Introduction

Astragalus membranaceus (Fisch.) Bunge, a perennial plant belonging to the Fabaceae family, has been used in traditional wellness practices for centuries. Astragaloside IV (CAS 84687-43-4) stands out as the most extensively studied tetracyclic triterpenoid saponin, recognized as a key quality indicator for Astragalus root extracts in pharmacopoeial standards. At Dielegance Biotech, we offer two complementary grades to meet diverse formulation needs: Astragalus Root Extract standardized to 5% Astragaloside IV and High-Purity Astragaloside IV 98%.

  • Firming lotions and treatments

  • Barrier-repair formulations

  • Advanced delivery systems (ethosomes, liposomes)
     

Research and Reference Standards

The 98% purity grade also serves as a research-grade material for analytical reference and biological studies.

 

Critical Process Guidelines:
Temperature: Sensitive to heat; avoid processing above 60°C
Storage: Must be stored frozen (-10°C to -20°C) under inert gas 
Moisture: Hygroscopic; protect from moisture during handling
