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 (see "Customer Notice").
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.
5:KING-TIGER® Astragalus Extract Products Can Fully Meet the Requirements of EU Regulations on PAHs.
Customer Notice:
Different species of the plant Astragalus have been traditionally used in a wild variety of herbal blends and “natural” remedies in China and other regions in Asia for thousands of years. They contain Astragalosides (Including Astragaloside IV), which are the ultimate source of the purified Cycloastragenol.
Cycloastragenol production process involves different steps, which are not novel, e.g., not involving new types of heat processing or non-thermal preservation methods, new processes to chill or freeze products or to dehydrate products, the application of new processes catalyzed by enzymes, etc. All steps are well experienced in the food supplement industry.
We found that not thoroughly studied production process 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 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%.
