HPLC:

What Are The Extraction Methods of Sophora Japonica Extract Powder?

There are many methods of extract sophora Japonica.We usually two methods as following.

● Solvent extraction:

This method involves the use of organic solvents. Such as ethanol, methanol, or ethyl acetate. It extract the bioactive compounds from the dried plant material. The extracted solution is then evaporated to obtain a concentrated extract.

This method of Sophora Japonica Extract Powder is simple, cost-effective, and yields a high amount of extract. However, it requires a longer extraction time and may result in the contamination of the extract with residual solvents.

 

● SFE:

Guanjie Biotech use this method. carbon dioxide is used as a solvent at high pressures and temperatures to extract the bioactive compounds.

The resulting extract is pure, free from residual solvents, and has a longer shelf life. However, the equipment used for SFE is expensive, and it may not be suitable for extracting compounds that require high temperatures or pressures.

 

● MAE:

This method uses microwave radiation to heat the plant material and extract the bioactive compounds.

MAE is relatively faster than other methods and requires small amounts of solvents. Thus reducing environmental pollution. However, MAE equipment is expensive, and the Sophora Japonica Extract Powder may be affected by microwave radiation.

 

● Ultrasonic-assisted extraction:

This is another method that Guanjie Biotech uses. The plant material is exposed to ultrasonic waves in a solvent, which causes disruption of plant cell walls and enhances the extraction of bioactive compounds.

 

This method is fast, efficient, and produces high-quality extracts. However, the equipment used for UAE is expensive, and the extract may be affected by the intensity and frequency of ultrasonic waves.

 

What Are The Properties of Sophora Japonica Extract Powder?

Sophora japonica extract powder is a widely used botanical ingredient in the food, nutraceutical, cosmetic, and pharmaceutical industries due to its excellent functional properties and stable physical characteristics. Derived from the flower buds or fruits of Sophora japonica, this extract is especially valued for its rich flavonoid content, particularly rutin and quercetin. Understanding its core properties is essential for manufacturers, formulators, and buyers when selecting suitable raw materials for product development.

● Solubility
One of the most important properties of Sophora japonica extract powder is its solubility. The powder generally shows good solubility in water, ethanol, and methanol, which makes it highly versatile for different formulation systems. Its water solubility allows it to be conveniently used in beverages, liquid supplements, and water-based cosmetic products. Meanwhile, its compatibility with ethanol and methanol makes it suitable for further extraction, concentration, and use in tinctures or pharmaceutical preparations.

● pH Level
The pH value of a 10% Sophora japonica extract solution typically ranges from 5.0 to 7.0, which is considered mildly acidic to neutral. This balanced pH range contributes to its broad compatibility with various formulations, especially in skincare, dietary supplements, and functional food applications. A near-neutral pH also helps maintain the stability of the active flavonoid compounds during use.

● Moisture Content
The moisture content of Sophora japonica extract powder is usually kept below 5%, which is an important quality indicator. Low moisture content helps improve shelf stability, prevents clumping, and reduces the risk of microbial growth during storage and transportation. For industrial applications, maintaining low moisture is essential to ensure consistent powder flowability and product performance.

● Density
The density of Sophora japonica extract powder may vary depending on the extraction concentration, particle size, and manufacturing process. In most cases, the bulk density is approximately 1.0 g/mL, although slight variations may occur between suppliers. Density plays an important role in packaging efficiency, dosage calculation, and blending with other powdered ingredients.

● Stability
Sophora japonica extract powder exhibits excellent stability under normal storage conditions. When stored in a cool, dry place away from direct sunlight and moisture, it does not degrade easily and can maintain its active ingredient content for an extended period. This stability makes it a reliable raw material for long-term industrial use and global export supply chains.

 

What Is The Chemical Composition of Sophora Japonica Extract Powder?

● Flavonoids and Saponins:

Rutin is the major active ingredient of Sophora japonica. Flavonoid aglycones such as quercetin, kaempferol, isoflavone aglycone genistein, sophoramethin, etc., have been isolated from flowers and flower buds. Saponins are found in the dried buds of Sophora japonica, and betulin and sophodiol are separated after acid hydrolysis. Glucose and glucuronic acid are detected in the hydrolyzed solution by paper chromatography. Sophora saponins can be separated from the extract of Sophora japonica, which is percolated with ethanol and then extracted with n-butanol.

 

● Fatty Acids:

Sophora Japonica Extract Powder contains 19 types of fatty acids, including palmitic acid, dibutyl phthalic acid, stearic acid, linoleic acid and linolenic acid. Odd-numbered carbon fatty acids such as pentadecanoic acid, pearlescent fatty acid, behenic acid, cerotic acid, behenic acid, and pentapentacic acid are found in Sophora japonica and Sophora japonica. These are rare in natural products and possess strong physiological activities. It is worth studying if they are related to the pharmacological activities of Sophora japonica and Sophora japonica.

 

● Others:

Sophora japonica is rich in protein, multivitamins, and minerals, and has high edible value. Eugenol, benzyl alcohol, geranyl acetate, linalool, and other substances are found in the essential oil of Sophora japonica. Ethanol concentration is a critical factor in determining the content of total phenols and total flavonoids in Sophora japonica extract.
