Xi'an DN Biology Co., Ltd. is pleased to provide us pharmaceutical-grade Horsetail Extract Powder from the highest quality Equisetum arvense L. Our plant processes up to 3,000 tons of botanical raw materials each year, with the state-of-the-art extraction system consisting of 4 extraction tanks (6 m3 each) and 3 integrated concentration units.
This product has standardized organo-silica content in the range of 1-7% (UV tested) in the ratio of 10:1 concentration as verified by TLC. Founded in 2010, with more than 10 years’ production experience, we offer brown-yellow fine powder (80 mesh) that exceeds stringent loss on drying (≤5%) and heavy metal (≤10ppm) specifications. Our ISO 9001, GMP, HACCP, Kosher, and Halal certifications guarantee continuous quality you can rely on.
Excellence in Standardized Botanical
Our extract is not just ground plant stuff. It’s a concentrated botanical extract packed with organic silica (orthosilicic acid) — the most accessible form of silicon your body understands.
Our solution offers natural collagen building support, not synthetic silicon chemicals. The silica acts in synergy with the bio-active flavonoids, such as quercetin and kaempferol, which you do not get when the ingredients are isolated.
We have solved a big industrial problem: how to provide stable, standardized mineral-rich plant extracts that maintain their potency throughout the shelf life.
Enterprise-Grade Quality Assurance
Every batch is tested thoroughly by our independent laboratory with HPLC, GC, TLC and UV-Vis spectrophotometry. Support for third-party testing and free pre-shipment samples to verify specifications before committing to full orders.
Our microbiological standards provide overall plate counts of ≤1000cfu/g so your finished products comply with the tightest regulatory requirements in worldwide markets.
