Cycloastragenol (CAS 78574-94-4) is a high-purity, plant-derived single compound extracted from Astragalus membranaceus using a water-and-alcohol solvent process. Standardized to ≥98% purity by HPLC at 210 nm, it is one of the most sought-after actives in premium anti-aging, longevity and cellular-health supplement formulations.
KEEP INGREDIENTS supplies cycloastragenol bulk powder as a white to off-white fine powder, 100% through 80 mesh, with heavy metals and micro limits far below generic botanical extract specifications.
Every order ships with a lot-specific cycloastragenol COA detailing the exact HPLC method (Agilent 1100, C18 column, UV-VIS detection), loss on drying, ash, and ICP-MS heavy-metal results — so R&D and QA teams can drop our material directly into their validation batches.
