Enhancement of Minor Ginsenosides Contents and Antioxidant Capacity of American and Canadian Ginsengs () by Puffing.

The effects of puffing on ginsenosides content and antioxidant activities of American and Canadian ginsengs, , were investigated. American and Canadian ginsengs puffed at different pressures were extracted using 70% ethanol. Puffing formed a porous structure, inducing the efficient elution of internal compounds that resulted in significant increases in extraction yields and crude saponin content.
