Product Description
Astragaloside IV (AS-IV, CAS 84687-43-4) is the primary bioactive triterpene saponin purified from the dried roots of Astragalus membranaceus, a renowned traditional medicinal plant. As the definitive quality marker and most pharmacologically potent monomer in astragalus root extracts, Astragaloside IV features a unique cycloastragenol glycoside structure that delivers stable chemical properties and comprehensive multi-target biological activities. We supply premium research-grade and high-purity functional-grade Astragaloside IV powder with strictly controlled impurities, consistent batch activity and ultra-high single-component purity, fully compliant with global laboratory and functional ingredient production standards. Widely recognized for immunomodulation, multi-organ protection, anti-inflammation, antioxidation and anti-senescence capabilities, this natural saponin has become a core tool compound for modern pharmacological research and high-end anti-aging, immune-boosting raw material development.
Distinguished from mixed astragalus extracts and astragalus polysaccharides, pure Astragaloside IV possesses clear molecular structure, definite pharmacological targets and stable bioavailability, making it the gold-standard monomer for astragalus-related mechanism research. It exerts versatile regulatory effects on multiple human physiological systems, including immune, cardiovascular, nervous and renal systems. In immunological regulation, Astragaloside IV promotes immune cell proliferation, accelerates cytokine secretion and balances immune responses, effectively enhancing systemic immune defense and alleviating immune dysfunction. For organ protection, it improves myocardial microcirculation, inhibits cardiomyocyte apoptosis and reduces oxidative myocardial damage, providing reliable cardioprotective effects. Meanwhile, it repairs neuronal and renal tissue damage induced by oxidative stress and neuroinflammation, realizing dual neuroprotective and renoprotective functions.
In molecular pathway regulation, Astragaloside IV efficiently inhibits the overactivation of NF-κB, MAPK, p-Akt and p-mTOR signaling cascades, significantly reducing the release of pro-inflammatory cytokines and relieving chronic low-grade inflammation, a key driver of aging and chronic metabolic disorders. It also scavenges intracellular reactive oxygen species, mitigates lipid peroxidation damage and regulates cellular senescence progression, delivering dual anti-oxidative and anti-aging efficacy. Our high-precision purification process completely removes miscellaneous astragalus saponins, plant polysaccharides, fiber residues, heavy metals and organic solvent traces, eliminating experimental interference and ensuring pure monomer activity for high-precision scientific research and product formulation.
Manufactured by Shaanxi BAISFU Bio-Engineering Co., Ltd., our Astragaloside IV adopts standardized industrial production workflows including selective plant extraction, macroporous resin gradient separation, preparative HPLC fine purification and multi-stage low-temperature recrystallization. The whole production process is conducted in a dust-free, light-shielded and temperature-controlled closed system to prevent structural degradation of the triterpene saponin active skeleton and retain complete biological activity. The finished product presents uniform white crystalline powder with stable texture, no agglomeration and no discoloration, meeting international research-grade and functional ingredient quality requirements.
Every batch of Astragaloside IV undergoes strict multi-dimensional quality verification via HPLC purity testing, NMR structural identification, mass spectrometry molecular confirmation and cell-level activity evaluation. Ultra-low residual impurities and excellent batch-to-batch consistency guarantee reliable experimental repeatability and stable product efficacy. With favorable solubility in common organic solvents and superior biocompatibility in cell culture and in vivo animal models, our Astragaloside IV fully adapts to diverse scientific research scenarios and high-end functional product development. We support bulk stable supply, customized purity grades and professional low-temperature light-proof packaging, providing cost-effective high-purity raw materials for global research institutions, pharmaceutical laboratories and health product manufacturers.
