The chemical composition of clove leaf essential oil obtained from steam distillation process Essential oils are needed in various industries such as industrial perfumes, cosmetics, pharmaceuticals, food industry, and beverages. This study aims to determine the chemical composition of clove leaf essential oil from steam distillation process using GCMS. Dry clove leaves weighing 1.5 kg are included in the kettle flute and sealed properly. Steam from the boiler flows into the kettle with the pressure of 0.5 barG, 1 barG and 1.5 barG for 5, 6 and 7 hours. Mixture oil and water out of the condenser are accommodated and let stand for 24 hours to separate water and oil. Clove leaf oil was purified with 10% bentonite by weight of oil at a temperature of 50oC with stirring for 1 hour. Clove leaf oil that has separated from bentonite added anhydrous Na2SO4 and let stand for 15 minutes and then separate the water and Na2SO4 in oil. Samples with % yield of the largest in its chemical composition analysis using GCMS. Based on the results obtained the largest yield is 1.84% with content of eugenol is 65.03% and 20.94% trans-caryophyllene.

Penelitian ini bertujuan untuk mengetahui komposisi kimia minyak atsiri daun cengkeh dari proses penyulingan uap menggunakan analisa GCMS. Daun cengkeh kering seberat 1,5 kg yang sudah bersih dari kotoran dimasukkan dalam ketel suling dan ditutup dengan rapat. Steam dari boiler dialirkan ke ketel suling dengan tekanan 0,5 barG, 1 barG dan 1,5 barG selama 5, 6 dan 7 jam. Campuran minyak dan air yang keluar dari kondenser ditampung dan diamkan selama 24 jam untuk memisahkan air dan minyak. Minyak daun cengkeh dimurnikan dengan bentonit 10% dari berat minyak pada suhu 50oC sambil diaduk selama 1 jam. Minyak daun cengkeh yang telah terpisah dari bentonit ditambahkan Na2SO4 anhidrat dan diamkan selama 15 menit kemudian pisahkan air dan Na2SO4 dalam minyak. Sampel dengan % rendemen terbesar di analisa komposisi kimianya menggunakan GCMS. Berdasarkan hasil penelitian didapat rendemen terbesar adalah 1,84% dengan kadar yaitu eugenol 65,03% dan trans-caryophyllene 20.94%.Kata kunci : Daun cengkeh, Eugenol, Minyak atsiri, Penyulingan uap

Lombok Island

Tea tree is an essential oil-producing plant from Australia which is also found growing in several parts of Indonesia, including the island of Lombok. So far, tea tree essential oil producers on the island of Lombok do not utilize by-products in the form of hydrosol (distilled water) produced in the process of making essential oils. In this study, the characterization and analysis of the chemical composition of the hydrosol of tea tree leaves growing on the island of Lombok was carried out. The characteristic aroma of hydrosol is similar to that of tea tree essential oil. The results of the GC-MS analysis also showed that the hydrosol of tea tree leaves also had similarities with the essential oil, composed of major compounds in the form of trans-caryophyllene (28.58%), limonene (13.98%) and terpinen-4-ol (16.27%). Other compounds detected were -pinene (4.14%), -pinene (6.50%), -myrcene (8.09%), -terpineol (10.10%) and -terpinene (5.77%).
