Overview
Fructus Rosae Laevigatae Extract is derived from the fruit of Rosa laevigata, a plant native to East Asia. It has been used for centuries in traditional Chinese medicine for its purported health benefits. The extract is rich in bioactive compounds such as flavonoids, polyphenols, and triterpenes, which contribute to its therapeutic properties. Modern research has explored its potential as a natural antioxidant and anti-inflammatory agent, making it a popular ingredient in dietary supplements and cosmetic products. The extract is typically standardized to ensure consistent levels of active compounds, which is critical for efficacy in commercial applications.
Physical and Chemical Properties
Fructus Rosae Laevigatae Extract is commonly available as a fine, brownish-yellow powder with a characteristic mild aroma. It is soluble in water and ethanol, which makes it versatile for use in various formulations. The extract is stable under normal storage conditions but should be protected from excessive heat and moisture to maintain its potency. The primary active constituents include flavonoids like quercetin and kaempferol, as well as polyphenols such as gallic acid. These compounds are responsible for the extract's antioxidant capacity, which is often measured using ORAC (Oxygen Radical Absorbance Capacity) values. The exact chemical composition can vary depending on the extraction method and source material.
Main Applications
The extract is widely used in the dietary supplement industry, where it is incorporated into capsules, tablets, and liquid formulations for its potential health benefits. It is often marketed for immune support, anti-aging, and general wellness due to its antioxidant properties. In the cosmetic industry, Fructus Rosae Laevigatae Extract is valued for its skin-soothing and anti-inflammatory effects. It is commonly found in serums, creams, and lotions aimed at reducing redness and promoting skin health. Additionally, it is sometimes used in functional foods and beverages to enhance nutritional profiles.
Safety and Storage
Fructus Rosae Laevigatae Extract is generally considered safe for consumption and topical use when used as directed. However, individuals with known allergies to Rosaceae family plants should exercise caution. Pregnant or nursing women should consult a healthcare provider before use. Proper storage is essential to maintain the extract's efficacy. It should be kept in a tightly sealed container in a cool, dry place, away from direct sunlight. Bulk quantities should be stored in climate-controlled environments to prevent degradation. Shelf life typically ranges from 2 to 3 years when stored correctly.
B2B Procurement Guide
When sourcing Fructus Rosae Laevigatae Extract, B2B buyers should prioritize suppliers with transparent quality control processes. Key considerations include verifying certificates of analysis (CoA) for active compound levels and contaminants such as heavy metals or pesticides. It is advisable to work with suppliers who adhere to Good Manufacturing Practices (GMP) and have ISO certifications. Minimum order quantities (MOQs) can vary, so buyers should clarify this upfront. Sample testing is recommended to ensure the extract meets specific application requirements, such as solubility or purity standards for dietary or cosmetic use.
