摘要：Steam distillation practices in cajuput oil industry usually use constant pressure.This study compared the yield and quality of cajuput oil from distillation with constant pressure and a stepwise increase of vapour pressure.The material density in distillation also should be considered because it can affect the yield of oil.The objectiveof this research was to understand the influence of material density on steam distillation with gradual increase of pressure on the yield and quality of cajuput oil produced.It was expected to obtain the highest yield that met specification of Standar Nasional Indonesia (SNI).Distillation carried out with 3 levels of material loading density,i.e.0.20,0.25,and 0.30 kg/l for 3.5 hours with the initial pressure gauge of 0 bar for 1.5 hours,then 0.5 bar at 1 hour later,and 1.0 bar at the last hour.The yield produced at distillation was 0.8% for constant pressure and ranged from 0.79% to 0.98% for stepwisely increase pressure.Material density did not have significant effects on yield,refractive index,and specific gravity,but only affected the optical rotation of cajuput oil.Increase in vapour pressure affected the characteristic of cajuput oil.Cineol content was 60.48% on the fraction of 0 bar pressure gauge,10.08% on the fraction of 0.5 bar pressure gauge,and 1.47% in fraction 1 bar pressure gauge.While cajuput oil from constant pressure contained cineol of only 35.70%.The main components of cajuput oil were cineol,α-terpineol,trans-carryophylene,viridiflorol,limonene,α-humulene,α-selinene,and β-selinene.
