From: Fatty acid variability in three medicinal herbs of Panaxspecies
Typical GC chromatograms of P. ginseng (G), P. notoginseng (NG), P. quinquefolius (AG) and mixed standards determined by GC-MS. Fatty acid represents as the corresponding methyl ester. 1, myristic acid; 2, pentadecanoic acid; 3, palmitic acid; 4, palmitoleic acid; 5, heptadecanoic acid; 6, stearic acid; 7, oleic acid; 8, linoleic acid; 9, α-linolenic acid; 10, arachidic acid; 11, eicosadienoic acid; 12, lignoceric acid (Internal standard). The mixed standards contain 32 fatty acid methyl esters as described in section of Chemicals.
