Cycloastragenol

Details:

Plant source: The dry root of Astragalus membranaceus (Fisch. )Bge.(Main origin of Gansu) or Astragalus membranaceus (Fisch. ) Bge. var. mongholicus ( Bge. ) Hsiao(Main origin of Inner Mongolia)

Appearance: Brown yellow powder (1%, 5%, 10%), Light yellow powder (50%, 90%), White powder (98%, 99%)

Molecular Formula: C30H50O5

Molecular Weight: 490.72
CAS No: 78574-94-4, 84605-18-5                                               

Assay Test method: HPLC-RID or HPLC-ELSD

 Function:

1: Cycloastragenol has the function of enhancing immunity, protecting the body from diseases;

2: Cycloastragenol contains antioxidants, which protect cells against damage caused by free radicals;

3: Cycloastragenol has the effect on lowering blood pressure, treating diabetes and protecting the liver;

4: Astragalus membranaceus is the only telomerase activator found recently. By increasing telomerase and delaying telomere shortening, Astragalus membranaceus is considered to be an anti-aging agent.

The Characteristic of Chengdu King-tiger Cycloastragenol:

1: Chengdu King-tiger cycloastragenol product does not contain open-ring by-products astragenol, to ensure product safety and effectiveness.

2: Cycloastrageon 98% is pure white powder, HPLC purity is 99.00% above, can be directly used as a reference substance.

3: 100% natural extract of astragalus: low purity of cycloastragenol, in addition to contain cycloastragenol, the other ingredients are all natural ingredients of astragalus, such as astragalus polysaccharides, astragalus saponins, astragalus flavone etc.

4: All specifications can be provided from stock in large quantity at any time. Third-party test report will be provided with cycloastragenol.

Customer Notice:

Cycloastragenol was hydrolyzed from Astragaloside IV.

Chengdu King-tiger 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 Chengdu King-tiger developed can avoid producing astragenol, ensure the safety and effectiveness of the product. The detection method Chengdu King-tiger used can completely separate astragenol and cycloastragenol to ensure reliability of quality testing.

Let us take the cycloastragenol 98% on the market and the cycloastragenol 98% produced by Chengdu King-tiger for example:

For the cycloastragenol 98% on the market, according to the detection methods provided by suppliers, COA reported value is 98.74%.  

But according to Chengdu King-tiger detection methods, the testing result is only 60.45% in fact. There exists a large amount of astragenol.

For the cycloastragenol 98% produced by Chengdu King-tiger, there is completely no existence of astragenol and the purity reaches 99.33% for real.

NMR spectra also confirmed the purity of cycloastragenol 98% produced by Chengdu King-tiger.
