Mulberry Leaf Extract Powder

Premium Mulberry Leaf Extract Powder for Metabolic Health Solutions – GMP Certified Natural Ingredient

Xi'an Jiayuan Bio-tech Co., Ltd. specializes in high-quality Mulberry Leaf Extract Powder, a standardized botanical ingredient derived from Morus alba L. leaves. We started in 2002 with RMB 30 million in registered capital. We have 30 technicians and two GMP-certified production lines. HPLC and UV indicate that our extract contains 1-10% DNJ (1-Deoxynojirimycin) and 5-20% flavonoids.

Our ISO9001, FSSC22000, HALAL, KOSHER, and HACCP certifications assure consistent product batches to international standards. All shipments come with COA documentation, heavy metal testing (lead ≤2.0ppm, arsenic ≤1.0ppm), and pesticide residue screening to USP/EP standards.

What Is Mulberry Leaf Extract Powder?

This product is a concentrated Morus alba L. leaf extract made using contemporary extraction and spray drying methods. An effective professional alpha-glucosidase inhibitor based on the alkaloid 1-Deoxynojirimycin.

DNJ (1%-10%), flavonoids (5%-20%), and polyphenols (up to 102.0 mg/g) are assessed in our extract, not a raw leaf powder. This standardisation addresses formulation difficulties such seasonal potency variation and raw botanical bioavailability.

The extract is a fine, hygroscopic yellow-green to light yellow-brown powder. Its water solubility and heat stability up to 120°C make it suitable for pasteurisation and other processing methods.

Functions

Our extract has synergistic bioactive ingredients for multi-target health effects. DNJ is a natural alpha-glucosidase inhibitor and is used for the control of postprandial blood glucose. Clinical trials show better glucose metabolism and increased insulin sensitivity.

Its extensive profile of flavonoids and polyphenols gives it high antioxidant potential. These substances have been shown to improve cardiovascular health by decreasing blood cholesterol and triglyceride levels. Hepatoprotective effects: Lower ALT and AST in people with fatty liver problems.

Another important role is modulating gut microbiome. The extract reversed high-fat diet-induced microbiota imbalance by decreasing the Firmicutes/Bacteroidota ratio and raising beneficial Bifidobacterium populations. This pathway leads to decreased inflammation and better metabolic problems.

Anti-obesity actions via the gut microbiota-metabolite axis. Animal studies demonstrate lower weight growth, decreased fat formation and better lipid metabolism via modulation of glycerophospholipid and tryptophan pathways.​​​​​​​

 

Application Fields

Dietary Supplements: Capsules, pills and softgels formulated for blood sugar health control and metabolic health support. Common doses are 300-600mg daily which would provide 3-6mg of pure DNJ each dose.

Functional Beverages: Added to low-pH beverages, such as kombucha and energy drinks. Additional filtering on water-soluble grades provides clarity and bioactive stability at pH 3.5-6.0.

Weight Management Formulations: Used with other botanicals in fat-burning and metabolism-boosting products. The anti-obesity characteristics of the extract support complete weight management methods.

Functional Foods: Incorporated into nutrition bars, protein powders and meal replacement items. Thermal stability up to 120°C enabling inclusion into processed food matrices without bioactive degradation.

Quality Control

We have a full quality control system covering all stages of manufacturing. The raw materials are selected from the best mulberry-growing areas in Sichuan, Guangxi and Shandong, and are manually selected to ensure that the leaves are intact.

Every batch is tested thoroughly, including measurement of DNJ by HPLC or total flavonoids by UV spectrophotometry. Heavy metal screening confirms compliance with lead ≤2.0ppm and arsenic ≤1.0ppm. Pesticide residue testing involves testing for glyphosate to international standards.

Microbiological testing verifies that the total plate count and levels of yeast, mould, E. coli and Salmonella are in compliance with USP/EP requirements. Products are validated as non-GMO, allergen-free, gluten-free, and non-irradiated using established testing processes.

Professional laboratory facilities staffed by trained technicians conduct in-process and finished product analysis of Mulberry Leaf Extract Powder. Periodic third-party verification by SGS provides additional quality assurance.

FAQ

Q: How do you ensure the quality and safety of the product?

A: We have a complete chain quality control system from raw material to completed product. The raw materials are supplied from high-quality mulberry leaf growing areas in Sichuan, Guangxi and Shandong, with manual selection to guarantee leaf integrity and quality. All batches are tested for DNJ content (HPLC), total flavonoids (UV), and for heavy metals (lead ≤2.0ppm, arsenic ≤1.0ppm), pesticide residues (including glyphosate), and microbiological contaminants according to USP/EP standards. The products are non-GMO, non-allergenic, gluten free and non-irradiated. Each batch arrives with a full COA, spec sheet and MSDS with periodic third party verification (eg SGS).

Q: How long does it take to fill my order?

​​​​​​​A: Lead time depends on order type. Standard specifications in stock (e.g. 1% DNJ, 10:1 extract) arrive within 1-3 business days. Custom specs (5% or 10% DNJ content, for example) take 7-10 business days. Bulk commercial orders (metric-ton quantities) need 15-20 business days to assure batch uniformity and full quality testing. Sample orders (100g to 1kg) are available to be delivered in 1-2 business days. Please check with our sales staff at time of purchase for lead times, as high seasons or holidays may necessitate modest extensions.

Q: Is there a difference in efficacy between water extraction and ethanol extraction?

A: Yes. Water extraction preferentially yields polysaccharides and moderately yields DNJ but may extract more impurities. Hydro-ethanolic extraction is superior for concentrating DNJ and flavonoids while reducing sugar content, generally preferred for blood sugar management supplements.

Q: Can this extract be used in low-pH beverages?

A: Yes. Mulberry leaf bioactive compounds are generally stable at pH 3.5-6.0. However, for clear beverages, we recommend a specific water-soluble grade that has undergone additional filtration to remove insoluble chlorophyll and waxes.

Q: What is the recommended dosage for significant hypoglycemic effect?

A: Clinical studies suggest a daily intake of 3-6mg of pure DNJ. Therefore, if using a 1% DNJ standardized product, the recommended dosage is approximately 300mg to 600mg per day, typically taken before meals.
