The Extract Factory is a leading manufacturer and bulk supplier of premium Houttuynia Extract in China, specializing in high-purity botanical raw materials for the global dietary supplement, cosmeceutical, and functional food industries. We deliver wholesale quantities of standardized plant extracts at competitive factory-direct pricing, backed by complete traceability from agricultural sourcing to finished ingredient.
Our Houttuynia Extract is produced from the whole herb of Houttuynia cordata Thunb., a perennial botanical revered in traditional medicine systems across East Asia. Through advanced extraction and concentration technologies, we preserve and standardize the plant’s key bioactive principles—most notably houttuynin (decanoyl acetaldehyde)—into a versatile, water-soluble powder engineered for demanding industrial formulations.
Product Overview & Botanical Profile
Houttuynia cordata, commonly known as Heartleaf or Yu Xing Cao, flourishes in the moist, subtropical hillside environments of central and southern China. We partner with established agricultural cooperatives in these prime growing regions to secure raw herbs cultivated under environmentally conscious protocols. By controlling cultivation practices and harvesting schedules, we ensure that plant material reaches peak phytochemical maturity before processing.
The whole herb—including aerial portions and rhizomes—is carefully harvested, cleaned, and dried under shaded, low-temperature conditions to protect heat-sensitive volatile oils. This holistic sourcing strategy captures a broad spectrum of naturally occurring flavonoids, polyphenols, and essential oils alongside our primary marker compound, houttuynin, delivering full-plant synergy in every batch.
Active Constituents & Standardization
The commercial and therapeutic value of Houttuynia Extract centers on its unique phytochemical fingerprint. The principal bioactive constituent, houttuynin, is an aldehydic compound studied for its potent antimicrobial, anti-inflammatory, and immuno-modulatory characteristics. Our extract is rigorously assayed by High-Performance Liquid Chromatography (HPLC) to guarantee a minimum of 4% houttuynin, with typical production lots testing at 4.2%—ensuring label accuracy and predictable performance in your finished products.
Secondary metabolites, including quercetrin, isoquercitrin, and related volatile fractions, contribute to the extract’s functional breadth and support synergistic activity across supplement, cosmetic, and beverage matrices.
Technical Specifications & Physical Properties
For formulators and procurement teams, understanding the physicochemical behavior of raw ingredients is essential for scale-up success. Our Houttuynia Extract is characterized as follows:
| Parameter | Specification |

| Yeast & Mold | ≤100 cfu/g | 10 cfu/g | USP <2021> |
| E. coli | Negative | Negative | USP <2022> |
| Salmonella | Negative | Negative | USP <2022> |
| Solubility | Soluble in water | Soluble in water | Visual Inspection |
Our contaminant control protocols confirm that this Houttuynia Extract is free from unsafe levels of heavy metals, pathogenic microorganisms, and pesticide residues. This level of documented compliance is essential for export documentation, regulatory submissions, and premium product positioning in regulated markets.
Extraction Process & Manufacturing Excellence
We utilize modern, closed-loop extraction equipment employing purified water and food-grade ethanol under precisely controlled temperature and pressure profiles. This approach maximizes the recovery of sensitive houttuynin while minimizing the co-extraction of extraneous plant matrix and chlorophyll. Subsequent processing includes multi-stage filtration, vacuum concentration, spray drying, and standardized blending to achieve the target 10:1 concentration and 4% active constituent level.
Production takes place within a GMP-compliant environment. Our standard Houttuynia Extract is manufactured without artificial carriers, synthetic preservatives, or chemical additives, delivering a clean-label botanical ingredient that aligns with evolving consumer preferences for transparency and minimal processing.
