Isolasi Etil P-metoksisinamat Dari Rimpang Kencur (Kaempferia Galangal L.) Dan Identifikasinya Dengan Kromatografi Gas Spektroskoi Massa

Abstract

EPMS – Ethyl p-methoxycinnamate was one of compound isolated from greater galingale rhizome (Kaempferia galanga L.) can be used as base substance of sun screen product. The method used in this research was percolation. The obtained percolate was dried until crystal was formed. The obtained crystal was later recrystallization. The result showed that greater galingale N-hexane extract possibly contained EPMS. The isolated substance had high solubility and purity (96,92%), it was seen from Gas Cromatograph Mass Spectrometer spectra that show one dominant peak. Keywords: EPMS, greater galingale (Kaempferia galanga L.), isolation, GCMS
