| Abstract: | Epimedium L. (one of the Chinese herbal medicine) was stndied by GC/with FID. Fatty Acids were transferred to its methyl ester by means of rapid saponification and esterification with BF_3-MeOH.
Under the conditions of GC, the palmitic acid, octadecylic acid, oleic acid and linolic acid were separated well, and the concentrations were respectively 16.90, 19.85, 20.95, 22.10mg per gram dry leaves of Epimedium L. The recovery of palmitic acid and octadecylic acid were 100.3% and 100.4%. The average coefficient of variation was 2.88%. |
