Main Article Content


In this study, ethyl-p-methoxycinnamate (EPMC) was extracted from Kaempferia galanga L. by different methods. The study results show that vacuum drying process led to a significant decrease in EPMC content in the herb (about 7%); EPMC obtained by water distillation not only had a high purity and yield but could also be applied for both fresh and dried herb; whereas, Soxhlet extraction with n-hexane solvent brought the highest extraction yield (1.99% on dried herb weight) despite lower purity when compared to that by water distillation method.
