Astragalus Extract

Synonyms: Astragalus membranaceus Extract, Huang Qi Extract, Astragalus Root Extract, Astragalus Polysaccharides, Milkvetch Root Extract, Astragalus mongholicus Extract, Radix Astragali Extract

Astragalus Extract is a standardized botanical concentrate derived from the dried root of Astragalus membranaceus (also known as Astragalus mongholicus), a perennial herb widely used in Traditional Chinese Medicine (TCM) for thousands of years. It is commonly referred to as Huang Qi and is one of the most important adaptogenic herbs in TCM.

The primary bioactive components of Astragalus Extract are:

• Polysaccharides: High molecular weight β-glucans and heteropolysaccharides with immunomodulatory activity.

• Astragalosides: Triterpenoid saponins, particularly Astragaloside IV, which is the key active marker and is hydrolyzed to cycloastragenol (a telomerase activator).

• Flavonoids: Calycosin, formononetin, and other isoflavonoids with antioxidant properties.

Astragalus Extract is widely used in dietary supplements, functional foods, and research applications targeting immune health, cardiovascular function, anti‑aging, and overall vitality.

Astragalus P.E –Latin Name: Astragalus membranaceus (Fisch.) Bunge

Function

• Immunomodulation: Activates macrophages, NK cells, and T‑lymphocytes via polysaccharide components.

• Telomerase activation: Astragaloside IV (and its aglycone cycloastragenol) upregulates telomerase activity, supporting cellular longevity.

• Antioxidant activity: Flavonoids and polysaccharides scavenge free radicals, reducing oxidative stress.

• Adaptogenic support: Enhances resistance to physical and mental stress.

• Cardiovascular support: Supports healthy blood pressure and lipid profiles.

Source & Standardization Grades

• Source: Dried root of Astragalus membranaceus (Fisch.) Bge. or Astragalus mongholicus Bge.
