Products Description

What is Astragalus Extract?
Astragalus Extract powder is a herbal extract extracted from the roots of the leguminous plant Astragalus membranaceus. It is a commonly used plant extract in traditional medicine and modern nutraceuticals due to its beneficial health properties. The extract is obtained through various extraction methods such as water extraction, ethanol extraction, and supercritical fluid extraction.
Astragalus has been used in traditional Chinese medicine (TCM) for over 2,000 years to treat a variety of conditions. It is also an important ingredient in many traditional Chinese medicine formulas, such as tonics, teas and soups. Astragalus is traditionally used to increase energy, improve digestion, and strengthen the immune system. Additionally, it has been used to enhance athletic performance and extend lifespan.
It is currently used in traditional medicine across Asia, including China, Korea, Japan and Mongolia. It is thought to have immunomodulatory, anti-inflammatory, antioxidant and anti-cancer effects. Traditional medicine practitioners use astragalus to treat respiratory infections, heart disease, diabetes, kidney disease, and allergies.

The pharmacological activities of astragalus polysaccharides have been extensively studied. They exert immunomodulatory effects by stimulating the proliferation and activation of immune cells such as T cells, B cells, and natural killer cells. APS also has antioxidant properties that help scavenge free radicals and protect cells from oxidative damage. In addition, they have anti-inflammatory effects and can inhibit the production of pro-inflammatory cytokines.
3.Astragalus polysaccharides have potential benefits, including:
- Strengthen the immune system and improve immune function.
- Prevents liver damage and promotes liver health.
- Supports cardiovascular health by lowering blood pressure and preventing atherosclerosis.
- It exerts anti-tumor effects by inhibiting cancer cell growth and promoting cell apoptosis.
- Anti-aging by reducing oxidative stress and protecting cell function.

B. Astragaloside
- Chemical composition and classification:
Astragaloside IV is a class of bioactive compounds found in Astragalus membranaceus extract powder. They belong to the saponin family and are triterpene glycosides. Astragalus contains a variety of astragaloside IV, including astragaloside I, II, III, IV, cycloastragaloside, etc.
2.Biological Properties and Therapeutic Applications:

The presence of these bioactive components in astragalus extract powder contributes to its medicinal and therapeutic properties, making it a valuable botanical extract in the botanical extract industry.
Extraction method of astragalus
A. Traditional extraction methods
- Hot water extraction:
Hot water extraction, also known as decoction, is a traditional method for extracting bioactive compounds from herbs such as Astragalus membranaceus. In this process, dried astragalus root or powder is boiled in water to release its water-soluble components, including polysaccharides and flavonoids. The mixture is heated at high temperatures for a specific time to dissolve the active compounds into the water. After extraction, the liquid is concentrated and dried to obtain extract powder.
- Ethanol extraction:
Ethanol extraction is another traditional method that involves the extraction of water- and alcohol-soluble compounds from Astragalus using ethanol or a mixture of water and ethanol. Dry plant material is soaked in a solvent, and the mixture is heated or macerated for a period to extract the bioactive components. Once the extraction is complete, the solvent is evaporated leaving a concentrated extract, which is subsequently dried to produce the final extract powder.

B. Modern Extraction Technology
- Supercritical fluid extraction:
With the advancement of research and production technology, our company adopts modern extraction technologies such as supercritical fluid extraction (SFE) to improve the efficiency and quality of astragalus extraction powder. Supercritical fluid extraction uses carbon dioxide (CO2) as a solvent to achieve optimal extraction of target compounds under specific temperature and pressure conditions. In this method, carbon dioxide is converted into a supercritical state, exhibiting properties of both a liquid and a gas, allowing it to effectively penetrate plant material and extract the desired components without leaving solvent residue. This gentle process helps preserve heat-sensitive bioactive molecules, resulting in high-quality extracts with minimal degradation.
- Microwave-assisted extraction:
Microwave-assisted extraction (MAE) is a fast and effective method implemented by our company to improve the extraction process. In this technique, astragalus material is mixed with a suitable solvent in a microwave reactor and the mixture is exposed to microwave radiation. Microwaves generate internal heat within the plant matrix, promoting the release of bioactive compounds by disrupting cell walls and enhancing mass transfer. This accelerated extraction process reduces extraction time and energy consumption while maintaining the integrity of heat-sensitive compounds, thereby improving overall extraction efficiency and product quality.
- Ultrasound-assisted extraction:
Our company has also integrated ultrasound-assisted extraction (UAE) as a cutting-edge technology for extracting the bioactive components of Astragalus membranaceus. The method involves the application of high-frequency ultrasound to the extraction solvent and plant material, causing the formation and collapse of tiny bubbles in the solvent. This phenomenon, known as cavitation, creates intense localized heating, pressure differentials and micromixing, which enhances mass transfer and disrupts cell structure, promoting efficient release of target compounds. Ultrasound-assisted extraction shortens the extraction time, reduces solvent consumption, and improves the extraction rate and purity of Astragalus membranaceus.
By employing these modern extraction technologies, our company has significantly improved the efficiency, sustainability and quality of astragalus extract production, keeping in line with the latest advances in research and development in the botanical extraction industry.
