Product Introduction
The Natural α-Glucosidase Inhibitor
Mulberry Leaf Extract is derived from the leaves of Morus albaL. Our extract is precisely standardized to DNJ (1-Deoxynojirimycin), a potent alkaloid that functions as a competitive inhibitor of α-glucosidase.
DNJ acts mechanically within the gastrointestinal tract. It binds to the active site of the α-glucosidase enzyme, preventing the breakdown of disaccharides (such as sucrose, maltose, and lactose) into absorbable glucose. This enzymatic inhibition delays carbohydrate digestion, effectively flattening postprandial blood glucose curves and reducing the metabolic impact of high-sugar meals.
Mechanism of Action: Competitive Inhibition of α-Glucosidase → Delayed Conversion of Disaccharides to Glucose → Reduced Glycemic Spike.
Core Advantages
1. Precise Enzyme Inhibition
Standardized DNJ content (1%, 2%, 5% HPLC) ensures consistent α-glucosidase inhibitory activity.
2. Targeted Sugar Blocking
Specifically targets the digestion of sucrose, maltose, and lactose—preventing rapid glucose absorption.
3. HPLC-Verified Potency
DNJ is quantified via HPLC (not just UV), guaranteeing accurate alkaloid concentration and batch consistency.
4. Natural & Food-Grade
Sourced from edible mulberry leaves; Non-GMO; suitable for long-term dietary use.
5. Processing Stability
Exhibits good stability in low-moisture foods and moderate heat processes (e.g., baking).
Key Benefits
①Postprandial Glucose Management: Slows the conversion of carbohydrates into glucose, mitigating blood sugar spikes after meals.②Carbohydrate Blocker: Inhibits α-glucosidase, reducing the absorption rate of sugars from desserts, fruits, and starches.
③Antioxidant Support: Contains flavonoids (e.g., Rutin, Quercetin) that help combat oxidative stress associated with metabolic syndrome.
④Lipid Metabolism Support: May contribute to maintaining healthy triglyceride and cholesterol levels already within the normal range.
