BUYER DECISION GUIDE
When to Select the 30% Ginsenosides Grade
Select this grade when the purchasing specification requires Panax ginseng stem-and-leaf extract quantified to at least 30% ginsenosides by UV. Do not treat root extracts, raw ginseng powder, ratio extracts and standardised UV grades as interchangeable. Confirm botanical identity, plant part, analytical method and the offered-batch result before approval.
