Customer Notice:

Cycloastragenol was hydrolyzed from Astragaloside IV.
We found that common hydrolysis method will generate a large amount of by-products named astragenol. Due to the similar structure with cycloastragenol, it is hard to separate the two when using HPLC to determine the assay, resulting in higher measured value than the actual value.
After seven years of research, the production technology we have developed can avoid producing astragenol, ensure the safety and effectiveness of the product. The detection method we used can completely separate astragenol and cycloastragenol to ensure reliability of quality testing.
We take the cycloastragenol 98% on the market and the cycloastragenol 98% produced by us for example:
For the cycloastragenol 98% on the market, according to the detection methods provided by suppliers, the chromatogram is as follows, COA reported value is 98.74%.  

Chromatogram 1: Cycloastragenol 98% on the market, tested by the methods provided by suppliers

It looks like pretty good! But according to our detection methods, the testing result is only 60.45% in fact, HPLC chromatogram as follows. We can clearly see that there exists a large amount of astragenol.

Chromatogram 2: Cycloastragenol 98% on the market, tested by our methods

For the cycloastragenol 98% produced by us, HPLC chromatogram as follows. There is completely no existence of astragenol and the content reaches 99.33% for real.

Chromatogram 3: Cycloastragenol 98% produced by us

NMR spectra also confirmed the purity of cycloastragenol 98% produced by us.

Chromatogram 4: 1H-NMR of cycloastragenol 98% produced by us

Report 5: Cycloastragenol 98% test report from USA third authorized independent lab
