Product Introduction
Mulberry leaf extract is a natural plant ingredient extracted from the leaves of the white mulberry (Morus alba L.). Mulberry leaves are rich in various bioactive compounds, including 1-deoxynojirimycin (DNJ), flavonoids, polyphenols, alkaloids, and antioxidants, and are widely used in traditional Asian herbal medicine.
Extract ratios: e.g., 4:1, 10:1, 20:1.
Active ingredient (deoxynojirimycin/DNJ): 1% to 5% 1-DNJ content (commonly found in hypoglycemic supplements).
Active ingredient (mulberry leaf flavonoids): 5%, 10%, 30% content (determined by UV spectrophotometry).
Mulberry leaf extract is widely used in dietary supplements, functional foods, beverages, and nutritional supplements due to its natural plant source and functional properties.
Key advantages and features: Natural plant source; extracted from carefully selected mulberry leaves using advanced extraction technology to retain active ingredients.
Rich in DNJ (1-deoxynojirimycin). DNJ is one of the characteristic compounds found in mulberry leaves and is often used as a quality indicator for mulberry leaf extracts.
Antioxidant properties: Contains flavonoids and polyphenols, exhibiting antioxidant activity.
Supports healthy metabolism and is often added to products designed to promote metabolic health and balanced nutrition.
Offers plant-based, non-GMO products with clean label ingredients, suitable for modern health-conscious consumers.

Functions and Usages
About Mulberry Leaf (*Morus alba*)
Mulberry leaf—the dried leaf of the *Morus* plant (family Moraceae)—is listed by the National Health Commission as a “dual-purpose” ingredient, meaning it serves as both food and medicine. In traditional Chinese medicine, it is used to disperse wind-heat, clear lung heat and moisten dryness, and clear the liver to improve eyesight. The *Compendium of Materia Medica* (*Bencao Gangmu*) refers to it as the “Immortal’s Herb.” It has a long history of widespread use in folk traditions, such as in teas and congees. Since the 1990s, mulberry leaf has become a popular functional food ingredient in Japan, hailed as a “secret to longevity”; products like “mulberry leaf green juice” became a craze, while mulberry leaf tea, noodles, and cookies also gained popularity. In Europe and the United States, mulberry leaf is recognized as a source of active ingredients that help lower blood sugar and support cardiovascular health.
WEHENGFOOD Mulberry Leaf Extract
WEHENGFOOD Mulberry Leaf Extract is produced from fresh young leaves harvested from mulberry branches during the late spring silkworm-rearing season. It is obtained through a process of crushing, extraction, fine filtration, concentration, (refining), and drying. It contains various active substances, including alkaloids (such as 1-deoxynojirimycin/1-DNJ), flavonoids, polyphenols, polysaccharides, and GABA. Among these, the alkaloid 1-DNJ inhibits the activity of disaccharidase enzymes, thereby suppressing the small intestine’s absorption of disaccharides and reducing postprandial blood glucose spikes.
WEHENGFOOD Mulberry Leaf Extract features excellent water solubility and a pure flavor profile. It is widely used in functional foods, pastries, cookies, beverages, confectionery, dairy products, and grain-based foods. It helps lower the Glycemic Index (GI) of foods and beverages, control postprandial blood sugar, alleviate the burden of insulin secretion, and reduce carbohydrate absorption.
Human clinical trials conducted on mulberry leaf extract product demonstrated that it inhibits postprandial blood glucose generation by up to 49.2%, reduces peak serum insulin levels by 69.3%, and lowers total insulin output by 65.0%. Key Benefits of Mulberry Leaf Extract
√ Lowers the Glycemic Index (GI) of foods and beverages
√ Controls postprandial blood sugar
√ Relieves the burden on insulin secretion
√ Reduces carbohydrate absorption
