Abstract

Kaemferia galanga L. or kencur is a traditional plant that known has
potential antioxidant and anti-inflammatory activities because of its chemical
compound such as ethyl p-methoxycinnamate. This study aimed to analyze the
chemical compound of ethanolic extract of kencur using gas chromatography-mass
spectrometry. Kencur was extracted by cold maceration using ethanol-water
(70:30) at room temperature. From this procedure, the filtrate (extract of kencur)
and crystal are produced. The crystal then was crystallization using ethanol. The
ethanolic extract and crystal were analyzed qualitatively using gas
chromatography-mass spectrometry. The results show that in the ethanol extract
identified there were 5 compounds, namely ethyl-trans-p-methoxycinnamate
(84.55%); ethyl cinnamate trans (5.05%), methyl 4-methoxycinnamate (4.02%),
ethyl-cis-p-methoxycinnamate (2.85%) and benz[A]azulene-1,4-dione, 2,3-
dimethyl- (1.49%). Whereas the crystals are ethyl-trans-p-methoxycinnamate
(96.20%) and methyl 4-methoxycinnamate (1.62%). It was concluded that ethyl�trans-p-methoxycinnamate was the main compound of kencur which was easily
obtained by cold extraction.
