BUYER DECISION GUIDE
When to Select the 7% Withanolides Grade
Select this grade when the purchasing specification requires a root extract quantified to 7% withanolides by HPLC. Do not treat raw ashwagandha powder, ratio extracts and standardised HPLC grades as interchangeable. Confirm botanical identity, plant part, analytical method and the offered-batch result before approval.
