Abstract

Kaempferia galanga L is a tropical plant that grows in many areas in Indonesia known as medicinal plants and herbal ingredients by the community. There are many secondary metabolite compounds in K. galanga such as ethyl cinnamic, paraffin, borneol, p-methoxystyrene and ethyl p-methoxycinnamate. The ethyl p-methoxycinnamate compound is known to be the major compound in K. galanga and is widely used in the cosmetic and anti-fungal. Many benefits of the ethyl p-methoxycinnamate compound make the need for this compound constantly increasing and the need for an isolation method that can produce this compound in large quantities. The isolation method used in this research is the soxhletation method using ethanol solvent and recrystallization using n-hexane solvent. Samples of K. galanga were used as much as 50 gram and obtained crystalline ethyl p-methoxycinnamate as much as 0.49 gram with percentage of rendement as much 0.98%. The resulting crystalline ethyl p-methoxycinnamate has been identified using UV-vis spectroscopy, IR and H-NMR.
