DNJ Mulberry Leaf Extract?
DNJ (1-Deoxynojirimycin) mulberry leaf extract is a specialized botanical extract derived from Morus species, particularly Morus alba, which is rich in bioactive compounds that inhibit alpha-glucosidase—an enzyme responsible for carbohydrate digestion. By slowing glucose absorption, DNJ helps moderate blood sugar spikes after meals, making it a valuable ingredient for functional foods, dietary supplements, and nutraceutical formulations.
Scientific Extraction & Fermentation Process
To enhance DNJ concentration, our extraction process incorporates fermentation optimization using select microbial strains. Research indicates that Ganoderma lucidum significantly boosts DNJ yield in mulberry leaves compared to other fermentation agents.
Our high-performance liquid chromatography (HPLC-FD) with fluorescence detection ensures precise quantification of DNJ, guaranteeing consistent potency and purity in every batch.

Key Benefits & Applications of DNJ Mulberry Leaf Extract
1. Blood Sugar Management
As a natural alpha-glucosidase inhibitor, DNJ mulberry leaf extract helps reduce postprandial hyperglycemia by slowing carbohydrate digestion, making it ideal for:
- Diabetic-friendly supplements
- Glucose-supportive functional foods
- Weight management formulations
2. Cardiovascular Support
Studies suggest that long-term consumption of mulberry leaf extract may:
- Lower blood pressure and heart rate
- Inhibit LDL ("bad" cholesterol) oxidation
- Reduce atherosclerosis risk by preventing plaque buildup in arteries
3. Skin Health & Brightening
DNJ mulberry leaf extract exhibits anti-tyrosinase activity, which:
- Inhibits melanin production, promoting a brighter, more even skin tone
- Supports acne-prone skin due to its antimicrobial and anti-inflammatory properties
- Enhances digestive health when used in enzyme-based supplements
4. Neuroprotective Effects
Bioactive compounds in mulberry leaves, such as kaempferol-3-O-glucoside and kaempferol-3-O-(6-malonyl) glucoside, have been shown to:
- Inhibit beta-amyloid protein formation
- Potentially slow cognitive decline associated with neurodegenerative diseases like Alzheimer’s
5. Traditional & Holistic Health Benefits
In Traditional Chinese Medicine (TCM), mulberry leaves are prized for their:
- Cooling properties, supporting liver and lung health
- Ability to alleviate dry coughs and eye discomfort (often consumed as mulberry leaf tea with honey)
