- Product Description
Rhizoma Drynariae Extract Powder - Premium Botanical Extract for Bone Health Applications
Xi'an Linnas Biotech Co., Ltd. manufactures Rhizoma Drynariae Extract Powder through advanced hydro-ethanolic extraction and spray-drying technologies. Our extract's naringin content, which ranges from 2% to 20% and is confirmed by HPLC, is standardized to provide constant amounts of bioactive flavanones. Each batch, which is available in concentration ratios ranging from 10:1 to 50:1, keeps the moisture level and ash content below 5.0%, guaranteeing thermal stability for a variety of formulation procedures. Our facility guarantees pharmaceutical-grade quality for international bone health and nutraceutical manufacturers by operating under ISO 9001, HACCP, HALAL, and KOSHER certifications.
What Is Rhizoma Drynariae Extract Powder?
The dried rhizomes of the perennial epiphytic fern Drynaria fortunei (Kunze) J. Sm. are the source of this botanical concentration. Bioactive substances with osteogenic qualities are captured by the extract.
The chemical composition of traditional raw materials is frequently variable. This inconsistency is eliminated by our standardized extraction procedure. A consistent product with predictable therapeutic potential is given to you.
Controlled temperature and pressure parameters are used in the production process. Heat-sensitive phytochemicals are kept intact in this way. The end product is a powder that retains its bioactivity during formulation and storage.

Key Physical and Chemical Properties
The extract presents as a fine Rhizoma Drynariae Extract Powder with characteristic herbal odor and slightly bitter taste. Excellent dispersibility in both aqueous and hydro-alcoholic solutions is guaranteed by its 80-mesh particle size.
One unique benefit is thermal stability. This powder will not degrade when used in high-temperature granulation and tableting procedures. During prolonged storage, microbial growth is inhibited by the low moisture requirements.
Different delivery formats are supported by solubility profiles. The extract can be used in tinctures, liquid capsules, and topical treatments because it dissolves easily in ethanol-water solutions.
Diverse Application Scenarios
Bone Density Supplements: This extract is used by formulators into geriatric health medicines that address osteoporosis and osteopenia. It addresses issues with bone resorption by working in concert with calcium and vitamin D3 to promote osteoblast activity.
Sports Recovery Formulations: This extract's powders and capsules are beneficial to athletes. Because of the acidic environment of the digestive tract, it maintains stability while hastening the healing of stress fractures and ligamentous injuries.
Transdermal Delivery Systems: To treat localized fractures, pharmaceutical companies use the extract in healing patches. In adhesive matrices, the phytochemical stability enables active chemicals to maintain their efficacy during 24-hour wear cycles.
Functional Food Ingredients: The powder is added by health food producers to nutrition bars and fortified drinks. Integration is easy because of its interoperability with food processing machinery.
Quality Assurance and Compliance
At our internal laboratory, every production batch is put through a thorough testing process. We use HPLC fingerprinting against reference standards and microscopic inspection to confirm identity.
Heavy metal screening verifies adherence to global safety standards. Microbiological testing guarantees that the quantities of pathogens, yeast, mold, and total plate count satisfy pharmacopeial standards.
Our certifications make it easier for you to enter other markets. Manufacturing excellence is demonstrated by ISO 9001. Our food safety management is demonstrated by our HACCP accreditation. Middle Eastern and specialty dietary markets are opened by HALAL and KOSHER certifications.
Every shipment is accompanied by documentation. To expedite your compliance procedures, you receive Certificates of Analysis, Material Safety Data Sheets, and regulatory support documentation.

Frequently Asked Questions
Q: What solvents do you use for extraction?
A: To optimize the recovery of bioactive compounds while preserving safety profiles appropriate for pharmaceuticals and dietary supplements, we use hydro-ethanolic extraction.
Q: Is it possible to alter the concentration of naringin?
