Basil plants has potential as one source of essential oil applied in the flavor and fragrance industries. The isolation can be carried out by two methods, steam distillation and solvent extraction. This study analyzes the comparison of steam distillation and solvent extraction methods on the result of compound composition. The steam distillation process was performed for 4 hours, 6 hours, and 8 hours. Distillate was separated between the crude essential oil and water layer. The extraction process was performed for 6 cycles using n-hexane and ethanol as the solvent. The extract was separated between the basil essential oil and the solvent by rotary evaporator. Basil essential oil composition was analyzed using GC-MS. The result of the study shows that the basil essential oil composition obtained from solvent extraction is different with the results obtained from the steam distillation process. Isolation of carvacrol, hexadecanol, hydroxydihydromaltol, glycidyl methacrylate, 3-pyrroline, beta bisabolene, isopropyl butyrate, safrole, geraniol, carbamic acid, butyl alcohol 2-D1 (top note) are more effective by solvent extraction process with ethanol as the solvent. Isolation of geranial, neral, fanesol, alpha bergamotene, alpha bisabolene, and linalool is more effective by steam distillation process in 4 hours.

This study aims to extract vetiver oil by alternative extraction methods, namely ultrasonic extraction and soxhlet extraction. The performance of both extraction methods is compared based on the effect of extraction operation conditions with yield and quality parameters of vetiver oil produced. The quality of vetiver oil was determined and compared with SNI 06- 2386-2006. The specified quality parameters are color, odor, density, refractive index, and solubility in 95% ethanol. The composition of compounds in vetiver oil was identified by GC-MS method (Gas Chromatography-Mass Spectrometry). The results showed that ultrasonic extraction performed more effectively than soxhlet extraction. The ultrasonic extraction and soxhlet extraction gave an oil yield of 3.98±0.58% and 3.95±0.81%. In the extraction with ultrasonic aid performed in extraction time about 3/10 times shorter and solvent consumption about 2/3 times less compared with soxhlet extraction. In terms of quality, vetiver oil from ultrasonic extraction has eligible with the quality standard according to SNI 06-2386-2006 based on the test parameter. The GC-MS showed that vetiver oil from ultrasonic extraction composed of the mayor compounds of khusenic acid (36.40%), zierone (13.89%), nootkatone (1.92%), γ-selinene (1.57%), α-vetivone (1.43%), isolongifolene (1.32%), δ-cadinene (0.86%), and khusimene (0.64%).
