Abstract
This study investigated the extraction of essential oils from Indonesia basil (kemangi) leaf which have a
potential antibacterial agent using subcritical water. Effects of temperature and extraction time on yield and
product composition of basil oil obtained were study systematically. In this work, experiments were performed
in a tubular stainless steel reactor at temperature from 150oC to 215oC for 1 to 9 h of extraction at a certain
pressure (P= 40 bar)used fresh basil leaf. The yield and product composition of basil oils obtained were
affected by temperature and extraction time. The yield of basil oil increased with increasing extraction time.
However, yield of basil oil decreased from 1.41% to 1.2% with increasing temperature from 200oC to 215oC
for 9 h of extraction time. The composition of essential oils obtained were varied depending on the temperature
of extraction. Components in the basil oil which have an antibactial agent such as 1,8 Cineole, Tricosane and
Eugenol were identified using subcritical water at temperature 200oC.
