Pure Luteolin Powder - Premium Plant Extract by Shaanxi Hongda Phytochemistry

Shaanxi Hongda Phytochemistry, an experienced manufacturer and supplier of high purity plant extracts, has more than 20 years of experience. 97% Pure Luteolin Powder is the top of natural flavonoid extraction technique, with 98% purity using modern HPLC verification methods. As a professional manufacturer, we supervise the whole supply chain from our certified Sophora japonica planting bases to our 100,000-level purification workshops, which guarantees the consistent quality complying with worldwide pharmaceutical requirements. Select our luteolin powder for a thermally stable and bioavailable ingredient with extensive third-party testing, detailed documentation and an array of customisation options for faster product development and reduced sourcing risks.

Product Introduction

The product is a high-end flavonoid compound extracted out of Sophora japonica buds utilising proprietary processes developed in our ISO-certified facility. This light yellow crystalline powder is extremely pure with an assay of 98% by HPLC, molecular formula C15H10O6, CAS number 491-70-3. The compound has a melting point over 328°C and excellent thermal stability suitable for a range of processing settings. Our extraction procedure retains the important hydroxyl groups that enable more free radical scavenging activity than typical flavonoid products.

Products Description

Pure Luteolin Powder Advantages

Superior Bioavailability: Our aglycone structure allows for quicker absorption and blood-brain barrier passage compared to glycoside versions, using 30-40% less to get the same therapeutic benefit.

Exceptional Stability: The high melting point and controlled particle size distribution ensure minimal degradation during tableting, encapsulation, or heat-shear processing applications.

Improved Solubility Solutions: We can provide micronised grades with D90 <10μm particle size to improve dispersion in aqueous formulations and purity.

Comprehensive Documentation: Every batch includes full traceability records, third-party certificates, and regulatory compliance documentation for FDA, EFSA, and Health Canada requirements.

Production Process

Step 1 - Raw Material Selection: We collect Sophora japonica buds at peak bloom from our certified organic farms, ensuring maximum luteolin content and verified free of pollutants by laboratory testing.

Step 2 - Extraction Optimisation: Specific temperature and pressure parameters are used to control the extraction of ethanol to ensure maximal flavonoid content is extracted, while minimising co-extractives and guaranteeing compliance with residual solvent levels.

Step 3 - Purification Refinement: Multi-stage recrystallisation and column chromatography separation ensures the removal of contaminants and results in Pure Luteolin Powder consistently exceeding 98% purity as proven by HPLC analysis.

Step 4 - Quality Verification: The final items are tested for identification confirmation, purity assay, heavy metal screening and microbiological examination before releasing from the warehouse.

Pure Luteolin Powder Application

Neuroprotective Formulations: Because of its superior ability to cross the BBB, it’s used in cognitive health supplements to modulate glial cells and manage neuroinflammation.

Anti-inflammatory Products: It is an effective modulator of IL-6 and TNF-α cytokine pathways in joint health and systemic inflammation formulae.

Skincare Innovations: Used in cosmeceutical preparations for its photoprotective effects and collagen preservation benefits in anti-aging formulas.

Sports Nutrition: Included in recovery goods to reduce inflammation and regulate oxidative stress in muscles after exercise.
