Ginsenosides, active compounds found in ginseng, are widely utilized in dietary supplements due to their numerous health benefits. They are known for their adaptogenic properties and their ability to support overall well-being.

Paying attention to the species of ginseng, the age of the plant, the part used for extraction, the processing method, the testing method, the solvents used, and the control measures for impurities will ensure that you acquire a superior ginseng extract for your valued natural products.

The active ingredients in Ginkgo biloba extracts are flavonoid glycosides and terpene lactone, which are present in concentrations of ≥24% and ≥6%, respectively. Current common analytical methods involve a hydrolysis step that converts flavonoid glycosides into aglycones. However, many aglycones are absent in the original ginkgo plant, yet they are used as quality control indicators for Ginkgo biloba products.
Now let’s see how they present in the HPLC figure.

Current common analytical methods involve a hydrolysis step that converts flavonoid glycosides into aglycones. However, many aglycones are absent in the original ginkgo plant, yet they are used as quality control indicators for Ginkgo biloba products. These inappropriate quality control indicators provide opportunities for adulterating Ginkgo biloba extracts.
