A New Approach to Authentication and Routine Screening of Ginsenoside Isomers in Functional Food Products

Ginseng is a slow-growing perennial plant believe to offer different therapeutic benefits such as CNS stimulant activity, hypoglycemic properties and sedative effects. Ion mobility is a rapid orthogonal gas separation phase technique that allows another dimension of separation to be obtained within an LC timeframe. This application note investigates the use of IM separation in combination with microflow chromatography to provide a route to specific and unambiguous identification of ginsenosides.
