Next-Generation Liver Health & Hangover Relief: SRBio High-Purity DHM
(China Organic Farm Direct · 99.2% Purity · Pharmaceutical-Grade Process)
SRBio’s Dihydromyricetin (DHM) is more than a simple flavonoid extract. It is a genomics-traced, pharmaceutical-grade active ingredient. By integrating our 200-hectare certified organic tea farms (QTPP-certified) in Fujian with our patented subcritical water/CO₂ hybrid extraction technology, we deliver DHM powder with an average purity of 99.2%—far exceeding the 92-95% industry average—providing global brands with a scientifically validated solution for alcohol metabolism support and liver protection.
Uncompromising Quality: SRBio’s Manufacturing Excellence
-
Genomics Sourcing & Vertically Integrated Supply Chain
-
Own Organic Farms: We control quality at the source with 200 hectares of QTPP-certified organic farms in Fujian for Ampelopsis grossedentata (Vine Tea). Soil pH is strictly maintained at 5.2-6.0 to optimize natural flavonoid accumulation.
-
DNA Barcoding Authentication: Every raw material batch is authenticated via DNA barcoding (ITS2 + psbA-trnH markers). Batches with <98% genetic match are rejected.
-
Infrared Low-Temperature Drying: Raw material is dried at 45°C using infrared technology, reducing water activity to <0.3 and preserving maximum natural bioactivity.
-
-
Patented Extraction & Pharmaceutical-Grade Purification
-
Subcritical Water/CO₂ Hybrid Technology: Our patented hybrid technology achieves a highly concentrated 12:1 ratio, efficiently enriching target flavonoids far beyond the standard 20-25:1 range.
-
Dynamic MAC (Mixed Adsorbent Column) Technology: During extraction, MAC technology is used to specifically capture and enrich DHM, significantly boosting extraction efficiency.
-
Preparative HPLC Purification: Final purification is performed using a Waters Preparative HPLC System (C18 column, 250×50mm, methanol/water gradient) to target and remove key impurities like Dihydroquercetin (DHQ) , ensuring DHQ <0.5%.
-
Triple Recrystallization: Three cycles of recrystallization (ethyl acetate/hexane) achieve pharmaceutical-grade purity standards.
-
-
Particle Engineering & Long-Term Stability
-
Micronization: Processed with a jet mill to achieve particle size D90 < 15 microns, significantly improving dissolution rate and bioavailability.
-
Lyophilization (Freeze-Drying): Performed at -45°C/0.01mbar to control moisture to <1%, ensuring excellent stability.
-
Protective Packaging: Packaged in trilayer foil bags, nitrogen-flushed with integrated oxygen scavengers, guaranteeing >98% purity retention after 24 months under ICH Q1A(R2) accelerated stability testing (40°C/75% RH).
-
Scientific Evidence: Mechanism & Clinical Research
-
Accelerated Alcohol Metabolism & Hangover Relief
-
Mechanism: DHM is a potent activator of the key enzymes alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). It accelerates the conversion of ethanol to acetaldehyde and then to harmless acetate, reducing peak blood alcohol and toxic acetaldehyde levels.
-
Clinical Data:
-
Alcohol Clearance: Studies show DHM significantly lowers blood alcohol concentration and shortens intoxication time (Shen et al., 2012).
-
Symptom Improvement: A clinical trial found that individuals taking DHM experienced significantly less headache, dizziness, nausea, and weakness after alcohol consumption (Kim et al., 2017).
-
-
-
Liver Protection & Metabolic Regulation
-
Mechanism: Through its potent antioxidant activity, DHM reduces alcohol-induced oxidative stress and inflammation in the liver. It also modulates lipid and glucose metabolic pathways.
-
Research Review: Over 279 studies on PubMed and Google Scholar confirm DHM’s antioxidant, anti-inflammatory, anticancer, antimicrobial, cell death-regulating, and lipid/glucose metabolism-regulating activities (Li et al., 2017).
