Overview
Mulberry Leaf Extract is derived from the leaves of the Morus alba L. tree, a plant traditionally used in Chinese medicine for its therapeutic properties. The extract is rich in bioactive compounds, including flavonoids, polyphenols, and 1-deoxynojirimycin (DNJ), which contribute to its health benefits. Modern applications span pharmaceuticals, dietary supplements, and skincare products due to its antioxidant and anti-inflammatory effects. The extract is typically produced through solvent extraction or supercritical CO2 extraction, ensuring the preservation of its active ingredients. Its growing popularity in the nutraceutical industry is driven by increasing consumer demand for natural and functional ingredients. Research continues to explore its potential in managing metabolic disorders, particularly diabetes, due to its ability to inhibit carbohydrate absorption.
Physical and Chemical Properties
Mulberry Leaf Extract is usually available as a brownish-yellow powder or liquid, with a mild, herbal aroma. The powder form has a density of approximately 0.5-0.7 g/cm³ and is highly soluble in water and ethanol, making it versatile for formulation in various products. The extract's stability depends on storage conditions, with degradation accelerated by exposure to light, heat, or moisture. Key bioactive components include flavonoids like quercetin and kaempferol, polyphenols such as chlorogenic acid, and DNJ, a potent alpha-glucosidase inhibitor. These compounds are responsible for the extract's antioxidant capacity, measured by ORAC (Oxygen Radical Absorbance Capacity) values, which can range from 5,000 to 20,000 μmol TE/g depending on the extraction method and source material.
Main Applications
In the pharmaceutical industry, Mulberry Leaf Extract is valued for its potential to support blood sugar management, making it a key ingredient in diabetic supplements. Its anti-inflammatory properties are leveraged in formulations targeting metabolic syndrome and cardiovascular health. The nutraceutical sector incorporates the extract into capsules, tablets, and functional beverages for its antioxidant benefits and ability to promote weight management. Cosmetics and skincare products utilize the extract for its anti-aging effects, as it helps neutralize free radicals and reduce oxidative stress on the skin. It is commonly found in serums, creams, and masks. Additionally, the food industry employs Mulberry Leaf Extract in functional foods and beverages, such as teas and health drinks, capitalizing on its natural origin and health-promoting properties.
Safety and Storage
Mulberry Leaf Extract is generally considered safe for consumption and topical use, with no significant adverse effects reported at recommended dosages. However, individuals with allergies to mulberry or related plants should exercise caution. Regulatory bodies like the FDA classify it as GRAS (Generally Recognized as Safe) when used in accordance with good manufacturing practices. Proper storage is critical to maintaining the extract's efficacy. It should be kept in a cool, dry place, ideally at temperatures below 25°C (77°F), and protected from direct light and humidity. Packaging typically includes airtight containers with desiccants to prevent moisture absorption. Shelf life ranges from 18 to 24 months when stored correctly, though manufacturers should verify stability data for specific formulations.
B2B Procurement Guide
When sourcing Mulberry Leaf Extract, B2B buyers should prioritize suppliers who provide detailed certificates of analysis (COAs), including DNJ content, purity levels, and heavy metal testing results. Organic certification may be required for products targeting health-conscious markets. Bulk pricing varies significantly based on DNJ concentration, with higher-purity extracts (e.g., 10% DNJ) commanding premium prices. Procurement professionals should evaluate extraction methods, as supercritical CO2 extraction yields higher-quality extracts but at a greater cost. Reliable suppliers often offer custom formulations, such as water-soluble or standardized extracts, to meet specific application needs. Lead times can range from 2-6 weeks depending on order volume and customization requirements, so planning ahead is advisable to avoid supply chain disruptions.
