Abstract

The fatty acids in Illicium verum Hook.f. grown in Zhumadian and Yulin were extracted by ultrasonic-assisted extraction or Soxhlet extraction, methyl esterificated and then analyzed by GC-MS. The extraction yields of fatty acids from Chinese star anise grown in Zhumadian and Yulin were 26.65% and 34.30% by ultrasonic-assisted extraction and 15.45% and 20.55% by Soxhlet extraction, respectively. The fatty acid composition of Chinese star anise varied little with geographic area and extraction method. The dominant fatty acids were hexadecanoic acid, heptadecanoic acid, octadecanoic acid, linoleic acid and oleic acid.
