Abstract

Eugenol has been isolated and identified from oil of lawang (Cinnamomum cullilawan, BL). Before conducting isolation lawang oil was characterized. The eugenol was separated from the oil by fractional distillation under reduced pressure. The purities of all products were tested with gas liquid chromatography and determination of physical constants, such as refractive index and density. The structures were identified with infrared spectrophotometry, 1H nuclear magnetic resonance spectrometry, and mass spectrometry. The experimental result showed that the percentage yield of eugenol obtained from oil of lawang was 25,51 %.

Abstract

Has been conducted isolation of essential oil from Curcuma domestica. The separation of essential oil was conducted with steam distillation. The characteristic of essential oil were tested with gas chromatography, and determination of the specific gravity and refractive index. Thereafter the structures were identified with mass spectrometry. The experimental result showed that the components of essential oil of Curcuma domestica was: alfa-felandrene, cineol, zingiberene, beta-sesquifelandren, tumeron, spiro-4,4-nona-1,6-diene.

Abstract

Glycerol has been isolated from result of transterfication of castor oil by catalysis of potassium hydroxide in methanol. The purification were conducted by deguming, neutralizes, and bleaching. Thereafter, the structures were identified with gas chromatography-mass spectrometer and infrared spectrometer. The experimental result show that the percentages yield of glycerol was 28.1%.
