Panasenoside as a marker for the discrimination of Ginseng root and leaf extracts

Both, Ginseng roots and leaves contain ginsenosides. Therefore, there is a chance that these extracts are mixed up. We have investigated roots and leaves of Panax ginseng C.A. Meyer and P. quinquefolius L. and found mainly quantitative differences in the content of ginsenosides. However, there was one characteristic blue fluorescent compound detected in Ginseng leaves, which could not be found in the roots. The compound has been isolated by preparative TLC and was finally identified by ms and nmr as kaempferol-3-O-glucosyl(1-2)galactoside, called panasenoside. Panasenoside was known as a constituent of leaves of P. ginseng [1]. However, this is the first report P. quinquefolius.

Panasenoside can be used as a marker for Ginseng leaf extracts and can be easily identified by HPTLC or HPLC.
