High Resolution GC-MS Analysis of Ginkgolic Acids in Ginkgo biloba Plants, Extracts, and Dietary Supplements Using the Agilent 5975C Series GC-MSD
4 May 2015

This application note describes a GC-MS method that produces high-resolution separation of the individual isomers of C13, C15, and C17 GAs in ginkgo leaves, extracts, and commercial products. It was also used to determine the double bond position and concentration of each isomer. This method was developed using the Agilent 7890 GC and the Agilent 5975C Series GC-MSD, and it provided resolution that could not be attained with the usual HPLC techniques.
