Mulberry Leaf extract 1-DNJ 10%

1.Product Introduction

 Mulberry leaf extract is produced from the processing of mulberry leaf powder obtained from the first to third new leaves on the branches of mulberry trees in late spring or before the first frost.
Mulberry Leaf Extract DNJ (1-Deoxynojirimycin) is a natural compound found in mulberry leaves. DNJ has gained interest in the scientific community due to its potential health benefits.
DNJ is known for its ability to inhibit the activity of the enzyme α-glucosidase, which is involved in the breakdown of complex carbohydrates into glucose in the digestive system. By inhibiting this enzyme, DNJ can help regulate blood sugar levels and prevent rapid spikes in glucose after meals.
Several studies have suggested that DNJ may have anti-diabetic properties and can be used as a natural supplement for managing diabetes. It is believed to improve insulin sensitivity, promote glucose uptake by cells, and reduce glucose absorption from the intestine.
In addition to its potential anti-diabetic effects, DNJ has also shown antioxidative and anti-inflammatory properties. It may help protect against oxidative stress and reduce inflammation in the body, which are associated with various chronic diseases.
Meanwhile the extract contains  others various physiologically active substances such as mulberry leaf flavonoids, mulberry leaf polyphenols, mulberry leaf polysaccharides and GABA, among others. It is used for the prevention and treatment of cardiovascular and cerebrovascular diseases, hyperlipidemia, diabetes, obesity, and anti-aging.
The active components of the mulberry leaf have effects such as regulating blood sugar, dispersing wind-heat, moistening the lungs, clearing the liver, and brightening the eyes. It is used for conditions such as wind-heat common cold, lung heat cough, headaches, dizziness, red and swollen eyes, and blurred vision. The active ingredients in mulberry leaf also have antioxidant, anti-aging, antibacterial, and moisturizing effects.

Raw Material & Extraction Foundation
The starting material is mulberry leaves grown under controlled agronomic practices, harvested at the optimal stage for highest phytonutrient content. As the plant extract supplier, we source Morus alba L. leaves, then deliver them to our manufacturing facility where our plant extract manufacturers apply water/ethanol extraction, concentration, purification and spray-drying or milling to produce the extract or powder format. The result is a brown-yellow fine product (mulberry leaf extract or mulberry powder) standardized to contain DNJ 10%, while retaining other botanical compounds such as flavones and polysaccharides. Our process ensures that the botanical integrity of mulberry leaf extract is preserved, while delivering consistent functional potency and formulation-friendly physical properties. Every stage—from raw leaf sourcing through extraction, milling and packaging—is monitored for traceability and quality control, ensuring you receive a product from a credible plant extract supplier with documentation and supply-chain reliability.

Functional Performance & Formulation Integration
Mulberry leaf extract (and related mulberry powder formats) is increasingly used in functional formulations thanks to its scientifically studied constituent 1-deoxynojirimycin (DNJ) which inhibits α-glucosidase activity and supports post-meal glucose regulation.  With a DNJ-standard content of 10%, this extract offers a meaningful dosage foundation for applications targeted at metabolic wellness, blood sugar management, antioxidant support, weight management or general botanical wellness. Whether used in capsules, tablets, powder blends, functional beverages or snack formats, this ingredient integrates smoothly thanks to its fine powder format, neutral taste profile and robust standardization. Because it originates from mulberry leaf extract or mulberry powder derived from the botanical source, brands can emphasise “plant-based botanical extract” positioning, align with consumer demand for clean-label ingredients, and rely on a plant extract supplier who provides documentation (COA, MSDS, specification sheets) to support formulation and regulatory needs.

Quality Assurance, Manufacturing & Supply-Chain Reliability
As your plant extract supplier and supported by seasoned plant extract manufacturers, our manufacturing facility is equipped for high-volume botanical extract production, milling, packaging and quality assurance. Each batch of Mulberry Extract DNJ 10% undergoes analytical testing for DNJ content (HPLC), heavy metals, microbial safety, particle size, moisture and residual solvents. Our supply chain supports global export, private-label readiness and OEM/ODM customisation—whether you require different specifications (DNJ 5%, 15% etc), specialised packaging, or formulation guidance. Because we are both the plant extract manufacturer and supplier, our back-end processes—from leaf sourcing to finished-packaging—are aligned for consistency, traceability and scalability. This allows your brand to scale from prototype to commercial launch with confidence in ingredient quality, documentation and supply continuity.
