Mulberry (Folium mori)leaf extract DNJ
Product Introduction
Mulberry leaf extract DNJ is a natural bioactive alkaloid raw material extracted and refined from high-quality fresh mulberry leaves of Morus alba L., with 1-deoxynojirimycin (DNJ) as the core active ingredient. As a professional plant extract manufacturer for more than 15 years, we use water/ethanol technology to get an off-white to light yellow fine uniform powder with no visible foreign impurities, no caking, a pure texture, and good fluidity, which is convenient for industrial batching and mixing. Our products fully meet industrial production and formula compounding standards.
All batches pass third-party SGS heavy metal testing. Strictly comply with EU food-grade industrial standards: Lead (Pb) ≤2.0mg/kg, Arsenic (As) ≤1.0mg/kg, Cadmium (Cd) ≤0.3mg/kg, Mercury (Hg) ≤0.1mg/kg. No heavy metal exceeding standards, no pesticide residue, no solvent residue, fully compliant with food, pharmaceutical and cosmetic industrial safety access requirements.
Product benefits
Powerful α-Glucosidase Inhibition: DNJ is a natural high-efficiency α-glucosidase inhibitor, which can effectively delay the decomposition and absorption of intestinal carbohydrates, significantly reduce postprandial blood sugar peaks, and is the core raw material for hypoglycemic functional products.
Antioxidant & Anti-Inflammatory: Rich in mulberry polyphenols and flavonoids, it can improve human antioxidant capacity, reduce inflammatory reactions, and assist in improving cardiovascular metabolic health, verified by PMC clinical studies.
Regulate Blood Lipid & Metabolism: Synergistically act with rutoside and other active ingredients to balance blood pressure, reduce blood lipid accumulation, and promote human metabolic circulation with stable metabolic regulation efficacy.
product strength
Chemical Stability: Optimized purification process removes unstable impurities, the molecular structure of DNJ is stable, resistant to conventional industrial high-temperature sterilization, low-temperature freezing and acid-base blending, no active ingredient loss during production processing, ensuring consistent end-product efficacy.
High Bioavailability: Our mulberry leaf extract maximizes the preservation of DNJ's biological activity; its small-molecule structure facilitates easier absorption by the human body, allowing the desired efficacy to be achieved at lower inclusion rates in blood sugar management formulations.
Formulation Stability: In standard food and dietary supplement systems (pH 3–7), the extract maintains an activity retention rate of ≥95% for over six months. It is resistant to interactions with other vitamins or minerals in the formulation, significantly simplifying the product development process for downstream clients.
High Batch-to-Batch Consistency: Leveraging an automated continuous production process, DNJ content variation between batches is controlled within ±0.1%, preventing inconsistencies in end-product efficacy caused by fluctuations in raw material composition.
product Applications
Dietary Supplement Industry: DNJ is widely used in capsules, tablets, and blended powders designed for blood sugar management, serving as a key, high-demand ingredient in sugar-control supplements across European and American markets.
Functional Food and Beverage: Mulberry leaf extract can be incorporated into products such as sugar-control meal replacement powders, sugar-free teas, and cereal bars, imparting blood sugar management benefits without significantly altering the flavor profile.
Weight Management Formulas: When combined with dietary fiber and other bioactive plant ingredients, it helps reduce the conversion of carbohydrates into calories, making it suitable for weight management health products.
Pet Nutrition: It is added to functional nutritional supplements for aging pets, helping companion animals maintain a healthy metabolic state.
Cosmetics Industry: Leveraging its potential tyrosinase-inhibiting activity, it is used in the formulation of skincare products designed for skin brightening and oil control.

FAQ
Q: Can you customize DNJ content and product specifications?
Yes. We support full-range customization of DNJ content from 1% to 10% (HPLC standard), and can adjust particle size, moisture, solubility and microbial indicators according to customer’s industrial application scenarios (beverages, tablets, pharmaceutical intermediates, etc.) to meet different production process standards.
Q: Are your products compliant with international safety standards?
All products pass SGS third-party testing, heavy metal and microbial indicators fully comply with EU food-grade standards and international plant extract safety specifications. The factory has ISO22000, HACCP and other authoritative certifications, with complete qualification documents, supporting global market sales and customs clearance.
Q: What is the solubility and storage stability of the product?
The product is completely water-soluble, clear and transparent after dissolution without precipitation and turbidity. Sealed and stored in dry and cool environment, the shelf life is 24 months, with stable DNJ content and chemical properties within the shelf life, no decomposition and deterioration, and stable batch quality.
Q: What is your bulk supply capacity and delivery cycle?
We have standardized industrial production lines with sufficient raw material reserves, annual output up to 20 tons, supporting large-scale bulk orders.
