Cycloastragenol Ultimate Guide (2026) Everything You Need to Know About Cycloastragenol (CAG): Benefits, Manufacturing, Specifications, Applications & Buying Guide Author: CQHERB Technical Team Last Updated: July 2026 Estimated Reading Time: 18 Minutes What Is Cycloastragenol? Cycloastragenol (CAG) is a naturally occurring cycloartane-type triterpenoid aglycone derived from Astragalus membranaceus. It is most commonly obtained through the controlled hydrolysis or biotransformation of Astragaloside IV, one of the major bioactive saponins found in Astragalus root. Due to its extremely low natural abundance, commercial-scale Cycloastragenol is rarely produced through direct extraction. Instead, modern manufacturing relies on carefully controlled conversion technologies to achieve high purity and batch consistency. Today, Cycloastragenol has become one of the most extensively researched compounds from Astragalus species, attracting attention in healthy aging research, nutraceutical development, cosmetic ingredient innovation, and natural product science. Quick Answer Cycloastragenol is a high-value triterpenoid compound derived from Astragalus species. Commercial products are typically manufactured by converting Astragaloside IV into Cycloastragenol through hydrolysis or biotransformation processes. High-purity Cycloastragenol (≥98% HPLC) is widely used for dietary supplement formulation, cosmetic ingredient development, and scientific research. Key Takeaways Cycloastragenol is a rare aglycone naturally derived from Astragalus species. Commercial production primarily relies on Astragaloside IV conversion rather than direct extraction. High-purity material (≥98% HPLC) is preferred for research and premium formulations. Manufacturing technology plays a critical role in purity, impurity profile, and production cost. Professional suppliers should provide comprehensive quality documentation, including COA, SDS, TDS, and HPLC chromatograms. Table of Contents What Is Cycloastragenol?

Unlike Astragaloside IV, it does not contain sugar moieties, resulting in different physicochemical characteristics and formulation properties. Natural Sources of Cycloastragenol Cycloastragenol naturally occurs in several Astragalus species, including: Astragalus membranaceus Astragalus mongholicus Although naturally present, its concentration in the plant is extremely low. Direct extraction is therefore not considered commercially practical for large-scale production. Most high-purity Cycloastragenol available on the global market is produced through controlled conversion from Astragaloside IV. How Is Cycloastragenol Manufactured? Commercial Cycloastragenol production generally involves multiple controlled manufacturing steps to ensure purity and consistency. Step 1. Extraction of Astragalus Root Selected Astragalus roots are extracted to obtain crude saponins containing Astragaloside IV. Step 2. Purification of Astragaloside IV The extract undergoes multiple purification procedures to isolate high-purity Astragaloside IV. Step 3. Hydrolysis or Biotransformation Astragaloside IV is converted into Cycloastragenol using optimized hydrolysis or biotransformation technologies. Step 4. Purification The reaction product is purified through chromatographic separation and crystallization to remove impurities. Step 5. Quality Testing Each production batch is analyzed using HPLC and additional quality control methods before packaging.
