Natural Astragalus extract Astragaloside IV powder

Astragaloside IV is an organic compound with significant medicinal value, with the chemical formula C₄₁H₆₈O₁₄, appearing as a white crystalline powder. As one of the main active components of the traditional Chinese medicinal herb Astragalus, it, along with Astragalus polysaccharides and isoflavones, constitutes the pharmacological foundation of Astragalus. Astragaloside IV is particularly regarded as a key indicator for evaluating the quality of Astragalus medicinal materials.

In terms of physicochemical properties, Astragaloside IV has a relatively large molecular weight and is slightly soluble in water but dissolves well in organic solvents such as methanol and ethanol. This compound exhibits good stability, and its derivatives are rarely found in nature. However, exposure to temperatures above 300°C may compromise its structural stability.

Modern pharmacological research has revealed the extensive biological activities of Astragaloside IV. Not only is it the core substance responsible for the medicinal effects of Astragalus, but it also demonstrates broad therapeutic potential.

● Boosts both specific and nonspecific immune responses, helping the body eliminate foreign invaders.

● Enhances oxidative processes and increases the activity of immune-related enzymes such as GSH-PX and SOD, strengthening immune defense and surveillance.

● Stimulates macrophage and T-cell functions, increases E-rosette-forming cells, and induces cytokine production, leading to endogenous interferon synthesis.

● Inhibits influenza virus growth, suppresses neuraminidase activity, and disrupts viral membrane function, affecting viral adsorption and penetration into host cells.

● Demonstrates preventive and therapeutic effects on respiratory diseases such as infectious laryngotracheitis in poultry.

● Prevents adrenal hyperplasia and thymic atrophy during the early stages of stress response.

● Regulates metabolic enzymes, alleviating physiological disturbances caused by heat stress.

● Enhances cellular metabolism, improves blood circulation, and supports overall physiological function.

● Acts as a prebiotic by promoting the growth of beneficial gut bacteria such as Bifidobacteria and Lactobacilli.

● Strengthens myocardial contraction, protects the heart, and combats heart failure.

● Exhibits hepatoprotective, anti-inflammatory, and analgesic properties, making it a potential adjunct therapy for various viral and bacterial infections.
