What is the difference between Astragaloside IV and Cycloastragenol?
Astragaloside IV is a natural glycoside extracted directly from Astragalus root with sugar chains. Cycloastragenol is the aglycone converted from Astragaloside IV. Astragaloside IV features better water solubility,for invigorating qi and consolidation of superficies while Cycloastragenol has higher lipophilicity and bioavailability for anti-aging and telomere-related applications.
What is the solubility of Astragaloside IV?
Astragaloside IV is slightly soluble in water. It has good solubility in DMSO, Ethanol and methanol. Heating and ultrasonic vibration can effectively improve the dissolution rate in aqueous solutions.
What purity grades of Astragaloside IV can you supply?
We supply multiple specifications tested by HPLC. Main specifications: 0.3%，0.5%，1%，2%，5%，10%, 20%, 50%, 90%, 98%. Bulk stock is available for large-scale orders. Third-party independent testing is acceptable upon request.
Can I get Astragaloside IV sample for lab testing?
Yes, small lab samples are available for your internal evaluation. Please contact our sales team to apply for samples.
What are storage condition and shelf-life for Astragaloside IV powder?
Store at room temperature, keep dry and protected from direct light and high humidity. Under proper storage condition, the shelf-life of solid powder is 3 years from the manufacturing date.
Why we ask you which region your customers are in?
Because regulatory requirements for astragalus extracts, including Astragaloside IV, differ widely from market to market: a product that meets specific specification limits in one market may be subject to entirely different test items and limits in another. The EU, for example, sets explicit limits on PAHs, and we provide the corresponding test reports and regulatory documentation required by the target market.
