What Is Rehmannia Extract?

This compressed plant material is produced from the tuberous roots of Rehmannia glutinosa LIBOSCH. This quality extract touches on some of the big difficulties that affect firms, such as shifting source material, the necessity for standardization and keeping contamination under control.

The bioactive compounds such as catalpol, rehmannioside D and verbascoside are alive when extracted with water and alcohol and spray dried at low temperatures. The extract dissolves well in water as long as the pH level is between 4.5 and 7.5. Bulk density is 0.40-0.65 g/ml. Moisture is less than 5%. It is ideal for tablets, pills and health drinks, since it does not absorb water when heated and it remains robust.

Core Functions

Our extract offers dual-action advantages, including biomarker quantification:

Anti-Inflammatory Mechanism: Inhibits MAPK and NF-κB signaling pathways, leading to a decrease in inflammatory cytokines (TNF-α and IL-1β) by up to 40% in preclinical tests. This pathway regulation promotes joint health and metabolic wellbeing.

Antioxidant Protection: Increases endogenous antioxidant enzymes (SOD, GSH-Px) and reduces lipid peroxidation indicators (MDA). This dual impact results in neuroprotection and promotes cognitive performance in aging populations.

Adaptogenic Support: Our extract may aid in the control of cortisol production in times of prolonged stress, and has a traditional usage in HPA axis management. Clinical data demonstrates enhanced neurocognitive function in fatigue related procedures.

FAQ

Q: What product certifications and compliance documentation do you have?

A: We can give full certifications such as ISO9001, FSSC22000, HALAL, Kosher, organic certifications (EU Organic, NOP) based on needs. The SC certification is standard in the production facility. Each shipment is accompanied with batch specific Certificate of Analysis (COA) specifying amount of active ingredients, heavy metals and microbiological restrictions. Factory audit access and third-party testing results accessible upon request.

Q: How do you make sure quality is the same from batch to batch?

A：We ensure quality consistency via regulated extraction methods and standardized testing. Each batch is evaluated for important markers such level of catalpol (standardized to 1% by HPLC), heavy metals (Pb ≤1 PPM, As ≤0.5 PPM) and microbiological limitations. We use alcohol/water extraction, low temperature concentration and spray drying in our manufacture to protect active chemicals. For specifications such as 10:1, 20:1 and 50:1 extract ratios, we use the same testing techniques.

Q: What is your supply ability and manufacturing capacity?

A: We have an ongoing supply capability of over 5,000 kg per month and scalable infrastructure to accommodate yearly outputs up to 5,000,000 kg. Samples have a minimum order quantity of 1 kilogram, while commercial orders need a minimum of 25 kg. The vertical integration from the cultivation bases to final manufacturing provides a steady supply throughout the year, reducing seasonal interruptions.
