Abstract
Isolation of linalool from coriander seeds by sohxlet extraction method – steam distillation has been carried out. This study used solvent variables, namely ethanol, hexane, a mixture of ethanol-hexane ratio of 1:1, and the variable mass of coriander seeds was 30, 35, 40, and 45 grams. This study aims to determine the right solvent to isolate linalool and determine the best yield that can be produced. Coriander seed powder was put into the Sohxlet extractor by adding 400 ml of solvent to isolate the linalool, then the solvent was separated using steam distillation. The extracts obtained were analyzed for the amount of yield, density, linalool functional groups using FTIR. From the research, it was found that ethanol solvent could isolate the most linalool with a yield of 31.52% and a density of 0.8667 gr/ml. In the mass variable, the largest yield was found in the mass of 30 grams of coriander powder by 39.3% and the density of 0.8670 gr/ml. The FTIR analysis showed the average wave number of –OH at 3316 - 3328 cm-1 and group C=C at 1641 cm-1.
