Rhamnose Sophora Rice
Overview
Rhamnose Sophora Flower Bud refers to the dried flower buds of Sophora japonica (Japanese pagoda tree) that contain significant amounts of rhamnose, a naturally occurring deoxy sugar. This botanical material has been used in traditional Chinese medicine for centuries, particularly valued for its flavonoid content and potential health benefits. The plant material is typically harvested in early summer when the flower buds are fully formed but not yet opened. Modern extraction techniques allow for the concentration of active compounds, making it valuable for both traditional and contemporary applications in the health and pharmaceutical industries.
Physical and Chemical Properties
The primary active component, rhamnose (C6H12O5), is a methyl pentose sugar that contributes to the material's biological activity. The flower buds contain a complex mixture of flavonoids (particularly rutin), polysaccharides, and other phytochemicals that give the material its characteristic yellowish-brown color and slightly bitter taste. Rhamnose Sophora Flower Bud demonstrates moderate solubility in polar solvents, with the extracted compounds showing stability under proper storage conditions. The material's antioxidant properties are particularly notable, with ORAC (Oxygen Radical Absorbance Capacity) values comparable to many well-known medicinal plants.
Main Applications
In traditional medicine systems, Rhamnose Sophora Flower Bud has been used to support circulatory health and as an anti-inflammatory agent. Modern applications include its use as a raw material for rutin extraction, which is converted to quercetin for pharmaceutical formulations. The material finds significant use in the nutraceutical industry as a dietary supplement ingredient, particularly in formulations targeting vascular health. In cosmetic applications, it serves as a natural active ingredient in anti-aging and skin-brightening products due to its flavonoid content and antioxidant properties.
Safety and Storage
Rhamnose Sophora Flower Bud is generally considered safe when used appropriately. However, as with any botanical material, quality control is essential to ensure the absence of contaminants such as heavy metals or pesticide residues that might accumulate from cultivation. Proper storage requires protection from moisture and sunlight to prevent degradation of active compounds. The material should be kept in airtight containers at room temperature or below, with desiccants recommended for long-term storage. Industrial-scale storage often involves climate-controlled environments to maintain product integrity.
B2B Procurement Guide
When procuring Rhamnose Sophora Flower Bud for commercial use, buyers should verify the geographical origin of the material, as growing conditions significantly affect phytochemical profiles. Reputable suppliers should provide certificates of analysis including heavy metal screening, microbial limits, and active compound quantification. For pharmaceutical applications, GMP (Good Manufacturing Practice) certification of processing facilities is essential. Bulk buyers should consider seasonal availability and potential price fluctuations, with advance contracts often securing better pricing. Testing for authenticity is recommended, as adulteration with less valuable plant materials has been reported in the market.
