Lespedeza Extract

Premium Lespedeza Extract – Professional Botanical Solutions by Shaanxi Hongda Phytochemistry

Our innovative extraction technique, 20,000 square meters of contemporary manufacturing facilities and professor-led R&D teams enable us to manufacture standardised botanical extracts that regularly meet international quality standards. We are a cGMP, FSSC22000, ISO22000, HALAL and KOSHER compliant facility and we can give you total supply chain transparency from our owned planting bases to the final product delivery. Our Lespedeza Extract is also a potassium-sparing renal support ingredient tested by a third party. This means that your formulations will not only be able to compete in competitive markets, but also fulfil the highest regulatory standards in North America, Europe and Asia.

Product Introduction

OurLespedeza Powder is obtained from the selected aerial parts of Lespedeza capitata using exclusive water-ethanol extraction processes that maintain the natural flavonoid profile of the plant, including lespedin, quercetin and kampferol. This fine powder brown-yellow has high water solubility and heat stability, which is suited for capsule encapsulation, tablets compression and liquid suspension formulations. Our extract is standardised to contain 10:1 concentration ratio or 25% total flavonoids by HPLC measurement, providing consistent bioactivity across production batches. The hygroscopic powder is passed through 80-mesh sieves to ensure consistent particle dispersion for your production needs while providing the kidney protecting and blood urea nitrogen lowering features your clients are looking for in premium renal health supplements.

Third-Party Test Report

SGS Testing Partnership: We collaborate with SGS laboratories to conduct comprehensive pesticide residue screening covering over 500 compounds, ensuring compliance with EU regulations (MRL <0.01ppm) and USDA organic standards.

Heavy Metal Analysis: Our goods regularly test to Lead <1.0ppm, Arsenic <0.5ppm, Cadmium <0.3ppm and Mercury <0.05ppm with Eurofins certified reports, above Proposition 65 safety tolerances.

Microbiological Safety: Third party validated total plate count <500cfu/g, yeast/mold <100cfu/g and Salmonella, E.coli, Staphylococcus aureus absent in each batch of manufacturing.

Lespedeza Specification

Lespedeza Extract Advantages

Potassium-Sparing Action: Conventional diuretics can deplete vital electrolytes, however our extract helps to preserve fluid balance and retain potassium levels – a key formulation obstacle for long-term renal support treatments.

Dual-Action Cardiovascular Support: The standardised flavonoid profile functions as both an ACE activity inhibitor and a capillary permeability reducer, delivering your formulations the benefits of blood pressure regulation and vascular protection in a single botanical ingredient.

Superior Solubility Profile: Excellent water dispersion characteristics (pH stable 4.0-7.0) simplify formulation development for liquid supplements, functional beverages, and aqueous delivery systems without precipitation concerns.

Lespedeza Extract Application

Renal Health Supplements: Primarily used in kidney detoxification formulae and solutions for chronic kidney disease management, where the extract's capacity to lower blood urea nitrogen levels offers substantial clinical benefits to both the human and veterinary markets.

Sports Nutrition Formulations: Applied in cutting phase supplements and vascular definition products for bodybuilders and athletes to allow for natural water weight management without the muscular cramping effects of potassium-depleting diuretics.

Cardiovascular Support Products: Incorporated into blends for hypertension control and vascular health with proanthocyanidin level and ACE-inhibitor activity synergistic with other components for broad spectrum cardiovascular support.

Production Process

Step 1 – Raw Material Selection: Collect aerial parts of Lespedeza capitata at the peak phases of flavonoid accumulation from our certified planting bases, with baseline total flavonoid content >3% in dried biomass.

Step 2 – Cleaning and Preparation: Automated systems wash botanical materials eliminating soil and contaminants and then controlled temperature (≤60°C) dehydration to dry and preserve thermolabile flavonoid components.

Step 3 – Extraction Operation: Perform water-ethanol counter-current extraction in stainless steel vessels at optimised temperature and solvent ratios to maximise lespedin and quercetin transfer rates and minimise tannin co-extraction.

Step 4 – Concentration and Purification: The crude extract is next filtered via membrane systems and concentrated under vacuum at reduced temperature. The resulting standardised liquid concentrate meets the 25% flavonoid criteria.

Step 5 – Spray Drying: The concentrated extract is atomised in 100,000 level purification workshop with pharmaceutical grade maltodextrin as carrier to make fine powder with regulated particle size distribution and moisture content below 5%.

Step 6 – Quality Testing and Packaging: Conduct full COA testing for each lot with HPLC fingerprinting, and package in double-layer PE bags inside of fibre drums with controlled humidity to ensure 24 months shelf life.

FAQ

Q: What makes your product different from other suppliers?

A: We control the entire supply chain from verified planting bases to final packaging, with certification of botanical authenticity and standardised flavonoid profiles. Our HPLC fingerprinting guarantees the sourcing of authentic Lespedeza capitata and prevents the species adulteration common in commodity grade extracts.

Q: Can you supply organic certified material?

A: Yes, we maintain both EU and NOP organic certifications. Organic lots require a 45 day lead time due to the cleaning methods for the dedicated production line and the additional documentation required.

Q : What is the minimum order with you ?

A: Our standard MOQ is 25kg (one drum), but we offer 100g-1kg samples for initial formulation development and stability testing at competitive evaluation pricing.
