Sophoricoside Extract
Sophoricoside extract is a natural active ingredient isolated from the leguminous plant Sophora japonica L., belonging to the isoflavone family. As a professional supplier of plant extract powders, Kintainutri® offers a wide range of sophoricoside extract powders, containing over 98% of the active ingredients, to meet diverse application needs. This product is a pale yellow to off-white fine powder with no noticeable odor and excellent solubility, allowing for uniform addition to a wide range of products.
Sophoricoside extract exhibits excellent antioxidant and anti-inflammatory properties, as well as regulating metabolism. In health supplements, it can contribute to immune-boosting and anti-aging products. In cosmetics, it can inhibit melanin production, improve skin dullness, and soothe skin sensitivity, making it a high-quality ingredient in natural skincare formulations. Kintainutri® has been deeply engaged in the field of plant extracts for many years, always focusing on "natural, effective, and safe".
Relying on advanced extraction technology and a strict quality control system, it ensures that each batch of sophoricoside extract powder meets international standards, providing stable, reliable products and professional service support to global customers.

Contact us Sophoricoside Extract Production Process
Kintainutri® adheres to the principles of "source control, meticulous extraction, and precise purification" throughout the production of sophoricoside extract. Relying on standardized production lines and intelligent equipment, we ensure high quality at every step. First, we screen raw materials. We select high-quality, pest-free, and disease-free sophora japonica buds. Through manual and instrumental testing, we eliminate impurities and substandard raw materials to ensure the baseline content and purity of the active ingredients, laying the foundation for product quality from the source.
Next, we utilize an advanced ultrasound-assisted ethanol extraction process. Compared to traditional extraction methods, this process more effectively disrupts the cell walls of the sophora japonica buds, promoting the dissolution of the active ingredient sophoricoside while avoiding the structural damage caused by high temperatures. This increases extraction yield by over 15% compared to traditional methods, reduces solvent usage, and lowers environmental handling costs.
Temperature, pH, and extraction time are monitored throughout the extraction process to ensure consistent concentration and ingredient stability for each batch of extract. Next comes the purification and refining stage. The extract undergoes plate and frame filtration to remove large molecular impurities. It then undergoes macroporous resin adsorption separation technology to precisely adsorb the sophoricoside component while removing ineffective impurities such as sugars and tannins.
Multiple elutions and tests are performed during this stage to control the eluate concentration and ensure that the purity of the sophoricoside is gradually increased to the target specification (up to 98% or above). The purified solution undergoes precision filtration to further remove fine particles and ensure the fineness of the subsequent product.
Finally, the drying and final product processing stage utilizes low-temperature spray drying technology to atomize and dry the purified solution into a powder at a temperature of 60-70°C. This maximizes the activity of the sophoricoside and produces a light yellow to off-white fine powder with excellent flowability and solubility.
The dried product undergoes multiple quality control processes, including particle size screening to ensure uniform particle size, microbiological testing (meeting food and cosmetic standards), and content verification. Only after passing these tests can it be packaged and stored. Throughout the entire process, the production traceability system provides access to process parameters and quality inspection reports for each batch, ensuring controllable and traceable product quality.

Sophoricoside Extract Application
Kintainutri® Sophoricoside Extract Powder, with its high solubility, easy dispersion, and precise dosage control, demonstrates enhanced adaptability in product development across multiple sectors. It can be easily integrated into various production processes, reducing formulation development and production complexity for customers.
In the health supplement sector, its powder form makes it a versatile ingredient for diverse dosage forms. It can be directly used for tableting or capsule filling, for example, in combination with probiotics or calcium supplements to produce "antioxidant + intestinal health" combination tablets. Its high powder uniformity prevents spotting and uneven content in tablets. It can also be added to solid beverages and meal replacement powders.
It dissolves quickly in cold water without precipitation or clumping, maintaining the taste and appearance of the beverage. This makes it particularly suitable for developing portable "daily antioxidant powders" to meet consumers' needs for instant nutritional supplements. Kintainutri® powders offer customizable particle sizes (80-120 mesh) to precisely meet the production requirements of different health supplement dosage forms.
In the cosmetics sector, the fine powder form solves the problems of liquid extracts that often cause segregation and storage difficulties. It can be directly compounded into whitening serum powders and solid facial mask powders, activated by adding water during use. This maximizes the activity of sophoricoside and avoids the need for preservatives. It can also be mixed into creams and lotions. The powder disperses easily and is compatible with both oil and water systems, preventing graininess and ensuring a smooth, delicate feel upon application. For example, in a natural whitening and blemish-removing cream, the powder distributes evenly, ensuring sufficient active ingredients reach every application, enhancing skincare effectiveness.
In food processing, the powder form facilitates industrial batch addition. In baked goods, it can be directly mixed with ingredients such as flour and sugar. It retains some antioxidant activity during high-temperature baking, effectively delaying oxidative spoilage in pastries and bread, extending shelf life. In breakfast cereal production, it can be evenly applied to cereals and crisps using a spray-mixing process, enhancing product functionality without requiring additional production line adjustments, aligning with the market trend toward "healthy snacks."
This product complies with the GB 2760 standard for food additives and has undergone multiple safety tests. In the field of feed additives, the powdered form is compatible with conventional feed pelleting and mixing processes. It can be fully mixed with basic feed ingredients like corn and soybean meal, or made into premixes, allowing farming companies to adjust the dosage according to the growth stage of different livestock (such as chickens, pigs, and cattle). Powders are less prone to moisture absorption and agglomeration, making them more stable during storage and transportation, thus preventing feed waste caused by raw material deterioration. Adding powder to feed not only enhances livestock immunity but also reduces oxidative loss during storage, reducing costs and increasing efficiency in the farming process.

Why Choose Kintainutri® Sophoricoside Extract?
Kintainutri® sources high-quality Sophora japonica root from the source, selecting only mature Sophora japonica root grown for at least three years in the prime producing area between 35° and 40° north latitude. HPLC (High Performance Liquid Chromatography) testing ensures an initial sophoricoside content of ≥5%, eliminating the risk of inferior raw materials.
The production process utilizes a fully closed-loop "extraction-purification-drying" process. Each batch of product undergoes 38 rigorous tests (including those for heavy metals, microorganisms, and pesticide residues), and is accompanied by a third-party authoritative test report. This ensures a stable sophoricoside content of 90%-98%, a purity far exceeding the industry average, allowing downstream customers to directly incorporate it into their high-end product formulations without additional screening.
Kintainutri® offers flexible customization services to meet the diverse needs of customers in various fields.
