Hefei Fushan Yuansheng Biotechnology Co., Ltd. provides high quality Abelmoschus Manihot Flower Total Flavonoids Extract, a standardised botanical component that has been identified for use in chronic renal disease and metabolic health support. Our extract contains total flavonoids content between 50% and 78% (dry basis), hyperoside ≥ 7.0% and isoquercitrin ≥ 5.0% which is validated by HPLC and UV tests.
Empowered by NMPA certification and 54 patented technologies accumulated from 13 years of in-depth functional nutrition research, we ensure consistent product quality and stable global supply. With an annual stable production capacity of 4.8 tonnes, we serve emerging health brands and leading pharmaceutical enterprises worldwide as a reliable long-term partner.

We use patented purification technology in our extraction process to eliminate dangerous contaminants such as resins and pesticide residues. This results in better safety profiles than ordinary botanical powders.

Exclusive Extraction and Purification Process
Our patented method eliminates harmful contaminants including pesticide residues and plant resins. This greatly improves the safety profile of your final goods and lowers formulation problems.
Seed to Supply Full Traceability
We have total traceability and quality control across the whole supply chain. Every stage starting from botanical verification by DNA barcoding to the final product release testing is recorded and verified.
Customisable Content Levels
We would be happy to do custom specs in the area of 50%-78% total flavonoids. For pharmaceutical formulations or nutraceutical applications, should you prefer increased hyperoside content or balanced profiles, we customise to your needs.
Annual Stable Capacity
We have a production capacity of 4.8 tonnes per year and we work on both pilot scale experiments and commercial contracts on a big scale. This provides continuous supply for your product launches and ongoing manufacturing demands.
Renal Health Supplements
The extract is often used in dietary supplements for chronic kidney disease and diabetic nephropathy. Abelmoschus Manihot Flower Total Flavonoids Extract is multi-targeted and targets the TGF-β1/Smads signalling system to suppress renal fibrosis and lower the amount of proteinuria.
Formulations for Metabolic Health
In the formulation for diabetics, the extract inhibits advanced glycation end products (AGEs) preventing microvascular problems. [4] This makes it a beneficial element for long-term blood sugar support.
Advanced Cosmeceuticals
Its anti-inflammatory and antioxidant characteristics make it a good choice for topical preparations. It serves as a natural UV-protector and reduces erythema and collagen degradation due to environmental stressors.
Compatible Dosage Forms
The raw substance may be processed into a variety of dosage forms such as tablets, capsules, patches, creams and gels. We also provide a specialised instant-soluble grade made via cyclodextrin encapsulation for functional beverage applications.
We know that effective product creation is more than simply high grade raw materials. That’s why we provide you total formulation assistance, customised for your requirements.
Custom Content Optimization
We adjust total flavonoids and marker compound ratios based on your target therapeutic outcomes and regulatory requirements.
Dosage Guidance and Blending Formulations
Our technical team provides evidence-based dosage recommendations and compatible excipient suggestions. This reduces your R&D time and accelerates time-to-market.
Multi-Dosage Form Adaptation Plans
Whether you're developing solid oral dosages or topical applications, we guide you through solubility enhancement, stability testing, and bioavailability optimization strategies.

Q:What is the difference between 'Total Flavonoids' and 'Hyperoside' content?
A:Total Flavonoids (measured by UV) represents the sum of all polyphenolic compounds in the extract. Hyperoside is the specific chemical marker used for potency validation via HPLC, ensuring batch-to-batch consistency.
Q:What storage conditions prevent degradation of flavonoids?
A:Store in a cool, dry, dark environment in airtight containers. Our stability tests confirm a 24-month shelf life when stored below 25°C with less than 50% humidity.
Q:Does the extract have any known contraindications with CKD medications?
A:Clinical data suggests it works synergistically with ARBs and ACE inhibitors. However, we recommend monitoring potassium levels during co-administration due to potential additive effects.
Q:Is the extract water-soluble for liquid formulations?
A:While total flavonoids have limited water solubility, we offer a specialized instant-soluble grade achieved through cyclodextrin encapsulation. This version is ideal for functional beverage applications.
Q:How is botanical authenticity verified?
A:We use HPTLC and DNA barcoding to ensure the raw material is 100% Abelmoschus manihot and not adulterated with other Malvaceae species. This guarantees botanical identity and compositional integrity.
