View Technical Data SheetAs a parasitic seed of the Convolvulaceae family, Cuscuta chinensis Lam. (known classically in Traditional Chinese Medicine as "Tu Si Zi") has served as a cornerstone herb for kidney tonification and reproductive vitality for centuries. Today, modern clinical studies and phytochemistry have unraveled the molecular mechanisms driving its multi-tiered pharmacological benefits.
Cuscuta Seed Extract is characterized by its high concentrations of bioactive flavonoids (including hyperoside, quercetin, and kaempferol), lignans, polysaccharides, and alkaloids. These active constituents exhibit potent free-radical scavenging properties, stimulate steroidogenesis, upregulate the expression of key enzymatic pathways in testosterone biosynthesis, and modulate the hypothalamic-pituitary-gonadal (HPG) axis. This makes it a highly sought-after raw material in male reproductive wellness formulations, sports nutrition, and longevity dietary supplements.
Shaanxi ShineHerb Biotech Co., Ltd. employs state-of-the-art solid-liquid extraction coupled with macroporous resin column chromatography to concentrate these active molecules. By standardizing our Cuscuta Seed Extract to specific flavonoid percentages (e.g., 2% to 10% by HPLC), we ensure batch-to-batch chemical profile consistency, satisfying the rigorous demands of global supplement manufacturers and pharmaceutical companies.

Xi'an, Shaanxi Province, stands as the global epicenter for botanical extraction technologies. Sourcing Cuscuta Seed Extract directly from local manufacturers like ShineHerb Biotech delivers distinct supply chain benefits.
Shaanxi Province sits adjacent to the Qinling Mountains, a region hosting thousands of medicinal herbs. We partner directly with agricultural cooperatives that practice Good Agricultural and Collection Practices (GACP) to cultivate Cuscuta chinensis. This ensures we control the plant's growth conditions, preventing trace pesticide cross-contamination from neighboring crops.
Our facility houses massive industrial-scale counter-current extraction units, continuous vacuum evaporation systems, and modern spray-drying towers. This high level of industrial integration lowers per-kilogram utility and manufacturing costs, a benefit we pass directly to global supplement brands through highly competitive bulk pricing.
Chinese plant extractors have transitioned from simple workshops to world-class biotech enterprises. ShineHerb Biotech maintains a robust quality management system certified under ISO9001, HACCP, GMP, Kosher, Halal, and FDA registrations, providing our customers with full traceability, documentation packages, and complete audibility.

Quality is the lifeblood of Shaanxi ShineHerb Biotech Co., Ltd. Our quality control department is equipped with high-performance liquid chromatography (HPLC-DAD), gas chromatography (GC-MS), atomic absorption spectrophotometry (AAS), and high-performance thin-layer chromatography (HPTLC) systems. For every single batch of Cuscuta Seed Extract, we perform rigorous tests covering active constituent profiles, heavy metals, microbial limits, and pesticide residues.
We supply full certificate analysis reports (COA) for every shipment, providing our clients with complete peace of mind when submitting their finished supplement dossiers to food safety authorities in the US, EU, and Asian markets.
Our scientific team offers more than raw materials; we provide product design solutions. Whether you are formulating a capsule, tablet, powder blend, or functional gummy, our team advises on active ingredient compatibility, optimal dosage ranges, and bioavailability enhancers. We assist in overcoming common extraction issues such as hygroscopicity, poor water solubility, and strong sensory profiles, delivering a raw material ready for seamless plant-floor processing.
Our production facilities operate strictly in compliance with Good Manufacturing Practice (GMP) standards. Raw herbal inputs undergo thorough identity validation, cleaning, and dry-milling in clean zones. Extraction and crystallization phases occur in controlled-atmosphere clean rooms (Grade D / ISO Class 8 equivalent) to eliminate physical, chemical, and microbiological cross-contamination, ensuring absolute product purity.
Cuscuta Seed Extract's biological properties offer high versatility across various finished product types.
Located in the High-Tech Zone of Xi'an, Shaanxi Province, Shaanxi ShineHerb Biotech Co., Ltd. is a professional, technology-driven enterprise specializing in the research, development, production, and exporting of Enzyme preparations, Natural plant extracts, Vitamins, Amino acids, and Pharmaceutical intermediates.

Partner with ShineHerb Biotech to launch high-quality, market-ready supplements quickly and efficiently.
Stay ahead of market shifts by understanding the key drivers in the botanical extract supply chain.
Global brands are transitioning away from simple ratio-based extracts (e.g., 10:1) to standardized active marker percentages (such as HPLC-standardized total flavonoids and hyperosides). Standardized actives ensure consistent dosing and efficacy in clinical trials and commercial formulations.
Clean label requirements mandate extraction processes that avoid harsh petrochemical solvents. ShineHerb Biotech meets this demand by using green extraction technologies, utilizing only food-grade ethanol and pure water to deliver clean, residue-free botanical ingredients.
Modern consumers prefer functional dosage formats over conventional pills. Our R&D team supports this shift by manufacturing dispersible powders, premium soft chewables, and functional gummies designed to enhance compliance and appeal to younger demographics.
Delivering high-purity botanical raw materials requires reliable logistics. We support a range of shipping methods to match your operational requirements:

We standardize our Cuscuta Seed Extract using High-Performance Liquid Chromatography (HPLC) to measure total flavonoids, expressed as Hyperoside. While standard ratio extracts (e.g., 10:1) are available, we recommend standardization to 3% to 10% flavonoids for clinical-grade formulations to ensure batch-to-batch consistency.
Because Cuscuta is a parasitic plant that climbs on host crops, it can easily absorb pesticides used on the host. To control this, we source only from GACP-compliant cultivation bases where the host crops are grown without synthetic chemical sprays. Every batch of our extract is tested using LC-MS/MS to ensure compliance with USP <561> and EP multi-residue pesticide limits.
We use only food-grade ethanol and pure water as extraction solvents. The ratio is adjusted depending on the target flavonoid profile. The final vacuum drying and spray-drying phases reduce residual solvents to well below the limits specified in USP <467> and EP guidelines.
Our heavy metal limits meet the strict requirements of California Proposition 65 and FDA dietary supplement guidelines. Using ICP-MS, we verify that Lead (Pb) is under 2.0 ppm, Arsenic (As) is under 1.0 ppm, Cadmium (Cd) is under 0.5 ppm, and Mercury (Hg) is under 0.1 ppm.
The standard shelf life is 24 months from the date of manufacture when stored in the original unopened packaging. It should be kept in a cool, dry area away from direct sunlight and strong odors. Because botanical extracts are naturally hygroscopic, reseal bags tightly after opening to prevent moisture absorption.
Yes, we can customize the particle size to suit your production setup. Our standard powder is 80 mesh, but we can mill it to 100 or 120 mesh for fine drink mixes, or granulate it for direct-compression tableting or high-speed encapsulation.
