Xi'an DN Biology delivers Marshmallow Extract Powder sourced from Althaea officinalis L. roots through advanced plant extraction technology. Our facility processes up to 3,000 tons annually with a 10:1 concentration ratio (TLC-verified), ensuring 20% standardized flavonoids measured by UV spectrophotometry.
Every batch passes through our independent laboratory equipped with HPLC, GC, and UV-Vis systems. We maintain 100 tons of ready stock with 7-day rapid dispatch for in-stock orders.
Our brown-yellow fine powder (80 mesh) offers water solubility ideal for capsules, functional beverages, and topical formulations. Certified under ISO9001, GMP, HACCP, Kosher, and Organic standards, we guarantee heavy metals ≤10ppm and microbial counts ≤1,000 cfu/g. Flexible OEM/ODM services accommodate your custom specifications with production cycles of just 7–15 days.
You need consistency in every batch. That's why our extraction process begins with full-chain traceability from our integrated planting base.
Traditional crude root powders carry unpredictable potency and high contamination risks. Our concentrated format eliminates these variables. We use low-temperature vacuum drying combined with spray-drying techniques to preserve mucilage integrity—those critical polysaccharides including glucans and arabinogalactans.
The result? Predictable viscosity, film-forming properties, and therapeutic performance in your formulations. Unlike synthetic thickeners, you get a clean-label ingredient with thermal stability up to 60°C.
Our standardized extraction ensures you're not guessing at active compound levels. Each Certificate of Analysis documents the exact input-to-output biomass weight alongside TLC fingerprinting.

Standardized Potency You Can Check
Our facility’s root-derived extracts have a mucilage level of 35%, which is far higher than leaf-derived extracts. These are great for digestive and respiratory health purposes.
Standardized non-GMO maltodextrin variants and carrier-free versions meet clean label regulations. The latter enhances flowability for capsule-filling machines while remaining pure.
Performance-Ready Formula
Particular treatment of high polysaccharide content. Our Marshmallow Extract Powder can be easily included by high shear mixing or pre-dispersion in glycerin. This prevents the clumping of cold-process formulations.
The mucilage is stable in the pH range 4.0–7.0. It is suitable for use in functional teas, health shots and acidic beverage systems without losing efficacy.
Three-Layer Quality Control
Our inspection methodology includes what matters to your production team:
Botanical Identification - HPTLC separates Althaea officinalis from common adulterants, such as Althaea rosea.
Heavy Metal Profiling — ICP-MS testing finds Lead <3ppm, Arsenic <2ppm, Cadmium <1ppm, Mercury <0.1ppm
Organic requirements - We screen for over 200 chemicals to meet EU and USDA organic requirements.
Always supports 3rd party lab testing Free samples will be provided before shipment for your check quality before you make full order.

Nutraceutical Formulations
Your customers with GERD or leaky gut need elements that work. Our extract is protective for the esophagus and stomach lining and is effective even in severe acid conditions.
It's a critical ingredient in digestive health capsules, gut health powders and liquid extracts for nootropic formulations. The demulcent qualities provide some measurable relief above basic fibre supplements.
Advanced Cosmeceutical
Sensitive skin and eczema-prone skin needs gentle, yet powerful substances. Our powder naturally inhibits the enzyme hyaluronidase and is an anti-inflammatory.
This increases skin moisture and barrier function. It is used in serums, lotions, and masks by formulators, however synthetic substitutes may cause irritation. The bioadhesive characteristics ensure long-term interaction with skin tissue.
Throat Care Pharmaceutical Grade
Our extract also has enhanced relaxing properties that are helpful in dry cough medicines and pharyngeal care products. Mucilage is used in syrups and lozenges to permit prolonged contact with the mucosa of the throat.
It is more lasting and more comfortable than syrups based on sugar. Our product passes pharmaceutical grade criteria for microbiological limits: Negative for E. coli, Salmonella and Staphylococcus aureus.

You’re not just buying powder. You’re getting a supply chain partner.” Leave the challenging logistics to our 24/7 customer response team and skilled export division.
We offer DDP shipping services and different transit solutions. Our flexible minimums and substantial stock have you covered whether you require 1kg for R&D testing or 10 tons for commercial manufacturing.
Factory inspection welcome. Our 4 extraction vessels (6m³ each), 3 integrated concentration systems and state-of-the-art analytical lab regularly turn inquiries into long-term partnerships.

We put in 25 kg fibre drums with double food grade polythene bags within. This prevents moisture and contamination during overseas delivery.
Store in a cool dry location away from direct light. Containers should be properly sealed to ensure potency for 24 months from the manufacturing date.
We offer custom packaging for private label products or unique regulatory needs for your target market.
Q: What is the difference between root-derived and leaf-derived product?
A: Root extracts typically contain higher mucilage content (up to 35%) and are preferred for digestive and respiratory health, whereas leaf extracts are often used for milder topical applications.
Q: How does the extract behave in cold-process formulations?
A: Due to its high polysaccharide content, it requires high-shear mixing or pre-dispersion in glycerin to prevent clumping and ensure a smooth, homogeneous solution.
Q: Is the powder stable in low pH beverage applications?
A: Yes, the mucilage remains stable and functional between pH 4.0 and 7.0, making it suitable for functional teas and health shots.
Q: How do you verify the 10:1 extract ratio?
A: We provide a Certificate of Analysis (CoA) documenting the input-to-output biomass weight, alongside TLC fingerprinting to confirm concentrated characteristic markers.
Q: Does your extract contain maltodextrin as a carrier?
A: We offer both 'Carrier-Free' versions for clean-label requirements and 'Standardized' versions with non-GMO maltodextrin to improve flowability and stability for capsule-filling machines.
