Xi'an DN Biology offers standardized plant extracts that are backed by more than ten years of excellent production. Our Saw Palmetto Extract Powder has 45% fatty acids that have been tested and proven to be effective by GC analysis.
With 4 extraction vessels (6 m³ each) and a processing capacity of 3,000 tons per year, we can guarantee stable supply and quality. We make sure that every batch meets the standards for ISO 9001, GMP, HACCP, Kosher, and Halal. When compared to other extracts, our 10:1 concentration ratio from Serenoa repens L. gives better bioavailability.
We keep up to 100 tons of stock ready to ship right away or within 7 days. Your formula needs to be made by a vertically integrated company that can be fully tracked from our specialized planting base to your warehouse.
Our Saw Palmetto Extract goes through a lot of tests to make sure it meets the standards set by the International Pharmacopoeia:
| Parameter | Specification |
|---|---|
| Latin Name | Serenoa repens L. |
| Active Ingredient | Fatty Acids (45% by GC) |
| Extraction Ratio | 10:1 (TLC verified) |
| Appearance | White Fine Powder |
| Mesh Size | 80 mesh |
| Loss on Drying | ≤5% |
| Heavy Metals | ≤10 ppm |
| Microbial Count | ≤1,000 cfu/g |
| Solubility | Water-soluble |
| Storage Conditions | Cool, dry place; avoid light |
This normal fatty acid profile has the right amounts of Lauric, Myristic, and Oleic acids. Our GC-FID analysis proves that the product is real and stops cheaper vegetable oils from being added.
To keep bioactive compounds safe, we use pharmaceutical-grade extraction technology. There are four important steps in our process: decolorization, vacuum drying, spray drying, and stacking.
The first step in the extraction is using real Serenoa repens berries. Our three built-in concentration systems keep temperatures under control to protect phytosterols like Beta-Sitosterol that are sensitive to heat. DNA barcoding is used on each batch to make sure the species is real.
During production, quality checks keep an eye on the Peroxide Value and the Acid Value. This keeps the lipid parts stable and stops them from going rancid. You get powder that flows better and is best for filling capsules and making tablets.
Our range of bulk densities, from 0.4 to 0.60 g/ml, keeps hoppers from getting clogged up during high-speed production. The fine particle distribution (95% through 80 mesh) makes sure that your homogenizers mix everything evenly.
Research shows that your end users will benefit in many ways. Studies show that lowering oxidative stress in reproductive organs can increase the number of sperm, make them move more easily, and change their shape.
There are a lot of free radical-fighting flavonoids and saponins in the extract. This helps cells stay healthy and lowers oxidative stress in muscles. 5-alpha-reductase Types I and II are effectively blocked by fatty acid components, which stop testosterone from turning into DHT.
Most Important Uses:
Non-GMO, gluten-free ingredients that are good for vegan and sport-certified products help your formulations. When making tablets, "oil-leaking" problems are typical with liquid extracts. The Saw palmetto Extract Powder format gets rid of these problems.

Xi'an DN Biology follows a number of different international quality management systems. For full testing, our independent lab has HPLC, GC, TLC, a UV-Vis Spectrophotometer, and moisture analyzers.
Certified Standards:
Each batch comes with a Certificate of Analysis that was tested by a third party. You can check the quality of our products before you place large orders by getting free samples before they are shipped. From the field to the finished product, our full-chain traceability system keeps track of the raw materials.
Heavy metal tests show that the amount of lead is less than 3 parts per million. According to USP/EP guidelines, microbiological screening makes sure that Salmonella and E.Coli test negative.

We keep a lot of inventory on hand and have 100-ton storage space available for immediate fulfillment. Orders of less than 1 kg are shipped within two to three business days. Standard bulk orders (25 kg drums) are sent out within 3–5 business days.
Flexibility in manufacturing:
Our supply system is very well connected and goes straight to the cultivation bases. This vertical integration makes sure that the quality of the raw materials stays the same and that the prices are fair. The lead time for making custom formulations is only 7–10 working days.
We offer DDP shipping services with a number of different ways to get your package to you. Our skilled export team takes care of the paperwork and coordinates the shipping. You are welcome to schedule inspections of our factory to make sure we can do what you need.
Q: How do you keep the goods from being tampered with?
A: We use several ways to prove who you are, such as GC-FID fatty acid profiling, DNA barcoding, and phytosterol quantification. Our thorough testing shows that the amounts of Lauric, Myristic, and Oleic acids are the same as they are in natural Serenoa repens. Any deviation from the limits set by USP leads to batch rejection.
Q: What is your minimum order size and how long does the wait time usually take?
A: The MOQ for testing is just 1 kg. Small orders ship within two to three working days, and standard 25 kg drums ship within five to seven working days. For custom formulations, production takes 7–10 business days.
Q: Can your Saw Palmetto Extract be used in vegan capsules?
A: Of course. Our powder comes from plants only, has no GMOs, and is gluten-free. It works with vegetarian capsules and meets the standards for supplement formulations that are approved for sports use.
Q: What's the difference between powder form and oil extracts?
A: Powder is more stable and has a lower risk of going bad. During high-speed tableting, the free-flowing texture keeps the tools from getting clogged. Bioavailability is higher in water-soluble formulations than in lipophilic oils.
Q: What kinds of paperwork do you include with shipments?
A: Each order comes with a Certificate of Analysis, sheets of specifications, and compliance certificates (Kosher, Halal, or organic if asked for). We help with third-party testing and give you Material Safety Data Sheets for filing with regulators.
