• Comprehensive Testing Protocols That Ensure Consistent Quality

Quality assurance represents the cornerstone of our operational philosophy at Hongda Phytochemistry. Every batch of Diosmin Powder undergoes extensive testing before receiving approval for shipment. Our analytical protocols begin with raw material verification, where incoming citrus material is assessed for botanical identity, origin confirmation, and preliminary screening for obvious contamination. Once extraction commences, in-process testing monitors critical parameters including extraction efficiency, pH levels, and intermediate purity. The finished Diosmin Powder then faces a comprehensive battery of tests covering physical, chemical, and biological characteristics. Physical testing evaluates appearance to confirm the characteristic grayish yellow to light yellow color, odor assessment to detect any off-notes that might indicate degradation, bulk density measurement to ensure consistent handling properties, and particle size distribution analysis to verify appropriate micronization. Chemical testing employs HPLC methodology to quantify Diosmin content against our 90% minimum specification, measures moisture content through loss on drying procedures, determines ash content as an indicator of inorganic impurities, and screens for residual solvents that might remain from extraction processes. Heavy metal analysis specifically tests for lead, arsenic, cadmium, and mercury using atomic absorption spectrophotometry, with acceptance criteria significantly more stringent than international limits. Microbiological testing includes total plate count, yeast and mold enumeration, and screening for specific pathogens including E. coli, Salmonella, and Staphylococcus aureus. Beyond our internal laboratory capabilities, we maintain partnerships with internationally recognized third-party testing organizations including SGS and Eurofins. These independent laboratories conduct pesticide residue screening covering hundreds of compounds, perform aflatoxin testing when applicable, and can execute specialized analyses such as specific optical rotation measurements when customers require additional verification.
